This retrospective cohort study tracks 27 patients (28 shoulders) who underwent shoulder hemiarthroplasty for glenohumeral osteoarthritis at a single institution, reporting outcomes at an average of 17.2 years — one of the longest follow-up series available. It asks whether long-term satisfaction, revision rates, and functional outcomes differ based on glenoid wear pattern (concentric vs. eccentric) and osteoarthritis etiology (primary vs. secondary).
