    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.

    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.

    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.

    The influence of cuff pathology on shoulder function after arthroscopic subacromial decompression: A 3- and 6-year follow-up study1999Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 8, nr 6, s. 585-589Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In the literature operative management of rotator cuff ruptures in the shoulder varies, from tendon repair to debridement of the cuff lesion combined with subacromial decompression. This study was made to evaluate whether patients with intact rotator cuff differed from patients with rotator cuff ruptures regarding functional outcome after arthroscopic subacromial decompression. We performed a clinical review of 39 patients with subacromial impingement who all underwent arthroscopic subacromial decompression; no other surgery was performed. There were 13 patients with intact cuff, 13 patients with partial-thickness supraspinatus ruptures, and 13 patients with full-thickness supraspinatus ruptures <2 cm. Selection was based solely on the status of the supraspinatus tendon. Patients with other pathologic conditions were excluded. Follow-up was performed after 3 and 6 years. The clinical evaluation was performed with the Constant score and the visual analog pain score. The 3- and 6-year follow-up (100% follow-up rate) revealed no significant difference between the groups regarding the Constant scores and the visual analog scale values. Also, no significant difference was seen among the 3 groups in active range of motion or strength, and the patients had no appreciable pain. We conclude that the functional outcome 6 years after arthroscopic subacromial decompression is not obviously related to the preoperative degree of cuff pathology, even if a total rupture of small size is present.

    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.

    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.

    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.

    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.

    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.

    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.

    Fatty infiltration and muscle atrophy of the rotator cuff in stemless total shoulder arthroplasty: a prospective cohort study2018Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 27, nr 6, s. 976-982Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The influence of preoperative rotator cuff fatty infiltration (FI) and muscle atrophy (MA) on the postoperative outcome of total shoulder arthroplasty (TSA) has only rarely been investigated and reported in the literature. We hypothesized that more FI and MA would be associated with a worse postoperative functional outcome. Methods: This prospective cohort study included 63 patients (31 female and 32 male patients; mean age, 71 years [range, 53-89 years; standard deviation, 7 years]) with primary osteoarthritis of the shoulder operated on with anatomic stemless TSA. Preoperatively and at 3 months and 1 year after the operation, the functional outcome (QuickDASH [short version of Disabilities of the Arm, Shoulder and Hand questionnaire] score) and range of motion (ROM) (goniometer) and strength (dynamometer) for abduction at the scapular plane and for external rotation were measured. The degree of preoperative FI and MA was evaluated using computed tomography scans according to the Goutallier classification and Warner classification, respectively, for the supraspinatus and infraspinatus. Results: We found clinically and statistically significant improvements in functional outcome, strength, and ROM at both 3 months and 1 year of follow-up compared with those preoperatively. The Pearson correlation coefficient (r) showed significant correlations between preoperative supraspinatus and infraspinatus FI and MA and preoperative and 1-year postoperative shoulder abduction and external rotation strength but not ROM. However, we found no influence of the rotator cuff FI and MA on the functional outcome after TSA. Conclusion: We demonstrated a significant correlation between rotator cuff FI and MA and strength but not ROM of the shoulder joint. (C) 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

    Topical benzoyl peroxide application on the shoulder reduces Propionibacterium acnes: a randomized study2018Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 27, nr 6, s. 957-961Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Propionibacterium acnes is a common cause of infection following shoulder surgery. Studies have shown that standard surgical preparation does not eradicate P acnes. The purpose of this study was to examine whether topical application of benzoyl peroxide (BPO) gel could decrease the presence of P acnes compared with todays standard treatment with chlorhexidine soap (CHS). We also investigated and compared the recolonization of the skin after surgical preparation and draping between the BPO- and CHS-treated groups. Methods: In this single-blinded nonsurgical study, 40 volunteers-24 men and 16 women-were randomized to preoperative topical treatment at home with either 5% BPO or 4% CHS on the left shoulder at the area of a deltopectoral approach. Four skin swabs from the area were taken in a standardized manner at different times: before and after topical treatment, after surgical skin preparation and sterile draping, and 120 minutes after draping. Results: Topical treatment with BPO significantly reduced the presence of P acnes measured as the number of colony-forming units on the skin after surgical preparation. P acnes was found in 1 of 20 subjects in the BPO group and 7 of 20 in the CHS group (P = .044). The results remained after 2 hours (P = .048). Conclusion: Topical preparation with BPO before shoulder surgery may be effective in reducing P acnes on the skin and preventing recolonization. Conclusion: Topical preparation with BPO before shoulder surgery may be effective in reducing P acnes on the skin and preventing recolonization.

    Intraoperative measurement of shoulder translation2001Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 10, nr 4, s. 358-364Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Assessing laxity of the shoulder joint in patients who are under anesthesia is a standard procedure before arthroscopy. The aim of this study was to evaluate a novel instrument for quick and reliable intraoperative measurement of glenohumeral translation. Previous testing of various designs has resulted in a device secured by 1 pin in the acromion and 1 pin in the proximal humerus. These pins are interconnected by a sliding ruler that gives translation values in millimeter increments as the laxity tests are performed. Comparison between manual arbitrary approximation of laxity and instrumented translation measurements showed that manual testing is reasonably good for assessment of anterior and posterior translation, without, however, providing values of translation in millimeter increments. The low correlation between manual assessment and instrumented inferior translation measurements indicates that inferior translation is more difficult to approximate manually. The shoulder translation tester was used in 102 patients. The mean values for clinically stable shoulders (n = 58) were 5 mm for anterior translation, 5 mm for posterior translation, and 4 mm for inferior translation. The corresponding values in unstable shoulders were significantly higher than in the stable shoulders, especially in patients with multidirectional instability. We conclude that the shoulder translation tester is easy and quick to use. It provides quantitative values of translation and will thus contribute information for correct diagnosis, therapy, and documentation.

    Complications and survival after surgical treatment of 214 metastatic lesions of the humerus2012Ingår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 21, nr 8, s. 1049-1055Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus. MATERIALS AND METHODS: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus. Reconstructions were achieved by intramedullary nails in 148, endoprostheses in 35, plate fixation in 21, and by other methods in 10. RESULTS: The median age at surgery was 67 years (range, 29-87 years). Breast cancer was the primary tumor in 31%. The overall failure rate of the surgical reconstructions was 9%. The reoperation rate was 7% in the proximal humerus, 8% in the diaphysis, and 33% in the distal part of the bone. Among 36 operations involving an endoprosthesis, 2 were failures (6%) compared with 18 of 178 osteosynthetic devices (10%). In the osteosynthesis group, intramedullary nails failed in 7% and plate fixation failed in 22%. Multivariate Cox regression analysis showed that prostate cancer was associated with an increased risk of failure after surgery (hazard ratio, 7; P < 0.033). The cumulative survival after surgery was 40% (95% confidence interval [CI] 34-47) at 1 year, 21% (95% CI, 15-26) at 2 years, and 16% (95% CI, 12-19) at 3 years. CONCLUSIONS: Our method of choice is the cemented hemiprosthesis for pathologic proximal humeral fractures and interlocked intramedullary nail for lesions in the diaphysis. Pathologic fractures in the distal humerus are uncommon and associated with a very high reoperation rate.
