    Distal ulna fractures in adults - subcapitular, transverse fractures did not benefit from surgical treatment2023Ingår i: Archives of Orthopaedic and Trauma Surgery, ISSN 0936-8051, E-ISSN 1434-3916, Vol. 143, nr 1, s. 381-387Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction Fractures of the distal ulna, excluding the styloid, are rare. The cause of injury is often a fall on an outstretched hand with an extended wrist, and in most cases there is a concomitant distal radius fracture. The aims of this retrospective study were to investigate the results of the current treatment of distal ulna fractures in adults, with or without a concomitant distal radius fracture, and if a recently presented fracture classification could predict outcome. Materials and methods Patients, 18 years or older, treated for a fracture of the distal third of ulna in our county, were included. Fractures of the styloid tip were excluded. The radiographs of the fractures were independently classified by two specialists in radiology according to the 2018 AO/OTA classification. Follow-up was performed 5-7 years after the injury, through the questionnaire Patient-Rated Wrist Evaluation (PRWE) and new radiographs of both wrists. Results Ninety-six patients with 97 fractures were included and filled out the PRWE. 65 patients also had new radiographs taken. 79 patients were women and the mean age at the time of injury was 63 years (SD 14.5). The most common fracture class was the extra-articular transverse fracture, 2U3A2.3 (42%). We found that 40% of the fractures had been treated by internal fixation and only 2 fractures had not healed, one conservatively treated and one operated. The median PRWE was 15 (IQR 33.5). The PRWE score was significantly worse in the operated ulna fractures (p = 0.01) and this was also true for extra-articular transverse fractures 2U3A2.3 (p = 0.001). Initial displacement was more common in operated transverse fractures, but it could not be proven that this was the reason for the inferior result. Conclusions Distal ulna fractures almost always unite and the result is comparable to that of isolated distal radius fractures when measured by PRWE. Based on the opinions of the radiologists and how often a consensus discussion was needed for classification, we found the updated AO classification system difficult to use, if dependent only on standard radiographic views. In the present study, transverse extra-articular ulna fractures did not benefit from internal fixation regardless if associated with a distal radius fracture or isolated.

    The Choice of Antibiotic Prophylaxis Influences the Infection Reoperation Rate in Primary Shoulder Arthroplasty: Analysis From the Swedish Shoulder Arthroplasty Register2023Ingår i: Clinical Orthopaedics and Related Research, ISSN 0009-921X, E-ISSN 1528-1132, Vol. 481, nr 4, s. 728-734Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Periprosthetic joint infection is a serious complication and a major reason for revision surgery after primary shoulder arthroplasty. The prophylactic antibiotics for primary shoulder arthroplasty that have predominantly been used in Sweden are cloxacillin and clindamycin. To address Cutibacterium acnes, benzylpenicillin has recently increasingly been added to cloxacillin, but it is unclear which antibiotic prophylaxis regimen is the most effective to prevent periprosthetic joint infection. Questions/purposes After controlling for baseline differences among patients such as age, gender, previous surgery, cement fixation, and arthroplasty type, was the risk of reoperation for infection higher in patients who received cloxacillin than in those who received clindamycin or the combination of benzylpenicillin and cloxacillin? Methods Data from the Swedish Shoulder Arthroplasty Register were used for this study. The inclusion criterion was registered antibiotic prophylaxis in primary arthroplasty. Between January 1, 1999, and December 31, 2019, 22,470 primary shoulder arthroplasties, including total shoulder, hemiarthroplasty, and reverse shoulder arthroplasties, were entered into the Swedish Shoulder Arthroplasty Register. Reporting of antibiotic prophylaxis to the register was introduced on January 1, 2013. Since then, the completeness of information on the type of antibiotic prophylaxis in the reports has been 85.3%. Consequently, 10,706 arthroplasties were eligible and fulfilled the inclusion criterion of reported antibiotic prophylaxis. A further 129 were excluded because of unusual prophylaxis regimens, leaving 10,577 shoulder arthroplasties for analysis. The Swedish Shoulder Arthroplasty Register gathers information from all 60 hospitals performing shoulder arthroplasty in Sweden, and through a comparison with the National Patient Register, it has been estimated that more than 90% of all primary shoulder arthroplasties and shoulder reoperations are reported to the register. The age of the study population ranged between 16 and 98 years; the mean age at the primary surgery was 70 +/- 10 years for the entire cohort, with a mean age of 67 +/- 10 years and 72 +/- 9 years for men and women, respectively. The mean observation period was 989 +/- 669 days. From 2013 to 2019, there was a clear change in prophylaxis; in particular, the use of the combination of benzylpenicillin and cloxacillin increased dramatically and the use of cloxacillin alone decreased. Clindamycin prophylaxis increased moderately. The primary study endpoint was reported reoperation for infection. In the register, this is defined as repeat procedures of any kind, including biopsy, lavage of the joint, or revision, defined as secondary surgery in which a component was exchanged, removed, or added. To compare the reoperation rate in relation to the different antibiotics used, which changed over time, we controlled for age, gender, previous surgery, cement fixation, and arthroplasty type using a Cox proportional hazards model. Results When adjusting for age, gender, previous surgery, cement fixation, and arthroplasty type, cloxacillin prophylaxis was associated with an increased relative risk of reoperation for infection compared with the combination of cloxacillin and benzylpenicillin (hazard ratio [HR] 2.40 [95% confidence interval (CI) 1.35 to 4.25]; p = 0.003) and compared with clindamycin alone (HR 1.78 [95% CI 1.11 to 2.85]; p = 0.02). No difference was found between the cloxacillin and benzylpenicillin combination and clindamycin (HR 0.74 [95% CI 0.42 to 1.32]; p = 0.31). Conclusion Our results indicate that prophylaxis against C. acnes may be warranted in shoulder arthroplasty. Because the absolute number of infections was low and infections could have been underreported to the register, our results should be interpreted with caution. There is no available information about the causative microorganisms. The study lays the groundwork for further investigations of antibiotic prophylaxis regimens in shoulder arthroplasty. Because large randomized controlled trials would be impractical to perform, prospective register-based randomized controlled studies might be a viable method.

    Poor reliability and reproducibility of 3 different radiographical classification systems for distal ulna fractures2022Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 93, s. 438-443Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose - Classification of fractures can be valuable for research purposes but also in clinical work. Especially with rare fractures, such as distal ulna fractures, a treatment algorithm based on a classification can be helpful. We compared 3 different classification systems of distal ulna fractures and investigated their reliability and reproducibility. Patients and methods - patients with 97 fractures of the distal ulna, excluding the ulnar styloid, were included. All fractures were independently classified by 3 observers according to the classification by Biyani, AO/OTA 2007, and AO/OTA 2018. The classification process was repeated after a minimum of 3 weeks. We used Kappa value analysis to determine inter- and intra-rater agreement.

    Results - The inter-rater agreement of the AO/OTA 2007 classification was judged as fair,. 0.40, whereas the agreement of AO/OTA 2018 and Biyani was moderate at. 0.42 and 0.43 respectively. The intra-rater agreement was judged as moderate for all classifications. Interpretation - The differences between the classifications were small and the overall impression was that neither of them was good enough to be of substantial clinical value. The Biyani classification, being developed specifically for distal ulna fractures, was the easiest and most fitting for the fracture patterns seen in our material, but lacking options for fractures of the distal diaphysis. Standard radiographs were considered insufficient for an accurate classification. A better radiographic method combined with a revised classification might improve accuracy, reliability, and reproducibility.

    Scandinavian Olecranon Research in the Elderly (SCORE): protocol for a non- inferiority, randomised, controlled, multicentre trial comparing operative and conservative treatment of olecranon fractures in the elderly2022Ingår i: BMJ Open, E-ISSN 2044-6055, Vol. 12, nr 1, artikel-id e055097Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction The incidence of olecranon fractures is growing in the elderly population. The traditional operative approach is giving way among the elderly to conservative treatment, which seems to provide a comparable functional outcome with a lower complication burden. However, there is still a lack of reliable evidence to support this shift. The objective of this trial is to investigate whether conservative treatment of displaced olecranon fractures in patients aged 75 or older yields comparable results to those of operative treatment in terms of pain and daily function. Methods and analysis Scandinavian Olecranon Research in the Elderly (SCORE) is a randomised, controlled, multicentre, non-inferiority trial. Eligible patients will be randomised to either conservative or operative treatment. The sample size will be 68 patients and allocation done at a 1:1 ratio (34 patients per group). The randomisation is stratified according to the participating hospital and patients sex. Both groups will receive the same postoperative physiotherapy and pain management. The primary outcome is Disabilities of the Arm, Shoulder and Hand at 1-year follow-up. Secondary outcomes are pain and satisfaction measured on visual analogue scales, Patient Reported Elbow Evaluation, range of motion of the elbow and extension strength of the elbow compared with the unaffected arm. Radiographs will be taken at each follow-up. Primary analysis of the results will be conducted on an intention-to-treat basis. Ethics and dissemination The study protocol for this clinical trial has been approved by the Ethics Committee of the Hospital District of Southwest Finland and will be submitted for approval to the Regional Ethics Committees in Linkoping, Sweden and Copenhagen, Denmark. Every recruiting centre will apply local research approvals. The results of this study will be submitted for publication in peer-reviewed journals.

