This study was conducted in order to demonstrate the radiologic and clinical results of using the Asian type gamma 3 nail in treatment of trochanteric fractures.

Patients underwent operations with gamma 3 nails between August 2010 and August 2012. For the radiologic evaluation, we analyzed bone quality, fracture pattern, reduction quality, union period, and position of lag screw (tip-apex distance, Cleveland index). For the clinical evaluation, we analyzed mobility score of Palmer and Parker and Jensen's functional score.

The mean union was taken at 17.4 weeks (14-25 weeks). Two cases (4.3%) underwent reoperation due to cutting out of the hip screws. The clinical outcomes of Parker and Palmer's average mobility score changed from 7.3 to 5.8 (79%), Jensen's functional score was 1.3 to 1.8 (72%).

We achieved excellent clinical and radiological outcomes; therefore, Asian type gamma 3 nail is effective in treatment of trochanteric fractures of the femur in Korea.
