    Arthroscopic removal of os centrale carpi causing wrist pain.2000In: Arthroscopy: The Journal of Arthroscopy And Related, ISSN 0749-8063, E-ISSN 1526-3231, Vol. 16, 537-539 p.Article in journal (Refereed)
    Abstract [en]

    The Os centrale carpi is a relatively rare accessory carpal bone of the wrist that infrequently has been reported to cause symptoms. This report describes 2 cases where an apparently mobile Os centrale carpi caused painful clicking and crepitus and where the symptoms disappeared after arthroscopic removal of the ossicles.

    Arthroscopic synovectomy in wrist arthritis2005In: Hand Clinics, ISSN 0749-0712, E-ISSN 1558-1969, Vol. 21, no 4, 527-530 p.Article, review/survey (Refereed)
    Abstract [en]

    Arthroscopic synovectomy is a safe outpatient procedure with minimal postoperative morbidity. In patients who have rheumatoid arthritis and possibly also in patients who have JRA, SLE, and postinfectious arthritis, a long period of increased comfort and improved function can be anticipated. The procedure may be considered in post-traumatic cases with joint contracture and as an adjunct to other measures for certain osteoarthritic disorders. In patients who have septic arthritis with insufficient clinical improvement after systemic antibiotics and lavage, arthroscopic synovectomy seems advantageous. © 2005 Elsevier Inc.

    Arthroscopic Synovectomy of the Wrist2011In: Hand Clinics, ISSN 0749-0712, E-ISSN 1558-1969, Vol. 27, no 3, 395-399 p.Article in journal (Refereed)
    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.

    Arthroscopy in the upper extremity1992Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This stndy comprising six separate papers, is concerned with the techniques of, and bevaluation of arthroscopy as a diagnostic and therapeutic tool in different pathologic conditions in the upper extremity.

    Arthroscopy proved to increase diagnostic accuracy in 177 examined patients with anterior shoulder instability or shoulder pain. Previously not well described patterns of pathological morphology in the ventral joint capsule after anterior shoulder dislocations were disclosed. A new classification system of rotator cuff pathology to be used for arthroscopy in the subacromial impingement syndrome is suggested. Different stages of rotator cuff pathology were found to influence the clinical results after arthroscopic acromioplasty in 79 patients.

    An anatomical stndy on 16 cadaver elbows revealed the close proximity between commonly used arthroscopic portals and important neurovascular structures. The usefulness and potential risks of each portal were demonstrated and a preferred procedure for diagnostic elbow arthroscopy was suggested.

    Wrist arthroscopy was performed in 30 patients with long-standing post-traumatic pain and resulted in increased diagnostic accuracy. In patients where clinical examination and radiography had shown no abnormality, arthroscopy demonstrated serious carpal ligament injuries and related instability.

    A technique for arthroscopic wrist synovectomy was described in patients with rheumatoid arthritis. In 18 wrists of 16 patients, a reasonably radical synovectomy could be achieved with this atraumatic method. Primary results showed decreased pain and increased grip-strength in all patients and an increased range of motion in some.

    Open vs. arthroscopic synovectomy of the wrist2006In: Excerpta Medica: International Congress Series, ISSN 0531-5131, E-ISSN 1873-6157, Vol. 1295, 56-62 p.Article in journal (Refereed)
    Abstract [en]

    Synovectomy may be considered for the treatment of chronic wrist arthritis. The indications for wrist synovectomy are, however, not clearly defined. Open synovectomy has been reported to provide good pain relief for a relatively long time but can be associated with loss of mobility. Arthroscopic synovectomy seems equally reliable in terms of symptom reduction and no adverse effects have been reported. © 2006 Elsevier B.V. All rights reserved.

    Elbow hemiarthroplasty for acute reconstruction of intraarticular distal humerus fractures: A preliminary report involving 4 patients2006In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 77, no 5, 785-787 p.Article in journal (Refereed)
    Abstract [en]

    We treated 4 female patients (mean age 80) with complex intraarticular acute fracture of the distal humerus with a Kudo humeral component, i.e. a hemiarthroplasty. All fractures were considered impossible to treat with open reduction and internal fixation. At mean 10 (3-14) months, 3 patients had an excellent result and 1 a good result according to the Mayo elbow performance score. We conclude that a hemiarthroplasty may be a valuable alternative in eldery patients with complex fractures of the distal humerus. Copyright© Taylor & Francis 2006.

