- Abstract: PURPOSE: The purpose of this article is to evaluate the result of treatment of unstable intertrochanteric fractures by lateralization of distal fragment and antero-medial cortex contact of the distal shaft piece. MATERIALS AND METHODS: We conducted an analysis of 20 cases of unstable intertrochanteric fractures treated using a gamma-3 nail from August 2011 to August 2012 and followed up for more than one year. Using postoperative and last follow-up radiographs, we measured NSA, TAD, Cleveland index, sliding length of the lag screw, and union time. Adequacy of reduction was assessed by a modification in the criteria of Baumgaertner and classified as good, acceptable, or poor. RESULTS: The mean NSA was 140degrees postoperative and 135degrees at last follow-up. The mean TAD was 11.3 mm. The position of the lag screw was in center-center in 12 cases, center-inferior in eight cases. The mean distance of lag screw sliding was 5.5 mm at last follow-up. The mean union time was 3.7 months. The state of reduction postoperatively was good in 15 cases, and acceptable in five cases. There was no failure of reduction, lag screw cut-out, or other complications at last follow-up. CONCLUSION: The reduction method for lateralization of distal fragment and antero-medial cortex contact of the distal shaft piece in an unstable intertrochanteric fracture is very useful for prevention of collapse of the fracture site, lag screw cut-out, and mechanical failure.
