Sidus Stem-Free Shoulder System for primary osteoarthritis: short-term results of a multicenter study

BACKGROUND: The aim of this prospective multicenter study was to evaluate clinical and radiologic results of a new metaphyseal anchored system. This system features a different anchor geometry that potentially leads to better bony integration and less loosening. METHODS: From November 2012 until December 2015, 148 patients (151 shoulders) were treated with the Sidus Stem-Free Shoulder System at 9 centers in Europe. The main indication was primary osteoarthritis (80.1%). This analysis only includes patients diagnosed with primary osteoarthritis (n = 121). A clinical evaluation was performed using the Constant-Murley score, Subjective Shoulder Value, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, and range of motion. Radiologic assessment was based on the occurrence of radiolucent lines and signs of implant migration, osteolysis, loosening, and heterotopic ossification. RESULTS: We evaluated 105 patients after a follow-up period of 2 years. There were 53 women and 52 men. The average age was 64 years. Total shoulder arthroplasty was performed in 73 cases and hemiarthroplasty in 32. The Constant-Murley score improved from 26 points preoperatively to 70 points at 2 years' follow-up (P < .001). The Subjective Shoulder Value increased from 34% to 84% (P < .001), and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form increased from 34 points to 86 points (P < .001). Radiologically, neither migration nor loosening was found. However, radiolucent lines of 2 mm or greater could be detected around the glenoid in 2 cases, but none of them have had clinical relevance yet. The overall complication rate was 6.7%, and the revision rate was 0%. CONCLUSION: Patients with the Sidus Stem-Free Shoulder System achieve good clinical and radiologic short-term results that are comparable with the results of other stem-free shoulder implants

Golf participation after rotator cuff repair: functional outcomes, rate of return and factors associated with return to play

Background Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. Methods Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. Results Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). Conclusions Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf. Level of evidence Level IV

Management of degenerative rotator cuff tears: a review and treatment strategy

Abstract The aim of this review was to present an over view of degenerative rotator cuff tears and a suggested management protocol based upon current evidence. Degenerative rotator cuff tears are common and are a major cause of pain and shoulder dysfunction. The management of these tears is controversial, as to whether they should be managed non-operatively or operatively. In addition when operative intervention is undertaken, there is question as to what technique of repair should be used. This review describes the epidemiology and natural history of degenerative rotator cuff tears. The management options, and the evidence to support these, are reviewed. We also present our preferred management protocol and method, if applicable, for surgical fixation of degenerative rotator cuff tears.</p

Vascular Compromise Secondary to Acromioclavicular Joint Injury:A Case Report

Acromioclavicular dislocation is a common injury in young males. We present an unusual complication of vascular compromise occurring in a 27-year-old male manual labourer with a grade V acromioclavicular joint dislocation. Following modified Weaver–Dunn reconstruction, the patient had a good outcome, with total relief of symptoms, and returned to his previous occupation.</p

Short-Term Outcome after Arthroscopic Bursectomy Debridement of Rotator Cuff Calcific Tendonopathy with and Without Subacromial Decompression:A Prospective Randomized Controlled Trial

Purpose To conduct a prospective randomized controlled trial to assess whether arthroscopic bursectomy and debridement of the calcific deposit, with or without subacromial decompression, influences the functional outcome of patients with calcific tendonitis. Methods During a 4-year period, 80 patients were recruited who presented to the study center with refractory calcific tendonitis of the shoulder. Forty patients were randomized to have a subacromial decompression, and 40 were randomized not to have a subacromial decompression in combination with bursectomy and arthroscopic removal of the calcific deposit. All surgery was performed by one surgeon who was blinded to the functional assessment of the patients. Patient demographics, body mass index (BMI), and length of symptoms were recorded at the time of randomization. Patients were asked to complete a pain visual analog score (VAS), short form (SF-12), disability arm shoulder and hand (DASH), and Constant score (CS) preoperatively and at 1 year postoperatively. Results There were 21 male and 59 female patients with a mean age of 49 (range, 32 to 75) years. The mean time of follow-up was 13 (range, 12 to 15) months. There were no significant differences in gender, age, BMI, length of symptoms, or preoperative outcome measures assessed between the groups. Overall, for both groups there was a significant improvement in the pain VAS (P &lt;.001), DASH (P &lt;.001), and CS (P &lt;.001) at 1 year compared with preoperative scores. There were no significant differences demonstrated between the groups for improvement in the pain VAS (P =.57), DASH (P =.93), SF-12 physical component score (P =.58), or CS (P =.27) at 1 year. Conclusions This study has demonstrated that the short-term functional outcome of patients with calcific tendonitis after arthroscopic bursectomy and debridement of the calcific deposit is not influenced if performed in combination with or without a subacromial decompression.
