ABSTRACT

Objective To compare the clinical results of the intramedullary nails (Gamma nail and the proximal femoral nail) in treatment of intertrochanteric fractures of femur. Methods A review study was conducted on 116 intertrochanteric fractures of femur treated with the Gamma nail and 89 treated with PFN in our hospital between 2000 and 2003. Results In the Gamma nail group, the mean time for operation was 68.3(48 to 106)minutes,the mean blood loss during operation was 261(180 to 400)mL,the mean time for walking after operation was 5.0 (2.3 to 8.9)weeks and the mean time for bone union was 8.6(7.1 to 12.6)weeks. In the PFN group, the mean time for operation was 48.0(36 to 85)minutes, the mean blood loss during operation was 192(120 to 360)mL,the mean time for walking after operation was 5.3(2.5 to 8.1)weeks and the mean time for bone union was 8.8(6.9 to 12.1)weeks. There were significant differences in the mean time for operation and the mean blood loss between the 2 groups(P