    The Kudo humeral component as primary hemiarthroplasty in distal humeral fractures2012In: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 21, no 4, 451-455 p.Article in journal (Refereed)
    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 findings in wrists with severe post-traumatic pain despite normal standard radiographs2004In: Journal of Hand Surgery - British and European Volume, ISSN 0266-7681, E-ISSN 1532-2211, Vol. 29 B, no 3, 208-213 p.Article in journal (Refereed)
    Abstract [en]

    This study assessed the role of diagnostic arthroscopy following a wrist injury in patients with normal standard radiographs, an unclear clinical diagnosis and persistent severe pain at 4 to 12 weeks. Forty-three patients were included after conservative management had failed to improve their wrist pain so that a stability test could be performed satisfactorily and underwent arthroscopy within 12 weeks. Arthroscopy revealed recent pathology in 41 wrists, of which 17 had significant ligament lesions that might have benefited from acute repair. We conclude that patients with marked persistent post-traumatic symptoms despite conservative management are likely to have sustained ligament injuries despite normal radiographs. We therefore recommend that under these circumstances an arthroscopy is carried out within 4 weeks if the patient and surgeon wish to acutely repair significant ligament injuries.

    Elevated plasma levels of TIMP-1 in patients with rotator cuff tear2012In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 83, no 5, 523-528 p.Article in journal (Refereed)
    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.

    A specific exercise strategy for patients with subacromial pain significantly reduced the need for surgery: one-year results of a randomised controlled studyManuscript (preprint) (Other academic)
    Abstract [en]

    Background: A specific exercise strategy focusing on eccentric exercises, for treating sbacromial pain has in a previous study been found effective at three-month followup.

    The aim of the present study was to investigate if the positive short-term results were maintained after one year. A further aim was to examine if baseline clinical score, rotator cuff status and radiological findings influenced the choice of surgery.

    Methods: 97 patients on the waiting-list for arthroscopic subacromial decompression were in the first study randomized to a three-month specific exercise strategy or unspecific exercises (controls). Patients were examined with radiology, ultrasound and assessed with clinical scores: primary Constant-Murley score. After three months of exercises the patients were asked if they still wanted surgery and this option was available until the one-year follow-up. All patients were re-assessed with clinical scores one year after inclusion or one year after surgical intervention and the number of patients that had chosen surgery in each group was compared. The baseline Constant-Murley score and the status of subacromial structures were analyzed in relation to patient's choice of surgery.

    Results: The positive short-term effect (improved shoulder function and pain) of the specific exercises was maintained after one-year. Compared to the three-month followup all patients had improved significantly (p < 0.0001) in Constant-Murley score. The number of patients that had chosen surgery in the control exercise group (63%) was significantly larger (p < 0.0001) than in the specific exercise group (24%). Patients that had chosen surgery had a significantly lower baseline Constant-Murley score and significantly more often a full-thickness tear. Patients with partial-thickness tears did not differ from those with intact cuff tendons.

    Conclusions: The positive short-term outcomes after specific exercises were maintained after one year and reduced the need of surgery significantly more than the unspecific control exercises. Patients with low baseline clinical score and/or a full-thickness tear significantly more often chose surgery.

    Level of evidence: I, Randomized controlled trail according to Consort statement.

    A specific exercise strategy reduced the need for surgery in subacromial pain patients2014In: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 48, no 19, 1431-1436 p.Article in journal (Refereed)
    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.

    The influence of age, delay of repair, and tendon involvement in acute rotator cuff tears Structural and clinical outcomes after repair of 42 shoulders2011In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 82, no 2, 187-192 p.Article in journal (Refereed)
    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 decompression2010In: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 19, no 1, 111-115 p.Article in journal (Refereed)
    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.

