Most of femur intertrochanteric fractures occured in elderly patients with predisposing osteoporotic bone change and general weakness. This group is exposed to the high postoperative morbidity and mortality. Many devices were developed for these purposes, Gamma nail is relatively acceptable on above considerations because of some benefits; lower blood loss, lower risk of infection, shorter operation time, early weight bearing and rigid internal fixation. We reviewed 19 cases of compression hip screw fixation(group 1) from March 1990 to October 1991 and 19 cases of unreamed type Gamma nail (group 2) from March 1990 to May 1993. The following results were obtained; 1. The mean union time was 15.1 weeks on group 1 and 15.4 weeks on group 2. 2. The mean amount of intraoperative bleeding was 511ml on group 1 and 303ml on group 2. 3. The mean timing of nonweight bearing ambulation was at postoprative 5.3 days on group 1 and at 2.2 days on group 2. 4. The complications were 4 cases on group 1 and 3 cases on group 2. 5. We obtained satisfactory results in femur intertrochanteric fracture using unreamed type Gamma nail. So, We suggest application of this method for treatment of femur intertrochaneric fracture if skilled technique is used.