    Biomechanical significance of the collateral ligaments in transolecranon fracture-dislocations2021Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 30, nr 6, s. 1245-1250Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: It is widely accepted that transolecranon fracture-dislocations are not associated with collateral ligament disruption. The aim of the present study was to investigate the significance of the collateral ligaments in transolecranon fractures. Methods: Twenty cadaveric elbows with a mean age of 46.3 years were used. All soft tissue was dissected to the level of the capsule, leaving the anterior band of the medial collateral ligament (MCL) and lateral collateral ligament (LCL) intact. A standardized, oblique osteotomy starting from the distal margin of the cartilage bare area of the ulna was made. The elbows were loaded with an inferiorly directed force of 5 and 10 N in the intact, MCL cut, LCL cut, and both ligaments cut states. All measurements were recorded on lateral calibrated radiographs. Results: The mean inferior translation with intact ligaments (n 20) when the humerus was loaded with 5 and 10 N was 1.52 mm (95% confidence interval [CI], 1.02-2.02) and 2.23 mm (95% CI, 1.61-2.85), respectively. When the LCL was cut first (n = 10), the inferior translation with 5 and 10 N load was 4.11 mm (95% CI, 0.95-7.26) and 4.82 mm (95% CI, 1.91-7.72), respectively. When the MCL was cut first (n - 10), the inferior translation when loaded with 5 and 10 N was 3.94 mm (95% CI, 0.796-7.08) and 5.68 mm (95% CI, 3.03-8.33), respectively. The inferior translation when loaded with 5 and 10 N and both ligaments cut was 15.65 mm (95% CI, 12.59-18.79) and 17.50 mm (95% CI, 14.86-20.13), respectively. There was a statistical difference between the intact and MCL cut first at 10 N and when both ligaments were cut at 5 and 10 N. Conclusions: The findings suggest that collateral ligament disruption is a prerequisite for a transolecranon fracture-dislocation. An inferior translation of more than 3 mm suggests that at least one of the collateral ligaments is disrupted, and more than 7.5 mm indicates that both collateral ligaments are disrupted.

    Fluoroscopy of the Elbow: A Cadaveric Study Defining New Standard Projections to Visualize Important Anatomical Landmarks2021Ingår i: JB & JS open access, ISSN 2472-7245, Vol. 6, nr 2, artikel-id e20.00160Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Despite new 3-dimensional imaging modalities, 2-dimensional fluoroscopy remains the standard intraoperative imaging modality. The elbow has complex anatomy, and defined standard fluoroscopic projections are lacking. Therefore, the aim of this study was to define standard projections of the elbow for intraoperative fluoroscopy. Methods: This study consisted of 2 parts. In part I, dissected cadaveric elbows were examined under fluoroscopy, and their radiographic anatomical features were assessed, with focus on projections showing defined anatomical landmarks. In part II, projections from part I were verified on entire cadavers to simulate intraoperative imaging. Standard projections for anteroposterior (AP) and lateral views as well as oblique and axial views were recorded. Results: Eight standardized projections could be defined and included 3 AP, 1 lateral, 2 oblique, and 2 axial views. By applying these specific projections, we could visualize the epicondyles, the trochlea with its medial and lateral borders, the capitellum, the olecranon, the greater sigmoid notch, the coronoid process including its anteromedial facet, the proximal radioulnar joint with the radial tuberosity, and the anterior and posterior joint lines of the distal part of the humerus. These standard projections were reliably obtained using a specific sequence. Conclusions: Knowledge about radiographic anatomy and standard projections is essential for visualizing important landmarks. With the presented standard projections of the elbow, important anatomical landmarks can be clearly examined. Thus, fluoroscopic visualization of anatomical fracture reduction and correct implant placement should be facilitated. Clinical Relevance: This basic science cadaveric study defines fluoroscopic standard projections of the elbow essential for visualization of anatomical landmarks during surgery.

    Heterogeneity among patients with subacromial pain – variabilities within clinical presentation and its impact on daily life2021Ingår i: Physiotherapy, ISSN 0031-9406, E-ISSN 1873-1465, Vol. 112, s. 113-120Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The primary aim was to describe the variability within clinical presentation of patients with subacromial pain in primary care, secondly to investigate associations between clinical presentation and self-reported pain intensity, shoulder function, level of anxiety and depression, and health-related quality of life. Design and setting A cross-sectional study based on data from two clinical studies in primary care, one randomized controlled trial and one implementation study. Three components: active range of motion (AROM), rotator cuff function and scapular kinematics were analyzed to describe variability within clinical presentation and patient-reported measurements were used to investigate the impact on daily life. Participants Patients aged 30-67 years, describing pain for more than two weeks, and positive signs for a minimum of three out of the following five clinical tests: impingement sign according to Neer, impingement test according to Hawkins-Kennedy, Pattes maneuver, Jobe’s test, and painful arc. Results Among the 164 patients included, 24% displayed dysfunction in one, 50% two and 24% in all three components. Limited AROM was seen in 46%, rotator cuff dysfunction in 91% and scapular dyskinesia in 57% of the patients. Conclusions These results reveal a heterogeneity among primary care patients with subacromial pain confirming a large variability regarding the components AROM, rotator cuff function and scapular kinematics. All three components appear unique (not significantly correlated) where a rotator cuff dysfunction is very frequent while limited AROM and scapular dyskinesia are more inconsistent. There are significant, but rather weak, associations between clinical presentation and impact on daily life.

    Neither critical shoulder angle nor acromion index were related with specific pathology 20 years later!2021Ingår i: Knee Surgery, Sports Traumatology, Arthroscopy, ISSN 0942-2056, E-ISSN 1433-7347, Vol. 29, nr 8, s. 2648-2655Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose The critical shoulder angle (CSA) and the acromion index (AI) are measurements of acromial shape reported as predictors of degenerative rotator cuff tears (RCT) and glenohumeral osteoarthritis (GH OA). Whether they are the cause or effect of shoulder pathologies is uncertain since pre-morbid radiographs most often are lacking. The main aim of this study was to investigate if CSA or AI were related to the development of RCT or GH OA after 20 years. A secondary aim was to investigate if the CSA and AI had changed over time. Methods In the hospital archive, 273 preoperative plain shoulder radiographs were found of patients scheduled for elective surgery other than cuff repair and arthroplasty. Forty-five images fulfilled the strict criteria published by Suter and Henninger (2015) and were used to measure CSA and AI with two independent assessors. No patient had any sign of OA in the index radiographs or any information in the medical records indicating RCT. After a median of 20 (16-22) years, 30 of these patients were radiologically re-examined with bilateral true frontal views and ultrasound of the rotator cuff. There were 19 men (20 study shoulders) and 11 females (12 study shoulders). Results Mean age at follow-up was 56 (32-78) years. There was no correlation between CSA (r = 0.02) (n.s) or AI (r = - 0.13) (n.s) in the primary radiographs and OA at follow-up. Nor was any correlation found between index CSA (r = 0.12) (n.s) or AI (r = - 0.13) (n.s) and RCT at follow-up. Mean difference in CSA was - 1.7 (- 10-3) degrees and mean AI difference was - 0.04 (- 0.13-0.09) between the first and the second radiographs, 20 years later. Bilaterally, mean CSA was 32 and AI 0.61 at follow-up. Conclusion In this study, no correlation between the CSA, AI and development of OA or RCT could be found. The mean CSA and AI decreased over a 20-year period but the difference was very small. No difference was found between the study shoulders and the contralaterals. These findings question previously reported etiological associations between scapular anatomy and the development of OA or RCT and thereby the use of these calculations as the basis of treatment.

    The minimal important change for the seven-item disability of the arm, shoulder, and hand (DASH 7) questionnaire - Assessing shoulder function in patients with subacromial pain.2021Ingår i: JSES international, ISSN 2666-6383, Vol. 5, nr 3, s. 474-479Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The DASH 7 is a recently published activity-related 7-item short form of the disability of the arm, shoulder, and hand (DASH) questionnaire developed to assess shoulder function in patients with subacromial pain. Before implementation in both intervention studies and in clinical practice, it is essential to evaluate its responsiveness. The objective of this study was to determine the minimal important change (MIC) in the DASH 7 questionnaire for patients with subacromial pain after a 3 months exercise intervention in a primary care context.

