Abstract:
PURPOSE: The purpose of the study was to evaluate the results and analyze various prognostic factors of hemiarthroplasty for proximal humeral fractures. MATERIALS AND METHODS: Thirty-one cases, who underwent hemiarthroplasties for proximal humeral fractures, were evaluated with ASES score at a mean follow-up of 45 months (1-8 years). Global Total Shoulder (Depuy.) (TS Gr) for 21 cases, and Global FX (Depuy.) (FX Gr) for 10 cases were used. Twentysix cases were acute fractures within one month after injury. There were two cases with delayed union and three cases with nonunion. Prognostic values of age, delay of surgery, fracture type, position of the greater tuberosity and design of implant were assessed. RESULTS: The most important prognostic factor was the design of implant. Mean score of FX Gr was significantly higher than that of TS Gr (84.4 and 77.6 respectively, p=0.036). Age, fracture type, delay of surgery and position of the greater tuberosity did not show any prognostic value. CONCLUSION: The clinical results of Hemiarthroplasty specially designed for the proximal humeral fractures has better than that of preexisting implant. Design of the implant was considered to be the most important prognostic factor of hemiarthroplasty for the proximal humeral fractures.
