Introduction: While uncommon, humeral head osteonecrosis is an indication for arthroplasty when the humeral head collapse is advanced. The current authors report the short-term clinical results of 7 hemiarthroplasties to treat humeral head osteonecrosis.
Materials and Methods: This study focused on 7 reconstructed shoulders of 5 patients whose humeral head osteonecrosis was treated with hemiarthroplasty. The postulated causes were alcohol-induced (4 cases) and steroidinduced (3 cases). The minimum follow-up was 12 months. This study compared the preoperative and postoperative shoulder pain, range of motion, and ASES scores. The postoperative patient satisfaction was assessed.
Results: The level of pain during exercise was reduced from a preoperative average of 7.6 to a postoperative average of 1.9. The range of motion, in terms of forward flexion, abduction, and external rotation, improved from preoperative averages of 105.7˚, 80˚, and 22.1˚to postoperative averages of 146.6˚, 139.3˚, and 44.3˚, respectively. The ASES scores increased from a preoperative mean of 39.0 to a postoperative mean of 84.1. The patients’ ratings of the outcomes were excellent (5 cases) and good (2 cases).
Conclusions: These short-term results indicate that hemiarthroplasty is a reliable treatment method for humeral head osteonecrosis improving shoulder pain, range of motion, and patient satisfaction.