    Methods: In this psychometric study the anchor-based MIC-distribution method was used to establish the MIC. The Patient Global Impression of Change (PGIC) was used as external criterion. Data from a clinical implementation study, aimed to implement a specific exercise strategy for patients with subacromial pain among physiotherapists in primary care, were used. Data from 70 patients were included in the analyses.

    Results: The correlation coefficient between Patient Global Impression of Change and the DASH 7 score change was 0.67 and the area under the curve was 0.94 (95% confidence interval: 0.88-1.0). The MICROC for improvement was detected at a mean change in 6.5 points with the sensitivity at 0.98 (98%) and the specificity at 0.78 (78%), and the MIC95% limit for improvement was detected at a mean change of 25.7 points. There were 77% of the patients who reached at least this MICROC and 51% who reached at least the MIC95% limit after 3 months of exercise intervention.

    Conclusion: The DASH 7 is responsive to change over time and can discriminate between patients considered to be improved and patients considered not improved. These MIC values for patients with subacromial pain in the primary care setting can be used in clinical practice and in intervention studies as an indication on the patients clinically important level of score change for improvement.

    An intact lacertus fibrosus improves strength after reinsertion of the distal biceps tendon2020Ingår i: Knee Surgery, Sports Traumatology, Arthroscopy, ISSN 0942-2056, E-ISSN 1433-7347, Vol. 28, nr 7, s. 2279-2284Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose The importance of an intact lacertus fibrosus in distal biceps tendon injury is uncertain. This study aimed to assess long-term outcome following distal biceps tendon repair with focus on the significance of the lacertus fibrosus. Methods Thirty-six patients surgically treated for primary distal biceps tendon rupture were identified. Medical records were reviewed for patient demographics in addition to surgery-related data. All patients underwent a targeted clinical examination to assess elbow function and they completed a patient reported questionnaire. Radiographs were obtained at time of follow-up and evaluated for the presence of osteoarthritis (OA) and heterotopic ossification (HO). Results All patients were male. Median age at injury was 48 years (34-69) and median time of follow-up of was 71 months (23-165). All patients presented functional range of motion in the elbow. Median flexion strength was 76 Nm (45-135) (median 99% of uninjured side; range 66-128) with intact lacertus fibrosus and 70 Nm (43-124) (88%, 62-114) with torn lacertus fibrosus. Median supination strength was 6 Nm (3-11) (86%, range 36-144) with intact lacertus fibrosus and 8 Nm (3-17) (67%, 28-118) with torn lacertus fibrosus. No signs of OA were revealed, but three patients had major HO of which one patient had minor limitations in range of elbow motion. Conclusion An intact lacertus fibrosus contributes to elbow strength and should be preserved in distal biceps tendon repair.

    Incidence of distal ulna fractures in a Swedish county: 74/100,000 person-years, most of them treated non-operatively2020Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 91, nr 1, s. 104-108Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose - Fractures of the distal ulna can occur in isolation or in conjunction with a distal radius fracture. They may result in incongruence and instability of the distal radioulnar joint. We investigated the incidence of distal ulna fractures, whether any fracture types were more common, and the methods of treatment used. Patients and methods - Data were collected from patients 18 years or older, treated for a fracture of the distal ulna in ostergotland, Sweden, during 2010-2012. Patients were identified in the patient registry. The fractures were classified according to the AO comprehensive classification of fractures. Results - The incidence of distal ulna fractures was 74/100,000 person-years. The most common fracture type was that of the ulnar styloid Q1 (79%), followed by the ulnar neck Q2 (11%). Rarest was ulna head fracture, type Q4 (1%). Incidental findings were a mean age of 63 years (SD 18), a concomitant distal radius fracture in 92% of the patients and that 79% were caused by falling from standing height. Internal fixation was performed in 30% of the Q2-Q6 fractures. This indicates that most were considered stable without internal fixation or stable after fixation of a concomitant radius fracture. Interpretation - Our results show that fractures of the distal ulna are not very common, and some fracture types are even rare. There seem to be no consensus on treatment.

    Surgery and physiotherapy were both successful in the treatment of small, acute, traumatic rotator cuff tears: a prospective randomized trial2020Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 29, nr 3, s. 459-470Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Previous randomized trials on cuff repair have included mainly degenerative tears, but studies on acute traumatic tears are lacking. We aimed to compare early surgical repair with nonoperative treatment for traumatic supraspinatus tears. Methods: We did a 2-center randomized controlled trial of patients with small rotator cuff tears mainly involving supraspinatus, comparing surgical repair (n = 32) and physiotherapy (n = 26). The primary outcome was a group difference in the Constant-Murley score at 12-month follow-up. Secondary outcomes were differences in the Western Ontario Rotator Cuff index, pain (Numerical Rating Scale 0-10), and Euro quality-of-life-visual analog scale. We used magnetic resonance imaging to assess retear rate, tear progression, fatty infiltration, and atrophy. Results: The mean age was 59.7 years (range, 44-77 years), median sagittal tear size was 9.7 mm (range, 421 mm), and baseline characteristics were well balanced between the 2 groups. The repair group had a median Constant-Murley of 83 (25 quartile range [QR)) and the physiotherapy group 78 (QR, 22) at 12 months, with the between-group difference in medians of 4.5 (-5 to 9, 95% confidence interval; P = .68). The corresponding values for the Western Ontario Rotator Cuff index were 91% (QR, 24) vs. 86% (QR, 24), with the between-group difference of 5.0 (-4 to 9, 95% confidence interval; P- .62). There was no difference in Numerical Rating Scale or in Euro quality-of-life-visual analog scale. Retear was found in 63% of repaired patients and tear progression amp;gt;5 mm in 29.2% of unrepaired patients. Conclusions: We found no significant differences in clinical outcomes between cuff repair and nonoperative treatment at 12-month follow-up. Approximately one third of unrepaired patients had a tear enlargement of more than 5 mm. (C) 2019 Journal of Shoulder and Elbow Surgery Board of Trustees. All rights reserved.

    Arthroplasty as primary treatment for distal humeral fractures produces reliable results with regards to revisions and adverse events: a registry-based study2019Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 28, nr 4, s. E104-E110Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Primary prosthetic replacement has become an accepted method for the treatment of complex distal humeral fractures. The present study investigated implant survival and adverse events related to this procedure based on available Swedish registries and examined the completeness of the Swedish Elbow Arthroplasty register.

    Materials and methods

    Patients treated in Sweden with a primary elbow replacement due to a distal humeral fracture between 1999 and 2014 were identified through 3 different registries: The Swedish Elbow Arthroplasty Register, National Board of Health and Welfare inpatient register, and local registries of all orthopedic departments. Prosthetic survival was examined using Cox regression analysis with Kaplan-Meier plots. Adverse events, defined as medical treatment of the affected elbow besides revision, were analyzed separately. The study included 406 elbows in 405 patients, and no register was complete.

    Results

    Implant survival at 10 years was 90% (95% confidence interval, 85%-96%), but only 45 patients had an observation time of 10 years or more because 46% of the patients had died, resulting in a mean observation time of 67 (standard deviation, 47) months. An increase in the use of hemiarthroplasties and a proportional decrease of total elbow arthroplasties was detected. There were 18 revisions (4%), and 26 patients (6%) experienced an adverse event, of whom 16 (4%) required surgery. The completeness of the Swedish Elbow Arthroplasty Register regarding primary arthroplasty was 81%.

    Conclusion

    Primary arthroplasty as treatment of distal humeral fractures produces reliable results with regards to revisions and other adverse events.

    20-Year outcome of TFCC repairs2018Ingår i: Journal of Plastic Surgery and Hand Surgery, ISSN 2000-656X, E-ISSN 2000-6764, Vol. 52, nr 3, s. 193-197Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aims of this study were to investigate the functional result and rate of osteoarthritis 15-25 years after a TFCC-repair. Forty-seven patients completed the questionnaire Patient Rated Wrist Evaluation (PRWE), and 43 had new X-rays. Fifty-seven percent had a simultaneous arthroscopy. Sixteen patients had later additional surgery to the wrist, of these eight had a reoperation of the TFCC-injury due to recurrent instability. Radiographs showed that 17.5% had developed radiocarpal osteoarthritis and 34% osteoarthritis in the distal radioulnar joint. The median PRWE result was 22.5. Patients with radiocarpal osteoarthritis and patients who had additional surgery had significantly worse scores. Patients who had undergone arthroscopy significantly less often had developed radiocarpal osteoarthritis. The result is acceptable but not impressive and efforts should be made to diagnose these injuries early and also diagnose associated injuries, advisably by arthroscopy.

