“…These arthroplasties were performed as part of a US Food and Drug Administration Investigational Device Exemption study in North America and a European post-market clinical follow-up study. 10 The inclusion criteria for the patients enrolled in this study were age of 18 years or older, skeletal maturity, patients with primary osteoarthritis in whom conservative treatment failed and shoulder arthroplasty was indicated, willingness to participate in the study follow-up period, and ability to provide informed consent. The exclusion criteria included the following: patients who were considered vulnerable adults (prisoners, current abusers of illicit drugs or alcohol, or patients with active psychiatric illness preventing the ability to provide informed consent), unwillingness to participate in the study followup, inability to comply with the postoperative protocol, pregnancy, Charcot arthropathy, irreparable rotator cuff tear, evidence of infection, post-traumatic etiology, metaphyseal osseous defect, and soft or inadequate humeral bone.…”

Background: It is unknown whether subscapularis management technique has an influence on the outcomes and complications of stemless total shoulder arthroplasty. The purpose of this study, therefore, was to compare outcomes and complications between subscapularis tenotomy, peel, and lesser tuberosity osteotomy used during stemless shoulder arthroplasty. Methods: We reviewed 188 stemless anatomic total shoulder arthroplasties and compared clinical and functional outcomes between those performed through a subscapularis tenotomy (n ¼ 68), subscapularis peel (n ¼ 65), or lesser tuberosity osteotomy (n ¼ 55). Patients were followed up clinically and radiographically at 6 months, 1 year, and 2 years postoperatively. Results: At 2 years postoperatively, no statistically significant differences in visual analog scale pain scores, American Shoulder and Elbow Surgeons scores, or patient-reported instability (P .19) were found between groups. Active external rotation was greater in the peel group (P ¼ .006) than in the tenotomy group but was not different compared with the lesser tuberosity osteotomy group (P ¼ .07). No statistically significant difference in clinical subscapularis failures was noted between groups (P ¼ .11); however, 2 patients in the peel group sustained a subscapularis failure requiring reoperation. Discussion: The results of this multicenter comparative analysis show that all 3 subscapularis management techniques are effective and safe in the short term when used with stemless anatomic total shoulder arthroplasty.

BackgroundThe number of anatomic total shoulder (TSA), hemiarthroplasty (HA), and reverse total shoulder arthroplasties (RTSA) is rapidly increasing in the United States. Stemless shoulder arthroplasty has numerous theoretical advantages, including preserved bone stock, decreased operating time, reduced rate of intraoperative humerus fracture, and flexibility of anatomic reconstruction. Only recently studies with more than 5 years of mean follow-up have become available.MethodsThe MEDLINE database was systematically queried to identify all studies reporting outcomes regarding anatomic or reverse stemless shoulder arthroplasty. Studies were categorized according to mean reported follow-up. Outcome scores and range of motion measurements were compiled. Complication and revision rates due to failure of the humeral or glenoid components were summarized.ResultsNineteen TSA and HA studies with a total of 1115 patients were identified, with 4 studies and 162 patients with a mean follow-up between 60 and 120 months. Six RTSA studies with a total of 346 patients were identified, all with a mean follow-up between 18 and 60 months. There was a reliable improvement in outcomes compared with preoperative scores across studies. A cumulative 0.7% (8 of 1115) humeral component complication rate was found for TSA and HA components. There was a cumulative 1.7% (6 of 346) humeral complication rate for RTSA prostheses.ConclusionsIn the studies reporting similar outcome measures, there were reliable improvements on par with stemmed counterparts. Aggregate complication rates appear similar to those published in the literature for stemmed components. Evidence supporting the utility and safety of stemless designs would be strengthened by longer-term follow-up and additional prospective comparative studies.

Introduction: Anatomic total shoulder arthroplasty is the replacement of the humeral head and glenoid surfaces with the goal of replicating normal anatomy. It is commonly utilized for patients with osteoarthritis, rheumatoid arthritis, and osteonecrosis, who have decreased range of motion (ROM), persistent pain, and loss of strength. Total shoulder Arthroplasty (TSA) is the third most common joint replacement in the United States. The incidence of TSA has been increasing, some data suggest that by the year 2025, TSA incidence may rise to 439,206 operations per year. In recent years, stemless total shoulder implants have become available. Results: These implants preserve bone stock while decreasing complications such as osteolysis, stress shielding and periprosthetic fracture. Stemless implants improve anatomic reconstruction and biomechanical function of the shoulder joint. Conclusion: Increasing amounts of data suggest stemless TSA to be a safe and effective technology that will become more common in the coming year.
