Purpose: The purpose of this study is to evaluate the results of bipolar hemiarthroplasty using calcar replacement stem for comminuted intertrochanteric fracture in elderly patients.
Materials and Methods: Between March 1998 and March 2008, the clinical records of 79 cases who were older than 75 years of age and underwent bipolar hemiarthroplaty, using calcar replacement stem with figure of eight and cerclage wiring, were reviewed. Their mean age was 82.4 years(75-92 years) and the mean follow-up period was 68 months(24-92 months).
Results: The mean postoperative Harris hip score was 82.1(62-92), and preoperative walking ability was recovered in 56 cases(71%). Bony ingrowth fixation was achieved in 70 cases(89%), and fibrous stable fixation was in 9 cases(11%). Stress shields were revealed in 21 cases(27%). Nonunion of trochanter was found in 3 cases(4%), and wire fixation breakages were in 3 cases after bony union. The mean duration of bony union was 16.3 weeks(12-38 weeks). Aseptic loosening was observed in 1 case and protrusio acetabuli were in 2 cases.
Conclusion: The result of clinical and radiological evaluations of bipolar hemiarthroplasty, using calcar replacement stem with figure of eight and cerclage wiring, were satisfactory in elderly patients with comminuted intertrochanteric fracture.