    Long-term clinical and radiographic outcome of rotator cuff repair with a synthetic interposition graft: a consecutive case series with 17 to 20 years of follow-up2018Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 27, nr 9, s. 1622-1628Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Treatment options for irreparable cuff tears include synthetic interposition grafts, but whether such grafts can maintain acceptable shoulder function and prevent cuff tear arthropathy in the long-term is unknown.

    Method

    This was a retrospective case series of 13 consecutive patients treated with a synthetic interposition graft made of Dacron (DuPont, Wilmington, DE, USA). Patients were examined with bilateral ultrasonography, bilateral x-ray imaging, Constant-Murley score, and Western Ontario Rotator Cuff score.

    Results

    After a mean of 18 years (range, 17-20 years), 1 patient had died, and 12 were available for x-ray imaging and 10 also for ultrasonography and clinical scores. Cuff tear arthropathy (Hamada grade ≥2) had developed in 9 of 12 (75%; 95% confidence interval, 43%-95%), including 3 patients operated on with arthroplastyin the follow-up period. The mean absolute Constant-Murley score was 46 (standard deviation, 26), and the mean Western Ontario Rotator Cuff score was 59 (standard deviation, 20). In 7 of 10 patients (70%) with available ultrasonography, the graft was interpreted as not intact. All patients had a contralateral full-thickness tear, and 7 of 12 patients (58 %; 95% confidence interval, 28%-85%) had contralateral cuff tear arthropathy. The number of patients with cuff tear arthropathy was not significantly different between the shoulder repaired with a Dacron graft and the contralateral shoulder (P = .667).

    Conclusion

    These results indicate that a synthetic interposition graft with screw fixation could not prevent cuff tear arthropathy and preserve cuff integrity in a long-term perspective.

    Patients with a long-standing cuff tear in one shoulder have high rates of contralateral cuff tears: a study of patients with arthroscopically verified cuff tears 22 years ago2018Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 27, nr 3, s. E68-E74Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The prevalence of contralateral full-thickness cuff tears (FTTs) and cuff tear arthropathy (CTA) is presumed to be higher in patients with long-standing cuff tears than in those with newly diagnosed tears, but data are currently lacking. Methods: Sixty-one patients with 38 partial and 23 full-thickness tears of 1 shoulder at arthroscopy were examined with bilateral radiographs, ultrasound, and the Constant-Murley score at a mean of 22 years (range, 21-25 years) after arthroscopy. Results: The overall rate of full-thickness tears in the contralateral shoulder was 50.8%. In patients with a full-thickness tear and CTA (Hamada grade amp;gt;= 2) in the index shoulder at follow-up, 18 of 20 (90%) had a contralateral full-thickness tear and 4 of 20 (20%) had CTA. In patients with a partial tear in the index shoulder at follow-up, 3 of 22 (13.6%) had a contralateral full-thickness tear and none had CTA. CTA changes were more common in patients with FTT and a previous acromioplasty (P amp;lt; .001). The correlation between shoulders was 0.72 for the number of tendons with FTT (P amp;lt; .001), 0.31 for the Hamada grade (P = .016), and 0.65 for the absolute Constant-Murley score (P amp;lt; .001). The number of tendons with a full-thickness tear at follow-up was a risk factor (odds ratio, 3.28; 95% confidence interval, 1.67-6.44; P amp;lt; .001) for a contralateral full-thickness tear. Patients with a partial or full-thickness tear in the contra-lateral shoulder had pain in 39.2% of cases. Conclusion: Patients with long-standing cuff tears have high rates of contralateral cuff tears. The severity of the condition is strongly correlated between the shoulders. Patients with full-thickness tears and a previous acromioplasty have a significantly higher frequency of CTA than patients with cuff tears who had not undergone a previous acromioplasty.

    Post-traumatic stiff elbow2018Ingår i: EFORT open reviews, ISSN 2058-5241, Vol. 3, nr 5, s. 210-216Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Post-traumatic and post-operative stiffness of the elbow joint is relatively common and may in pronounced cases markedly interfere with normal upper extremity function.Soft-tissue contractures and heterotopic bone formation are two major causes of limited movement.Extensive recent research has elucidated many of the pathways contributing to these conditions, but the exact mechanisms are still unknown.In the early phase of soft-tissue contractures conservative treatment may be valuable, but in longstanding cases operative treatment is often necessary.Several different options are available depending on the severity of the condition and the underlying offending structures. Surgical treatment may allow significant gains in movement but rarely complete restoration, and complications are not uncommon.The following presentation reviews the recent literature on pathomechanisms and treatment alternatives.

    Tensioning of the radioscaphocapitate and long radio-lunate ligaments for dynamic radiocarpal instability2018Ingår i: Journal of Hand Surgery, European Volume, ISSN 1753-1934, E-ISSN 2043-6289, Vol. 43, nr 4, s. 369-374Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    During 1994-2003, we treated 20 patients with post-traumatic radial-sided wrist pain and dynamic radiocarpal instability. After arthroscopy confirmed no disruption of the radioscaphocapitate ligament and an increased laxity of the ligament, we passed a strip of the radioscaphocapitate ligament through the long radio-lunate ligament. The rationale of this procedure was to increase tension of the two ligaments and to close the space of Poirier. Eighteen patients were assessed after 1-3.7 years (mean 2.5 years). Four patients were symptom-free and 11 patients were markedly improved. Fourteen patients were followed for 11-15 years; four patients were symptom-free and eight patients were markedly improved. Two reported unchanged symptoms and none was worse in the follow-up. Based on our findings, we suggest a cause of post-traumatic radial-sided wrist pain is laxity of the radiocarpal joint. We conclude that our surgical procedure increases tension in the radioscaphocapitate and long radio-lunate ligaments and decreases wrist pain at rest and during activity. Level of Evidence: IV

    A radial head prosthesis appears to be unnecessary in Mason-IV fracture dislocation2017Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 88, nr 3, s. 315-319Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose - Previous reports on elbow injuries with concomitant comminute radial head fracture are difficult to interpret, since they include an array of different soft-tissue and bony injuries around the elbow. We focused on Mason-IV fracture dislocations of the elbow and retrospectively reviewed 2 treatment options: radial head resection or replacement with a radial head arthroplasty, both in combination with lateral ligament repair. Patients and methods - In Linkoping, 18 consecutive patients with Mason-IV fracture dislocation and with a median age of 56 (19-79) years were treated with a radial head arthroplasty. In Malmo, 14 consecutive patients with a median age of 50 (29-70) years were treated for the same injury with radial head resection. With a follow-up of at least 2 years (Linkoping: median 58 months; Malmo: median 108 months), the outcome was assessed using the Mayo elbow performance score (MEPS), the Disabilities of Arm, Shoulder, and Hand questionnaire (DASH), range of movement, instability, and plain radiographs. Results - There was no statistically significant difference between the groups regarding MEPS, DASH, or range of motion. The rate of additional surgery was higher in patients treated with arthroplasty. Ulno-humeral osteoarthritis was more pronounced in the group treated with radial head resection, but the follow-up time was longer in these patients. Functional results and range of motion tally well with previous reports on similar injuries. Interpretation - Functional results did not improve by using a press-fit radial head arthroplasty in Mason-IV fracture dislocation of the elbow. Secondary osteoarthritis after resection of the radial head is a concern, but it did not affect the functional outcome during the follow-up time.

    A short activity-related scale for measuring shoulder function in patients with subacromial pain: the DASH 72017Ingår i: JSES Open Access, ISSN 2468-6026, Vol. 1, nr 2, s. 113-118Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Subacromial pain is a common cause of shoulder dysfunction that negatively affects quality of life. Currently, most outcome measures for shoulder pain are applied to a heterogeneous group of patients. Of these measures, the Disabilities of the Arm, Shoulder, and Hand (DASH) is the most widely recognized test with which to assess patients with subacromial pain. The primary aim of this study was to assess the content validity of DASH for patients with subacromial pain, with a secondary aim to test responsiveness to a modified set of DASH items tailored to these patients. Methods There were 129 patients who reported activities in the Patient-Specific Functional Scale (PSFS). To assess validity, 5 independent physiotherapists matched PSFS activities to the most appropriate DASH item. DASH items identified as being of greatest importance to patients were those corresponding to the highest number of PSFS-matched activities. Calculations were made for responsiveness and internal consistency. Results Physiotherapists matched DASH items to 271 PSFS activities, reaching agreement for almost 80%. Seven DASH items (DASH 7) were identified as being particularly important. Effect size data (Cohen's d) were 0.93 for DASH 7, 0.92 for DASH 30, and 0.85 for QuickDASH; the corresponding Cronbach's α values (for DASH 7, DASH 30, and QuickDASH) were 0.84, 0.94, and 0.86, respectively. Conclusions DASH 7 is a short, patient-centered, and activity-related scale that can measure shoulder function in patients with subacromial pain using a quarter of the original DASH items. DASH 7 demonstrated responsiveness, with a satisfactory level of internal consistency.

