Long-term results of shoulder hemiarthroplasty in patients with rheumatoid arthritis.

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.
