To evaluate the radiologic, clinical results between who had intertrochanteric fracture, treated with Compression Hip Screw (CHS) and Proximal Femoral Nail Antirotation (PFNA).

We retrospectively reviewed each 36 and 48 patients of intertrochanteric fracture which were treated with CHS or PFNA by one surgeon from January 2005 to June 2009. We evaluated mean operation time, amount of bleeding, radiologic results, and the clinical outcomes with the mobility score of Parker and Palmer, social function scoring system.

The mean operation time, amount of bleeding were less in the PFNA group, there were 116.7 min, 486.1 ml for the CHS group versus 87.7 min, 289.6 ml for the PFNA group. The radiologic results were not significantly different. Decrease of mobility score of Parker and Palmer, social function score were similar. Proximal migration of leg screw and perforation of femoral head was 2 case and deep infection was 1 cases in CHS group.

There were no significant differences that are clinical and radiological results in treatment of intertrochanteric fracture using the CHS and PFNA. But PFNA is less invasive device than CHS, therefore it may be useful device in elderly patients.