    Association of Insulin-like Growth Factor-1, Bone Mass and Inflammation to Low-energy Distal Radius Fractures and Fracture Healing in Elderly Women Attending Emergency Care2017Ingår i: ORTHOPAEDIC SURGERY, ISSN 1757-7853, Vol. 9, nr 4, s. 380-385Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective

    Elderly patients suffer fractures through low-energy mechanisms. The distal radius is the most frequent fracture localization. Insulin-like growth factor-1 (IGF1) plays an important role in the maintenance of bone mass and its levels decline with advancing age and in states of malnutrition. Our aim was to investigate the association of IGF1 levels, bone mass, nutritional status, and inflammation to low-energy distal radius fractures and also study if fracture healing is influenced by IGF1, nutritional status, and inflammation.

    Methods

    Postmenopausal women, 55 years or older, with low-energy distal radius fractures occurring due to falling on slippery ground, indoors or outdoors, were recruited in the emergency department (ED) and followed 1 and 5 weeks after the initial trauma with biomarkers for nutritional status and inflammation. Fractures were diagnosed according to standard procedure by physical examination and X-ray. All patients were conservatively treated with plaster casts in the ED. Patients who needed interventions were excluded from our study. Fracture healing was evaluated from radiographs. Fracture healing assessment was made with a five-point scale where the radiological assessment included callus formation, fracture line, and stage of union. Blood samples were taken within 24 h after fracture and analyzed in the routine laboratory. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DXA).

    Results

    Thirty-eight Caucasian women, aged 70.5 8.9 years (mean +/- SD) old, were recruited. Nutritional status, as evaluated by albumin (40.3 +/- 3.1 g/L), IGF1 (125.3 +/- 39.9 g/L), body mass index (26.9 +/- 3.6 kg/m(2)), arm diameter (28.9 +/- 8.9 cm), and arm skinfold (2.5 +/- 0.7 cm), was normal. A positive correlation was found between IGF1 at visit 1 and the lowest BMD for hip, spine, or radius (r = 0.39, P = 0.04). High sensitive C-reactive protein (hsCRP) and leukocytes were higher at the fracture event compared to 5 weeks later (P = 0.07 and P amp;lt; 0.001, respectively). Fracture healing parameters (i.e. callus formation, fracture line, and stage of union) were positively correlated with the initial leukocyte count and to difference in thrombocyte count between visit 1 and 3.

    Conclusions

    In elderly women with low-energy distal radius fractures, an association between IGF1 and lowest measures of BMD was found, indicating that low IGF1 could be an indirect risk factor for fractures. Fracture healing was associated with initial leukocytosis and a lower thrombocyte count, suggesting that inflammation and thrombocytes are important components in fracture healing.

    Clinical and structural outcome 22 years after acromioplasty without tendon repair in patients with subacromial pain and cuff tears2017Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 26, nr 7, s. 1262-1270Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Long-term results regarding tear progression, arthropathy, and clinical scores of unrepaired rotator cuff tears are largely unknown. This study investigated whether the condition of the glenohumeral joint and rotator cuff had deteriorated at a minimum of 20 years after an acromioplasty without cuff repair and assessed the clinical results. Methods: A retrospective analysis was conducted of a consecutive series of patients treated between 1989 and 1993 with acromioplasty without cuff repair due to subacromial pain and cuff tear. At follow-up results of x-ray, ultrasonography, and clinical scores were recorded. Results: At a mean of 22 years (range, 21-25 years), 69 patients were available for follow-up with Western Ontario Rotator Cuff Index, Constant-Murley (CM) score, x-ray, and ultrasonography. Mean age at operation was 49 years (range, 19-69 years). There were 45 partial-thickness tears (PTT) and 24 full-thickness tears (FTT). Of 23 patients with FTT, 17 (74% with x-ray) had developed cuff tear arthropathy (Hamada amp;gt;= 2) and 20 (87% with ultrasonography) had progressed in tear size. Mean relative CM in patients with FTT and cuff tear arthropathy was 62 (standard deviation [SD], 27), and the mean WORC was 58% (SD, 26%). In the 43 PTT patients, 3 (7% with x-ray) had developed cuff tear arthropathy and 16 (42% with ultrasonography) had tear progression. With PTT at follow-up, the mean relative CM was 101 (SD, 22), and the mean WORC was 81% (SD, 20%). Conclusions: After an acromioplasty, most unrepaired full-thickness tears will, in long-term, increase in size and be accompanied by cuff tear arthropathy changes. Most partial thickness tears remain unchanged; cuff tear arthropathy is rare, and clinical scores generally good. (C) 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

    Extensive soft tissue lesions in redislocated after simple elbow dislocations2017Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 26, nr 7, s. 1294-1297Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The majority of simple elbow dislocations (no associated fractures) can be treated nonoperatively with a short period of immobilization followed by guided aftercare. This case series describes the soft tissue injuries in a rare subset of patients in whom the elbow redislocated despite adequate immobilization. Methods: During a 6-year period, 8 patients were identified. They were all treated with reduction and casting in 90 degrees of flexion or more. At 1 week of follow-up, redislocation had occurred in all patients and open soft tissue repair was performed. The injuries were documented and the patients were followed up clinically and with radiographs. Results: Extensive soft tissue injuries, including both collateral ligament injuries and muscle origin avulsions from either or both sides, were found in all patients. The functional result at follow-up was satisfactory in all patients. Conclusion: Vast soft tissue injuries including both collateral ligaments and muscle origins should be expected in the event of early severe instability of a dislocated elbow joint.

    Specific exercises for subacromial pain: Good results maintained for 5 years2017Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 88, nr 6, s. 600-605Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose — We have previously shown that specific exercises reduced the need for surgery in subacromial painpatients at 1-year follow-up. We have now investigated whetherthis result was maintained after 5 years and compared the outcomesof surgery and non-surgical treatment.Patients and methods — 97 patients were included in the previouslyreported randomized study of patients on a waiting list forsurgery. These patients were randomized to specifi c or unspecifi cexercises. After 3 months of exercises the patients were asked ifthey still wanted surgery and this was also assessed at the present5-year follow-up. The 1-year assessment included Constant–Murley score, DASH, VAS at night, rest and activity, EQ-5D, andEQ-VAS. All these outcome assessments were repeated after 5years in 91 of the patients.Results — At the 5-year follow-up more patients in the specifi cexercise group had declined surgery, 33 of 47 as compared with16 of 44 (p = 0.001) in the unspecifi c exercise group. The meanConstant–Murley score continued to improve between the 1- and5-year follow-ups in both surgically and non-surgically treatedgroups. On a group level there was no clinically relevant changebetween 1 and 5 years in any of the other outcome measuresregardless of treatment.Interpretation — This 5-year follow-up of a previously publishedrandomized controlled trial found that specifi c exercisesreduced the need for surgery in patients with subacromial pain.Patients not responding to specifi c exercises may achieve similargood results with surgery. These fi ndings emphasize that a specifi cexercise program may serve as a selection tool for surgery.

    Subjective ulnar nerve dysfunction commonly following open reduction, internal fixation (ORIF) of distal humeral fractures and in situ decompression of the ulnar nerve2017Ingår i: Strategies in trauma and limb reconstruction (Online), ISSN 1828-8928, Vol. 12, nr 1, s. 19-25Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this retrospective study was to investigate the frequency of persistent ulnar affection in patients who underwent open reduction and internal fixation (ORIF) of distal humeral fractures without ulnar nerve transposition or mobilisation. Eighty-two patients (53 women), mean age 62 years, were, at a mean of 48 months, reviewed through medical records and a subjective evaluation form concerning ulnar nerve problems. Ulnar nerve affliction, in most cases regarded as mild, was experienced by 22 patients (27%; 14 women) and significantly associated with multiple surgeries. Three patients had been operated with late neurolysis and one with transposition without reported improvement. The proportion of ulnar nerve dysfunction was equally common regardless of medial or lateral plating. ORIF with plate fixation and without ulnar nerve transposition seems to be an acceptable option for patients with distal humeral fractures. The frequency of ulnar nerve affection in our series does not appear higher than previously reported. Subjective ulnar nerve symptoms were, however, relatively common and appear related to the trauma itself, the surgery, or the post-operative management which highlights the need for further analysis of these factors.

