Popis: Background This study evaluated the clinical and radiologic mid-term outcomes of anatomic total shoulder arthroplasty for osteoarthritis using a new stemless system. Methods Between July 2015 and May 2018, 49 shoulders in 47 patients received an anatomic total shoulder arthroplasty for osteoarthritis with the SMR Stemless shoulder system. Forty patients could be included. A review was conducted at a minimum follow-up of 24 months. There were 18 male and 22 female patients. The average age at the time of surgery was 67 years. Clinical evaluation was conducted using the Oxford Shoulder Score (OSS), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), scoring patient satisfaction, and range of motion. Standardized radiographs were assessed for radiolucency, loosening, superior migration of the humeral head, and reduced bone density. Results The mean clinical follow-up was 35 months (range, 24-54 months). The mean OSS was 46 points (range, 35-48) and the mean ASES score was 89 points (range, 52-100) at final follow-up. The rate of either “satisfied” or “very satisfied” patients was 97%. No radiolucency around the humeral implant or loosening was found. Radiolucent lines of 2 mm or less around the glenoid were detected in 3 shoulders. The overall complication rate was 7.5% and the rate of revision was 5%. Conclusions Patients treated with the SMR Stemless Shoulder System for shoulder osteoarthritis achieved good clinical and radiologic results comparable with the midterm results of other stemless designs. The convertible design of the SMR Stemless simplifies future revision to reverse total shoulder arthroplasty. Level of evidence Level IV; Case Series; Treatment Study.
