Clinical and radiologic outcomes following total shoulder arthroplasty using Arthrex Eclipse stemless humeral component with minimum 2 years' follow-up

Stemless humeral components benefit from less morbidity, better reproduction of the humeral anatomy, ease of revision, and fewer stem-related complications. Encouraging results are available up to 9 years after surgery from the designer's series. This is an independent study of 100 consecutive Eclipse stemless prostheses for osteoarthritis with a minimum 2-year follow-up (range, 2-6 years). We included only total shoulder arthroplasties performed for osteoarthritis. The primary outcome was the Oxford Shoulder Score (OSS) after 2 years. Secondary outcome measures were change in shoulder range of movement and radiographic analysis of prosthesis size and position. The mean OSS at 2 years was 38 of 48, with a mean improvement of +19 points (range, +17 to +22 points; P