    Transclavicular Osseous Sutures for the Treatment of Displaced Distal Clavicular Fractures in Children2016Ingår i: Journal of Orthopaedic Trauma, ISSN 0890-5339, E-ISSN 1531-2291, Vol. 30, nr 5, s. E181-E185Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We describe a novel surgical technique for the treatment of displaced distal clavicular fractures in children. These fractures are rare, and recommendations on treatment vary. Conservative treatment might lead to persistent deformity and limitations of function. Previous reports of surgical treatment involve fracture fixation with K-wires. This requires a routine sequential reoperation to remove the implant and has been associated with serious complications in some patients. The surgical technique described here is based on osseous sutures through the clavicular shaft and coracoclavicular ligaments and is found successful for the treatment of distal clavicular fractures in children and may also be feasible for true acromioclavicular dislocations. The main principle of the technique is a fixation of the displaced clavicle through transclavicular drill holes, against the intact inferior periosteal sleeve at the insertion of the coracoclavicular ligaments. No temporary K-wire fixation is needed. To date, we have treated 7 patients with this technique. All fractures healed uneventfully with an excellent functional result and without skeletal deformity.

    Hemiarthroplasty for irreparable distal humeral fractures: Medium-term follow-up of 42 patients2015Ingår i: The Bone & Joint Journal, ISSN 2049-4394, E-ISSN 2049-4408, Vol. 97B, nr 10, s. 1377-1384Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We report our experience of performing an elbow hemiarthroplasty in the treatment of comminuted distal humeral fractures in the elderly patients. A cohort of 42 patients (three men and 39 women, mean age 72; 56 to 84) were reviewed at a mean of 34.3 months (24 to 61) after surgery. Functional outcome was measured with the Mayo Elbow Performance Score (MEPS) and range of movement. The disabilities of the arm, shoulder and hand questionnaire (DASH) was used as a patient rated evaluation. Complications and ulnar nerve function were recorded. Plain radiographs were obtained to assess prosthetic loosening, olecranon wear and heterotopic bone formation. The mean extension deficit was 23.5 degrees (0 degrees to 60 degrees) and mean flexion was 126.8 degrees (90 degrees to 145 degrees) giving a mean arc of 105.5 degrees (60 degrees to 145 degrees). The mean MEPS was 90 (50 to 100) and a mean DASH score of 20 (0 to 63). Four patients had additional surgery for limited range of movement and one for partial instability. One elbow was revised due to loosening, two patients had sensory ulnar nerve symptoms, and radiographic signs of mild olecranon wear was noted in five patients. Elbow hemiarthroplasty for comminuted intra-articular distal humeral fractures produces reliable medium-term results with functional outcome and complication rates, comparable with open reduction and internal fixation and total elbow arthroplasty.

    Non-union in 3 of 15 osteotomies of the distal radius without bone graft2015Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 86, nr 3, s. 316-320Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose - Open-wedge osteotomies of the distal radius create a void that is usually filled with either iliac crest bone graft or bone substitute. Previous studies have suggested that this is unnecessary. We investigated the safety of omitting the filling procedure. Patients and methods - We included 15 patients with a dorsal malunion of a distal radius fracture. A palmar approach and angle-stable plates were used. The patients were followed until there was radiographic and clinical healing. Results - Non-union occurred in 3 of the 15 patients. The study, which had been planned to include 25 patients, was then discontinued. 6 osteotomies created a trapezoid void (no cortical contact); 3 of these did not unite after the index procedure (p = 0.04), but did subsequently, after autogenous bone grafting. A trapezoid void was significantly associated with non-union (p = 0.04). Interpretation - When a trapezoid defect is created, one should consider bone substitute or autogenous bone graft. This has been shown to be safe in other studies.

    A specific exercise strategy reduced the need for surgery in subacromial pain patients2014Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 48, nr 19, s. 1431-1436Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose A programme based on eccentric exercises for treating subacromial pain was in a previous study found effective at 3-month follow-up. The purposes of the present study were to investigate whether the results were maintained after 1 year and whether the baseline Constant-Murley score, rotator cuff status and radiological findings influenced the outcome. Patients and methods 97 patients on the waiting list for arthroscopic subacromial decompression had been randomised to a specific exercise programme or unspecific exercises (controls). After 3 months of exercises, the patients were asked whether they still wanted surgery and this option was available until a 1-year follow-up. 1 year after inclusion or 1 year after surgery, the number of patients who decided to have surgery in each group was compared. The choice of surgery was related to the baseline Constant-Murley score, ultrasound and radiographs taken at inclusion. Results All patients had improved significantly (pless than0.0001) in the Constant-Murley score at the 1-year follow-up. Significantly more patients in the control group decided to have surgery (63%) than those in the specific exercise group (24%; pless than0.0001). Patients who decided to have surgery had a significantly lower baseline Constant-Murley score and more often a full-thickness tear. Patients with partial tears did not differ from those with intact tendons. Interpretation The positive short-term results of specific exercises were maintained after 1 year, and this exercise strategy reduces the need for surgery. Full-thickness tear and a low baseline Constant-Murley score appear to be a predictive marker for a less good outcome.

    Minimal important changes in the Constant Murley score in patients with subacromial pain2014Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 23, nr 8, s. 1083-1090Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The purpose of this study was to determine the minimal important change (MIC) of improvement in the Constant‐Murley score (CM score) in patients with longstanding subacromial pain and in subgroups of patients with subacromial pain with and without rotator cuff ruptures.

    Method: The MIC was estimated by using the visual anchor‐based MIC distribution method, which integrates an anchor‐ and distribution‐based approach: the optimal cut‐off point of the receiver operator characteristic curve (MIC ROC) and the 95% limit cut‐ off point (MIC 95%limit). The study population consisted of 93 patients included in a randomized clinical trial evaluating the effect of a specific exercise strategy in patients with longstanding subacromial pain.

    Results: The MIC ROC was found at a mean change of 17 points in the CM score. The MIC 95% limit was found at a mean change of 24 points. In the subgroup analysis the MIC ROC was found at a mean change of 19 points and the MIC 95% limit at 18 points in patients with an intact rotator cuff. In patients with rotator cuff ruptures the MIC ROC was found at a mean change of 15 points and the MIC 95% limit at 30 points.

    Conclusion: The CM score is able to detect the minimal important change in individual patients with long‐standing subacromial pain when the rotator cuff is intact. In all patients with longstanding subacromial pain, the MIC value was dependent on the subgroup as well as the choice of statistical analysis. The estimated MIC values could be used as an indication for relevant changes in the CM score in clinical practice and guide the clinician in how to interpret the results of specific treatments for patients with longstanding subacromial pain.

    Study question

    Can a specific exercise strategy improve shoulder function and pain in patients with subacromial impingement syndrome, thereby decreasing the need for arthroscopic subacromial decompression?

    Summary answer

    Compared with a control exercise group, patients in the specific exercise group had significantly greater improvements in shoulder function and pain and fewer patients needed surgery at the three month assessment.

    What is known and what this paper adds

    Different exercise programmes are used as first line treatment in patients with subacromial impingement syndrome, but conclusive evidence to support the efficacy for these programmes is lacking. This specific exercise strategy proved effective in improving shoulder function and pain in patients in whom earlier conservative treatment had failed.

    Effect of specific exercise strategy on need for surgery in patients with subacromial impingement syndrome: randomised controlled study2012Ingår i: BMJ. British Medical Journal, ISSN 0959-8146, E-ISSN 0959-535X, Vol. 344, s. e787-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To evaluate if a specific exercise strategy, targeting the rotator cuff and scapula stabilisers, improves shoulder function and pain more than unspecific exercises in patients with subacromial impingement syndrome, thereby decreasing the need for arthroscopic subacromial decompression.

    DESIGN: Randomised, participant and single assessor blinded, controlled study.

    SETTING: Department of orthopaedics in a Swedish university hospital.

    PARTICIPANTS: 102 patients with long standing (over six months) persistent subacromial impingement syndrome in whom earlier conservative treatment had failed, recruited through orthopaedic specialists.

    INTERVENTIONS: The specific exercise strategy consisted of strengthening eccentric exercises for the rotator cuff and concentric/eccentric exercises for the scapula stabilisers in combination with manual mobilisation. The control exercise programme consisted of unspecific movement exercises for the neck and shoulder. Patients in both groups received five to six individual guided treatment sessions during 12 weeks. In between these supervised sessions the participants performed home exercises once or twice a day for 12 weeks.

    MAIN OUTCOME MEASURES: The primary outcome was the Constant-Murley shoulder assessment score evaluating shoulder function and pain. Secondary outcomes were patients' global impression of change because of treatment and decision regarding surgery.