    Different effect on axonal outgrowth of application of non-absorbable or absorbable tubes around a nerve repair2001In: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery, ISSN 2000-656X, E-ISSN 2000-6764, Vol. 35, no 4, 347-353 p.Article in journal (Refereed)
    Abstract [en]

    We studied regeneration distance of rat sciatic nerve, with the sensory pinch reflex test and immunocytochemical staining for neurofilaments, four to 21 days after transsection, repair, and enclosure of the repair site in either a non-absorbable silicone tube or an absorbable polyglycolic acid (PGA) tube. The size of both tube-types was carefully selected so that they did not compress the repaired nerve. The opposite nerve was repaired and not inserted in a tube (control). The regeneration distances in repaired nerves enclosed in silicone tube were significantly longer than the control side at all time points, a result not seen when PGA tube was used. The number of proliferating non-neuronal cells (incorporation of 5-bromodeoxyuridine (BrdU)) was studied just proximal to the site of nerve repair after six days. Numerous stained cells were seen, but there where no significant differences between the groups. We conclude that outgrowth of sensory axons after transsection and repair of rat sciatic nerve with sutures can be increased by enclosing the site of repair in a silicone tube but not in a PGA tube. The effect is probably not related to the number of proliferative non-neuronal cells.

    Effect of specific exercise strategy on need for surgery in patients with subacromial impingement syndrome: randomised controlled study2012In: BMJ. British Medical Journal (International Ed.), ISSN 0959-8146, E-ISSN 0959-535X, Vol. 344, e787- p.Article in journal (Refereed)
    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.

    TRIAL REGISTRATION: Clinical trials NCT01037673.

    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.

    Minimal important changes in the Constant Murley score in patients with subacromial pain2014In: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 23, no 8, 1083-1090 p.Article in journal (Refereed)
    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.

    Patterns of triangular fibrocartilage complex (TFCC) injury associated with severely dorsally displaced extra-articular distal radius fractures2012In: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 43, no 6, 926-932 p.Article in journal (Refereed)
    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.

    Radioulnar laxity and clinical outcome after a distal radius fracture do not correlate after a distal radius fracture2011In: Journal of Hand Surgery - British and European Volume, ISSN 0266-7681, E-ISSN 1532-2211, Vol. 36, no 6, 503-508 p.Article in journal (Refereed)
    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.

    Intraobserver and interobserver reliability for the strength test in the Constant-Murley shoulder assessment2005In: Journal of Shoulder and Elbow Surgery, ISSN 1058-2746, Vol. 14, no 3, 273-278 p.Article in journal (Refereed)
    Abstract [en]

    This study evaluates the standardized strength test in the Constant-Murley shoulder assessment of adults with healthy shoulders in a randomized, single-blind design. The following questions were to be answered: (1) Can the spring balance and a digital dynamometer both yield the same result? (2) What is the intraobserver and interobserver reliability of the strength test? (3) Is the strength test sensitive to change in technique or affected by calculation with mean or maximum values? Ten subjects were included in a comparison of the Handyscale (digital dynamometer) and the mechanical spring balance for concurrent validity, resulting in intraclass correlation coefficient values ranging from 0.96 to 0.99. For intraobserver and interobserver reliability, 2 observers tested 20 subjects with the Handyscale and retested them after 2 weeks. Regardless of technique during testing, this resulted in almost perfect agreement (intraclass correlation coefficient range, 0.89–0.98). The digital dynamometer can replace the conventional spring balance. The standardized strength test in the Constant-Murley shoulder assessment is reliable in young subjects with healthy shoulders, independent of technique or whether calculated with mean or maximum values.

    Attitudes toward management of patients with subacromial pain in Swedish primary care1999In: Family Practice, ISSN 0263-2136, Vol. 16, no 3, 233-237 p.Article in journal (Refereed)
    Abstract [en]

    Objective. We aimed to describe the attitudes among GPs and physiotherapists toward the diagnostic approach and management of patients with a common shoulder disorder.

    Method. A questionnaire was sent out to 188 GPs and 71 physiotherapists. The total response rate was 71.8%. The questions were based on a written case simulation with cues about history and symptoms.

    Results. The results showed a unanimous opinion of the diagnosis. Rotator cuff tendinitis was marked as the most probable. The two groups showed similarities in the way that they would examine the patient. The GPs referred the patients to the physiotherapists significantly more often than the other way around. The most probable choice of treatment made by the GPs was non-steroidal anti-inflammatory drugs (NSAIDs) and by the physiotherapists, movement exercises together with ergonomics. Most treatment alternatives had at least 20% of the responders marking a neutral attitude, and few treatments were disregarded.

