Abstract

It has been emphasized that the treatment of choice for the trochanteric fracture of the femur is open reduction and rigid internal fixation. Regarding the stability of the fracture, most reports were focused on the comminution of the medial cortex, but few reports were paid attention to the additional fracture of the greater trochanter. This paper was aimed to evaluate the fragment of the greater trochanter on the maintenance of reduction. We treated 23 cases of unstable trochanteric fractures in which 16 cases were treated with Dynamic Hip Screw (DHS) alone, and 7 cases were treated with DHS and additional DHS Trochanter Stabilizing Plate (TSP). We compared the two groups and the results were as follows: 1. The average lag screw slipping distance was 17.1mm in DHS Group and 10.0mm in TSP Group. 2. The average distance of lateral displacement of greater trochanter over the trochantric fractures was 11.5mm in DHS Group and no change in TSP Group. The above results suggested that the comhined use of DHS Trochanter Stabilizing Plate with Dynamic Hip Screw provided good results in the treatment of uristable intertrochanteric fractures with completely detached greater trochanter and reverse oblique fracture.