    RESULTS: Most (97, 95%) participants completed the 12 week study. There was a significantly greater improvement in the Constant-Murley score in the specific exercise group than in the control exercise group (24 points (95% confidence interval 19 to 28.0) v 9 points (5 to 13); mean difference between group: 15 points (8.5 to 20.6)). Significantly more patients in the specific exercise group reported successful outcome (defined as large improvement or recovered) in the patients' global assessment of change because of treatment: 69% (35/51) v 24% (11/46); odds ratio 7.6, 3.1 to 18.9; P<0.001. A significantly lower proportion of patients in the specific exercise group subsequently chose to undergo surgery: 20% (10/51) v 63% (29/46); odds ratio 7.7, 3.1 to 19.4; P<0.001).

    CONCLUSION: A specific exercise strategy, focusing on strengthening eccentric exercises for the rotator cuff and concentric/eccentric exercises for the scapula stabilisers, is effective in reducing pain and improving shoulder function in patients with persistent subacromial impingement syndrome. By extension, this exercise strategy reduces the need for arthroscopic subacromial decompression within the three month timeframe used in the study.

    Elevated plasma levels of TIMP-1 in patients with rotator cuff tear2012Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 83, nr 5, s. 523-528Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose:Extracellular matrix remodelling is altered in rotator cuff tears,16partly due to altered expression of matrix metalloproteinases (MMPs) and their inhibitors. It is unclear if this altered expression can be traced as changes in plasma protein levels.

    The purposes were to measure the plasma level of MMPs and their tissue inhibitors (TIMPs) inpatients with rotator cuff tears and to relate changes in the pattern of MMP and TIMP levels with the extent of the rotator cuff tear.

    Methods: Blood samples were collected from 17 patients, median 61 (range 39-77) years, with sonographically verified rotator cuff tears (partial- or full-thickness). These were compared with 16 gender and age matched control persons with sonographically intact rotator cuffs. Plasma levels of MMPs and TIMPs were measured simultaneously using Luminex technology and ELISA.

    Results: The plasma level of TIMP-1 was elevated in patients with rotator cuff tears, especially in those with full-thickness tears. The levels of TIMP-1, TIMP-3 and MMP-9 were higher in patients with full-thickness tears compared to those with partial-thickness tears, but only TIMP-1 was different from controls.

    Interpretation: The observed elevation of TIMP-1 in plasma might reflect local pathological processes in or around the rotator cuff, or a genetic predisposition in these patients. That levels of TIMP-1 and certain MMP´s was found to differ between partial and full thickness tears may reflect the extent of the lesion or different aetiology and pathomechanisms.

    Medial epicondylalgia (golfer’s elbow) treated by eccentric exercise2012Ingår i: Shoulder & Elbow, ISSN 1758-5732, Vol. 4, nr 1, s. 50-55Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Eccentric exercises have been successfully used in the treatment of Achilles and patellar tendinopathies, as well as lateral epicondylalgia. No studies have explored the same treatment for medial epicondylalgia (golfer’s elbow).

    Methods: Twenty consecutive adults with a clinical diagnosis of medial epicondylalgia were treated with eccentric exercise over 3 months in this prospective case series. The programme was based on home training. There were 11 women and nine men, with a mean age of 47 years, and a mean duration of symptoms of 19 months. At baseline, at 3 months and after a mean of 11 years, pain was assessed by three independent visual analogue scales (VAS) and grip strength using a Jamar dynamometer (Sammons Preston Inc., Jackson, MI, USA). At the 11-year follow-up, patients also reported their satisfaction on a 100-mm VAS and completed the Disabilities of Arm, Shoulder and Hand questionnaire.

    Results: Pain decreased significantly in all measured variables at both assessment occasions (all p < 0.0001). Grip strength in the affected arm/hand increased significantly after 3 months (p = 0.009).

    Discussion: Twelve weeks of eccentric training reduced pain and increased grip strength in patients with medial epicondylalgia. It is a safe, uncomplicated and cost-effective method, with only a minimum contribution from a physiotherapist.

    Patterns of triangular fibrocartilage complex (TFCC) injury associated with severely dorsally displaced extra-articular distal radius fractures2012Ingår i: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 43, nr 6, s. 926-932Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: The aim of the study was to examine triangular fibrocartilage (TFCC) injury patterns associated with unstable, extra-articular dorsally displaced distal radius fractures.

    Methods: Twenty adult patients with an Arbeitsgemeinschaft für Osteosynthesefragen (AO), type A2 or A3, distal radius fracture with an initial dorsal angulation greater than 20° were included. Nine had a tip fracture (distal to the base) of the ulnar styloid and 11 had no such fracture. They were all openly explored from an ulnopalmar approach and TFCC injuries were documented. Eleven patients also underwent arthroscopy and intra-articular pathology was recorded.

    Results: All patients had TFCC lesions of varying severity, having an extensor carpi ulnaris subsheath avulsion in common. Eighteen out of 20 also displayed deep foveal radioulnar ligament lesions, with decreasingly dorsal fibres remaining. The extent of this foveal injury could not be appreciated by radiocarpal arthroscopy.

    Conclusions: Severe displacement of an extra-articular radius fracture suggests an ulnar-sided ligament injury to the TFCC. The observed lesions concur with findings in a previous cadaver study. The lesions follow a distinct pattern affecting both radioulnar as well as ulnocarpal stabilisers.

    The Kudo humeral component as primary hemiarthroplasty in distal humeral fractures2012Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 21, nr 4, s. 451-455Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Treatment of intra-articular fractures of the distal humerus in the elderly is challenging. In patients with very distal fractures and severe comminution, primary arthroplasty has been advocated. Recently, a few reports have described promising results of hemiarthroplasty. This study describes the medium-term results of using the Kudo humeral implant (Biomet Ltd, Bridgend, U. K.) as replacement of the distal humerus. less thanbrgreater than less thanbrgreater thanMaterial and methods: Eight women (mean age, 79 years) were treated. Follow-up was conducted at a mean of 4 years after the procedure and consisted of the Mayo Elbow Performance Score (MEPS), radiographic images, and range of motion (ROM). less thanbrgreater than less thanbrgreater thanResults: All patients had a good or excellent outcome according to the MEPS. Mean ROM was 31 degrees to 126 degrees. Radiographic signs of attrition of the ulna were observed in 3 patients but did not correlate with the functional outcome. A periprosthetic fracture occurred in 1 patient 3 years after the index operation, and ROM was unsatisfactory in 1 patient. No other complications were observed. less thanbrgreater than less thanbrgreater thanConclusion: The use of the Kudo humeral implant as a hemiarthroplasty resulted in a reasonable functional outcome in the medium-term, but the radiographic signs of attrition suggest that the implant is not recommended as a hemiprosthesis.

    Arthroscopic Synovectomy of the Wrist2011Ingår i: Hand Clinics, ISSN 0749-0712, E-ISSN 1558-1969, Vol. 27, nr 3, s. 395-399Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Arthroscopic synovectomy is safe and reliable, with mild postoperative morbidity. The rationale of a surgical synovectomy is to excise inflamed synovium and thereby, remove as much effusion and inflammatory substrate as possible. In most cases, arthroscopic synovectomy is performed as an outpatient procedure. The technique has also been used for other diagnoses causing wrist arthritis, but very few results have been reported and the indications remain to be defined. In rheumatoid arthritis (RA), juvenile chronic arthritis (JCA), systemic lupus erythematosus (SLE), and post-infectious monoarthritis, a long period of increased comfort and improved function can be anticipated.

    Pathomechanisms of ulnar ligament lesions of the wrist in a cadaveric distal radius fracture model2011Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 82, nr 3, s. 360-364Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose: Mechanisms of injury to ulnar sided ligaments, stabilizing the distal radioulnar joint and the ulna to the carpus, associated with dorsally displaced distal radius fractures are poorly described. We investigated the injury patterns in a human cadaver fracture model.

    Methods: Fresh frozen human cadaver arms were used. A dorsal open wedge osteotomy was made in the distal radius. In 8 specimens pressure was applied to the palm with the wrist in dorsiflexion and ulnar sided stabilizing structures subsequently severed. Dorsal angulation was measured on digitized radiographs. In 8 more specimens the triangular fibrocartilage complex was forced into rupture by axially loading the forearm with the wrist in dorsiflexion. The ulnar side was dissected and injuries were recorded.

    Results: Intact ulnar soft tissues limited the dorsal angulation of the distal radius fragment to a median of 32o (16-34o). A combination of bending and shearing of the distal radius fragment was needed to create TFCC injuries. Both palmar and dorsal injuries were observed simultaneously in 6/8 specimens.