    Conclusions. We conclude that in Swedish primary care GPs and physiotherapists have a uniform diagnostic approach towards patients with subacromial pain, but their choice of treatment reflects an uncertainty about the effectiveness of conservative treatments. The questioned pathogenesis of the suggested diagnosis and lack of research regarding the efficacy of conservative treatments could explain this uncertainty.

    Effects of acupuncture versus ultrasound for patients with impingement syndrome: Randomized clinical trial2005In: Physical Therapy, ISSN 0031-9023, E-ISSN 1538-6724, Vol. 85, no 6, 490-501 p.Article in journal (Refereed)
    Abstract [en]

    Background and Purpose. There is no definitive evidence for the efficacy of the physical therapy interventions used for patients with impingement syndrome. The purpose of this study was to compare manual acupuncture and continuous ultrasound, both applied in addition to home exercises, for patients diagnosed with impingement syndrome.

    Subjects and Methods. Eighty-five patients with clinical signs of impingement syndrome were randomly assigned to either a group that received acupuncture (n=44) or a group that received ultrasound (n=41). Both interventions were given by physical therapists twice a week for 5 weeks in addition to a home exercise program. Scores from 3 shoulder disability measures, combined in the analysis, measured change during a period of 12 months.

    Results. Both groups improved, but the acupuncture group had a larger improvement in the combined score.

    Discussion and Conclusion. The results suggest that acupuncture is more efficacious than ultrasound when applied in addition to home exercises.

    A combination of systematic review and clinicians’ beliefs in interventions for subacromial pain2002In: British Journal of General Practice, ISSN 0960-1643, Vol. 52, no 475, 145-152 p.Article in journal (Refereed)
    Abstract [en]

    The aim of the study is to determine which treatments for patients with subacromial pain are trusted by general practitioners (GPs) and physiotherapists, and to compare trusted treatments with evidence from a systematic critical review of the scientific literature. A two-step process was used: a questionnaire (written case simulation) and a systematic critical review. The questionnaire was mailed to 18 GPs and 71 physiotherapists in Sweden. The total response rate was 72% (186/259). The following treatments were trusted: ergonomics/adjustments at work, corticosteroids, non-steroidal anti-inflamatory drugs, movement exercises, acupuncture, ultrasound therapy, strengthening exercises, stretching, transcutaneous electric nerve stimulation, and superficial heat or ice therapy. The review, including efficacy studies for the treatments found to be trusted, was conducted using the CINAHL, EMBASE and MEDLINE databases. Evidence for efficacy was recorded in relation to methodological quality and to diagnostic criteria that labelled participants as having subacromial pain or a non-specific shoulder disorder. Forty studies were included. The methodological quality varied and only one treatment had definitive evidence for efficacy for non-specific patients, namely injection of corticosteroids. The trust in corticosteroids, injected in the subacromial bursa, was supported by definitive evidence for short-term efficacy. Acupuncture had tentative evidence for short-term efficacy in patients with subacromial pain. Ultrasound therapy was ineffective for subacromial pain. This is supported by tentative evidence and, together with earlier reviews, this questions both the trust in the treatment and its use. The clinicians' trust in treatments had a weak association with available scientific evidence.

    Hemiarthroplasty for irreparable distal humeral fractures: Medium-term follow-up of 42 patients2015In: The Bone & Joint Journal, ISSN 2049-4394, E-ISSN 2049-4408, Vol. 97B, no 10, 1377-1384 p.Article in journal (Refereed)
    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.

    Small full-thickness tears do well ten to thirteen years after arthroscopic subacromial decompression2008In: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 17, no 1 SUPPL.Article in journal (Refereed)
    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.

    Non-union in 3 of 15 osteotomies of the distal radius without bone graft2015In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 86, no 3, 316-320 p.Article in journal (Refereed)
    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.

    Pathomechanisms of ulnar ligament lesions of the wrist in a cadaveric distal radius fracture model2011In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 82, no 3, 360-364 p.Article in journal (Refereed)
    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.

