Midterm results of shoulder hemiarthroplasty for glenohumeral osteoarthritis

Abstract

BackgroundDegenerative disease is a common cause of shoulder pain and dysfunction. Osteoarthritis is the most frequent cause of the degeneration. Prosthetic shoulder arthroplasty is becoming increasingly popular. The most widely reported procedure is hemiarthroplasty.Patients and methodsThirty patients were included in this study. The average age of the patients was 55 years. The deltopectoral approach was adopted in all cases, and the prosthesis implanted in all patients was the global prosthesis. The mean follow-up period was 36 months. The Simple Shoulder Test (SST) was used for functional evaluation of patients. The initial SST questionnaire was administered before surgery, and the final SST questionnaire was administered at the most recent follow-up.ResultsAt the most recent follow-up, the average active elevation was 90°. The mean SST score at final follow-up was 9.5 of 12. There were no reports of prosthesis loosening or prosthesis subsidence.ConclusionThe data from this study suggest that hemiarthroplasty is a reliable procedure with good results for improvement in pain, range of motion, and function. Prosthetic arthroplasty remains the treatment of choice for the management of end-stage osteoarthritis.
