Abstract

PURPOSE: The purpose of this study is to evaluate the results of treatment of comminuted femoral trochanteric fracture using dynamic hip screw(DHS) with trochanteric stabilizing plate(TSP) and DHS only.
MATERIALS AND METHODS
we analysed retrospectively 32 cases that has fracture extends over two or more levels of medial cortex(A2 of AO classification) and fracture extends through lateral cortex of femur(A3 of AO classicification) of femoral trochanteric fractures between 1997 and 2000. On simple AP radiograph of the DHS with TSP(n=16) and DHS only group(n=16), we reviewed bony union, slippage of lag screw, lateral displacement of greater trochanter. RESULT: Bony union was observed in all cases. When bony union is done in follow up radiograph, Mean slippage of lag screw is 14.5mm in DHS only group, 12.6mm in DHS with TSP group and mean lateral displacement of greater trochanter is 9.8mm in DHS only group, 1.2mm in DHS with TSP group.
CONCLUSION
Use of DHS with TSP in comminuted femoral trochanteric fracture is lesser slippage of lag screw and lateral displacement of greater trochanter than DHS only used, and that is better method to maintain fracture reduction and internal fixation in treatment of comminuted femoral trochanteric fractures than DHS only.