    Interpretation: A TFCC injury can be expected when dorsal angulation of a distal radius fracture exceeds 32o. The extensor carpi ulnaris subsheath may be a functionally integral part of the TFCC. Both dorsal and palmar structures can tear simultaneously. These findings may have implications for reconstruction of ulnar sided soft tissue injuries.

    Patient-reported outcome of surgical treatment of nerve entrapments in the proximal forearm2011Ingår i: Advances in orthopedics, ISSN 2090-3472, Vol. 2011, s. 727689-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The outcome of decompression for long-standing symptoms of nerve entrapments in the proximal forearm was investigated in a retrospective study of 205 patients using a self-assessment questionnaire, 45 months after the operation. The questionnaire consisted of visual analogue scale recordings of pre- and postoperative pain during rest and activity, questions about remaining symptoms and appreciation of the result and the Disabilities of Arm, Shoulder and Hand form (DASH). Altogether, 59% of the patients were satisfied, 58% considered themselves improved, and 3% as being entirely relieved of all symptoms. Pain decreased significantly (P = 0.001). There was a significant correlation between preoperative duration and patient perceived post-operative pain. Preoperative pain was a chief complaint, and pain reduction appears to be the principal gain of the operation. Although the majority of the patients benefited from the operation, a substantial proportion was not satisfied. There is apparently room for improvement of the diagnostic and surgical methods applied in this study.

    Radioulnar laxity and clinical outcome after a distal radius fracture do not correlate after a distal radius fracture2011Ingår i: Journal of Hand Surgery - British and European Volume, ISSN 0266-7681, E-ISSN 1532-2211, Vol. 36, nr 6, s. 503-508Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Injury to the triangular fibrocartilage complex associated with distal radius fracture may cause symptoms of ulnar instability. Assessed by a radioulnar stress test, increased laxity of the distal radio-ulnar joint has in two previous studies been depicted to be associated with poorer outcome. This prospective study of 40 adults investigates the correlation of this test with functional outcome as measured by DASH. No clinically significant difference was found in relation to this test at two and five years after injury. Therefore using this test alone to decide whether or not to perform an acute repair of the TFCC cannot be recommended.

    The influence of age, delay of repair, and tendon involvement in acute rotator cuff tears Structural and clinical outcomes after repair of 42 shoulders2011Ingår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 82, nr 2, s. 187-192Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and purpose Few authors have considered the outcome after acute traumatic rotator cuff tears in previously asymptomatic patients. We investigated whether delay of surgery, age at repair, and the number of cuff tendons involved affect the structural and clinical outcome. Patients and methods 42 patients with pseudoparalysis after trauma and no previous history of shoulder symptoms were included. A full-thickness tear in at least 1 of the rotator cuff tendons was diagnosed in all patients. Mean time to surgery was 38 (6-91) days. Follow-up at a mean of 39 (12-108) months after surgery included ultrasound, plain radiographs, Constant-Murley score, DASH score, and western Ontario rotator cuff (WORC) score. Results At follow-up, 4 patients had a full-thickness tear and 9 had a partial-thickness tear in the repaired shoulder. No correlation between the structural or clinical outcome and the time to repair within 3 months was found. The patients with a tendon defect at follow-up had a statistically significantly lower Constant-Murley score and WORC index in the injured shoulder and were significantly older than those with intact tendons. The outcomes were similar irrespective of the number of tendons repaired. Interpretation A delay of 3 months to repair had no effect on outcome. The patients with cuff defects at follow-up were older and they had a worse clinical outcome. Multi-tendon injury did not generate worse outcomes than single-tendon tears at follow-up.

    Fewer rotator cuff tears fifteen years after arthroscopic subacromial decompression2010Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 19, nr 1, s. 111-115Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: A successful clinical result is reported in 75% to 85% of impingement patients after arthroscopic subacromial decompression. The result is maintained over time, but few studies have investigated the integrity of the rotator cuff in these patients. Materials and methods: Using ultrasonography, we examined the integrity of the rotator cuff in 70 patients 15 years after arthroscopic subacromial decompression. All patients had an intact rotator cuff at the index procedure. Results: Tendons were still intact in 57 patients (82%), 10 (14%) had partial-thickness tears, and 3 (4%) had full-thickness tears. Discussion: The total number of 18% tears (partial and full thickness) in this study, including patients clinically diagnosed with subacromial impingement at a mean age of 60 years, is unexpectedly low compared with 40% degenerative tears reported in asymptomatic adults of the same age. Conclusion: Arthroscopic subacromial decompression seems to reduce the prevalence of rotator cuff tears in impingement patients. This appears attributable to elimination of extrinsic factors such as mechanical wear and bursitis. The potential effect of surgery on intrinsic cuff degeneration is unknown, but intrinsic factors may explain tears still developing despite decompression.

    Radioulnar ratio in detection of distal radioulnar joint instability associated with acute distal radius fractures2010Ingår i: JOURNAL OF HAND SURGERY (EUROPEAN VOLUME), ISSN 1753-1934, Vol. 35E, nr 9, s. 730-734Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Lesions of the triangular fibrocartilage complex (TFCC) are commonly associated with distal radius fractures and may adversely affect the functional outcome. This prospective study evaluated computed tomography, using the radioulnar ratio (RUR), to detect laxity of the distal radioulnar joint in 48 consecutive patients with acute distal radius fractures and compared the results with a radioulnar stress test. We found the clinical stress test to be reliable in chronic cases, but the RUR method of questionable value in both acute and chronic cases.

    Conservative treatment of the cubital tunnel syndrome2009Ingår i: Journal of Hand Surgery: European Volume, ISSN 1753-1934, Vol. 34, nr 2, s. 201-207Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Conservative treatment of the cubital tunnel syndrome was evaluated in a randomised study of 70 patients with mild or moderate symptoms (Dellon, 1989). All patients were informed about the cause of symptoms and allocated to three groups: night splinting, nerve gliding and control. Evaluation consisted of Canadian Occupational Performance Measure, visual analogue pain scales, strength measurements and neurophysiological examination, before treatment and after six months. Fifty-seven patients were followed for six months. Fifty-one (89.5%) were improved at the follow-up. There were no significant differences between the groups in any of the recorded variables. Night splints and nerve gliding exercises did not add favourably. Routine neurophysiological examination seems unnecessary since 76% of the patients with typical symptoms had normal findings and 75% with pathological findings improved. Patients with mild or moderate symptoms have a good prognosis if they are informed of the causes of the condition and how to avoid provocation.

    Tricalcium phosphate bone substitute in corrective osteotomy of the distal radius2009Ingår i: INJURY-INTERNATIONAL JOURNAL OF THE CARE OF THE INJURED, ISSN 0020-1383, Vol. 40, nr 3, s. 262-267Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To evaluate the outcome of using tricalcium phosphate (TCP) as void filler and structural support in corrective opening-wedge osteotomy of the distal radius.

    Methods: A consecutive series of 17 patients with malunited dorsally angulated distal radius fracture postoperatively with DASH at 6 months with radiography at 8-12 weeks and 0.5-3.5 years.

    Results: Mean DASH score improved from 52 (S.D. 22) preoperatively to 30 (S.D. 22) postoperatively. There was one non-union. There was also a mean loss of radial length of 1.1 mm (S.D. 1.0 mm) between the first postoperative radiograph and final follow-up. Radiolucent zones were observed around the TCP grafts after 6-8 weeks in 10/14 cases, but could not be statistically correlated with the slight loss of reduction.

    Conclusions: TCP seems to be an alternative to iliac crest bone grafting in corrective osteotomies of the distal radius. The shortening observed over time may be attributable to inflammation induced by the TCP.

    Small full-thickness tears do well ten to thirteen years after arthroscopic subacromial decompression2008Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 17, nr 1 SUPPL.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A consecutive series of 181 patients with clinical signs of subacromial impingement underwent arthroscopic subacromial decompression (ASD). All patients had the same surgical procedure, and all pathological findings at the arthroscopy were recorded. Ten to 13 years (mean, 11.2) after the procedure, 162 patients (91%) were available for follow-up consisting of clinical examination and the Constant-Murley and DASH scores. The overall mean value of the age correlated Constant score was 77 points. Men had significantly better Constant score than women. The state of the rotator cuff at the index procedure was found to affect the outcome significantly. Patients with isolated full-thickness supraspinatus tears had the best results, followed by those with partial tears, intact cuffs, or large tears involving more than 1 tendon. ASD in the treatment of subacromial impingement yields good long-term results. Small full-thickness supraspinatus tears had the best results, indicating that the ASD might prevent further cuff deterioration and that repair of these lesions may be unnecessary. © 2008 Journal of Shoulder and Elbow Surgery Board of Trustees.
