Abstract Rheumatoid arthritis affecting the shoulder is typically associated with destruction of the glenohumeral joint and rotator cuff impairment, which can result in severe glenoid erosion. Following hemiarthroplasty, severe glenoid erosion has also frequently been observed. The authors' aim was to retrospectively evaluate the outcome of cemented shoulder hemiarthroplasty in patients with rheumatoid arthritis. The authors performed 45 cemented hemiarthroplasties in 36 patients with rheumatoid arthritis involving the shoulder as well as associated rotator cuff compromise between 1995 and 2008. All patients were analyzed radiologically and clinically using patient-reported outcome measures. Mean±SD visual analog pain scale score was 3±2. Mean±SD Constant score was 55±16. Mean±SD validated Dutch version of the Disabilities of the Arm Shoulder and Hand (DASH) score was 42±19. No radiograph showed loosening of the implant at follow-up. One patient needed an arthrotomy and capsulotomy because of persistent pain and limited range of motion. Tissue cultures taken during this second operation were negative for infection. No major revision surgery was necessary within the follow-up period. Cemented hemiarthroplasty is a viable treatment option for glenohumeral arthritis in patients with rheumatoid arthritis. Long-term results show acceptable results and low complication rates in this case series for this specific group. A randomized, controlled trial comparing hemiarthroplasty, total shoulder arthroplasty, and reverse shoulder arthroplasty is necessary to draw definite conclusions in this specific patient population.