    Tricalcium phosphate bone substitute in corrective osteotomy of the distal radius2009In: INJURY-INTERNATIONAL JOURNAL OF THE CARE OF THE INJURED, ISSN 0020-1383, Vol. 40, no 3, 262-267 p.Article in journal (Refereed)
    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.

    Radioulnar ratio in detection of distal radioulnar joint instability associated with acute distal radius fractures2010In: JOURNAL OF HAND SURGERY (EUROPEAN VOLUME), ISSN 1753-1934, Vol. 35E, no 9, 730-734 p.Article in journal (Refereed)
    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.

    Transclavicular Osseous Sutures for the Treatment of Displaced Distal Clavicular Fractures in Children2016In: Journal of Orthopaedic Trauma, ISSN 0890-5339, E-ISSN 1531-2291, Vol. 30, no 5, E181-E185 p.Article in journal (Refereed)
    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.

    Conservative treatment of the cubital tunnel syndrome2009In: Journal of Hand Surgery: European Volume, ISSN 1753-1934, Vol. 34, no 2, 201-207 p.Article in journal (Refereed)
    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.

    Non-operative treatment regime including eccentric training for lateral humeral epicondylalgia2001In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 11, no 6, 328-334 p.Article in journal (Refereed)
    Abstract [en]

    In a pilot study 38 patients with lateral humeral epicondylalgia were randomly allocated to two treatment groups. Group S (stretching) was treated with a contract-relax-stretching program while group E (eccentric exercise) underwent an eccentric exercise program. Both groups also received forearm bands and wrist support nightly. The programs were carried out daily at home during 12 weeks. Evaluation before and 3, 6 and 12 months after treatment, included subjective assessment of symptoms using visual analogue scales and grip strength measurements. Thirty-five patients were available for follow-up. Five patients, three in group S and two in group E, did not complete the programs due to increased pain while 30 (86%) reported complete recovery or improvement. Reduced pain and increased grip strength were seen in both treatment groups but 12 out of 17 patients (71%) in group E rated themselves as completely recovered as compared to 7 out of 18 (39%) in group S (P=0.09), and in group E the increase in grip strength after 6 months was statistically significantly larger than in group S. In a second study the eccentric training regime was used in a consecutive series of 129 patients with lateral epicondy lalgia. The patients were divided into two groups with one group consisting of patients with less than one year duration of symtoms and the other comprised patients with a duration of symptoms for more than one year. The results of treatment were evaluated in the same way as in the pilot study, and also after 3.4 years using the scoring system by Verhaar et al. At the end of the treatment period statistically significant improvements were seen in all VAS recordings and in grip strength. After 3.4 years 38% had excellent, 28% good, 25% fair and 9% poor results according to the score. In the self-rated outcome 54% regarded themselves as completely recovered, 43% improved, 2% unchanged and 2% worse. No significant differences were seen between patients with a duration of symptoms for more than one year compared to patients with symptoms for less than one year. The eccentric training regime can considerably reduce symptoms in a majority of patients with lateral humeral epicondylalgia, regardless of duration, and is possibly superior to conventional stretching.

    Outcome of release of the lateral extensor muscle origin for epicondylitis2006In: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery, ISSN 2000-656X, E-ISSN 2000-6764, Vol. 40, no 3, 161-165 p.Article in journal (Refereed)
    Abstract [en]

    Fifty-five elbows in 53 patients affected by lateral epicondylitis for more than a year were operated on with lateral extensor release. Fifty-one patients (53 elbows) were followed-up 90 months postoperatively by two independent observers using Verhaar's score and the subjective grading scheme described by Svernlöv and Adolfsson. According to Verhaar's score 26 (49%) were excellent or good and 27 (51%) fair or poor. Women had significantly worse results than men (p

    Medial epicondylalgia (golfer’s elbow) treated by eccentric exercise2012In: Shoulder & Elbow, ISSN 1758-5732, Vol. 4, no 1, 50-55 p.Article in journal (Refereed)
    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.

    Patient-reported outcome of surgical treatment of nerve entrapments in the proximal forearm2011In: Advances in orthopedics, ISSN 2090-3472, Vol. 2011, 727689- p.Article in journal (Refereed)
    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.
