PURPOSE: To compare the timing of ambulation, complications and functional results between the autogenous femoral head graft and the calcar replacement type stem in the severe comminuted fracture of the elderly patients with unstability. MATERIALS AND METHODS: 25 intertrochanteric femoral fracture patients who had bipolar hemiarthroplasty were followed for more than 1 year. 17 patients had autogenous femoral head graft and 8 patients had calcar replacement type stem. RESULT: The mean operating time for autogenous femoral head graft was 1.7 hours, and calcar replacement type stem was 1.3 hours. Postoperative Harris functional score was 84.1 for the autogenous femoral head graft group and 82.2 for the calcar replacement type stem group. Discussion : Both autogenous femoral head graft augmentation and fixation using the calcar replacement type stem result in rigid fixation, which enables the patients to ambulate early and to have low complication rate. Both techniques seem to be effective for the treatment of intertrochanteric fractures.
