End stage glenohumeral joint arthritis is common in patients with inflammatory arthritis. Reverse shoulder arthroplasty (RSA) and anatomic total shoulder arthroplasty (TSA) are both indicated in this setting. RSA is often considered based upon the impacts of longstanding inflammatory arthritis including glenoid and humeral bone erosion and rotator cuff insufficiency. However, acromion and scapular spine fractures following RSA have been reported more commonly in these patients, which can have significant impact on outcome. Currently, no study has directly compared the efficacy and complication rates of RSA to TSA in patients with inflammatory arthritis. This study aims to investigate differences in clinical outcomes and complications amongst patients undergoing RSA and TSA with glenohumeral inflammatory arthritis.
