title: Shoulder hemiarthroplasty for acute fractures of the proximal humerus: a minimum five-year follow-up.
abstract: Significant discrepancy in the functional outcome of hemiarthroplasty for proximal humerus fractures has been reported with short or mid-term follow-up. This study reports the long-term results and rate of complications of shoulder arthroplasty in the treatment of proximal humerus fractures. The review comprised 57 patients (44 women, 13 men) who underwent hemiarthroplasty between 1976 and 1996 as treatment of a proximal humerus fracture and who had a minimum 5-year follow-up (mean, 10.3 years). The mean patient age was 66 years at the time of surgery (range, 23-89 years). According to a modified Neer result rating system, results were satisfactory in 27 patients and unsatisfactory in 30. The mean active elevation was 100 degrees (range, 20 degrees -180 degrees ) and external rotation was 30 degrees (range, 0 degrees -90 degrees ). At the most recent follow-up, 9 patients (16%) had moderate or severe pain and 2 required implant revision or removal. The study data suggest that patients undergoing arthroplasty as treatment of an acute fracture of the proximal humerus may achieve satisfactory long-term pain relief; however, the result for overall shoulder motion is less predictable. In view of these results, current indications, surgical technique, and postoperative treatment may need to be revisited.
