A comparative prospective study of dynamic variable angle hip screw and Gamma nail in intertrochanteric hip fractures

Disabil Rehabil. 2005;27(18-19):1157-65. doi: 10.1080/09638280500055875.

Abstract

Purpose: To compare the results between a variable angle dynamic screw-plate(DMS) and the Gamma nail in the treatment of intertrochanteric hip fractures.

Methods: A comparative prospective study of 142 patients (AO/OTA Type 31-A1; A2; A3 and B2) treated by variable angle dynamic screw-plate (DMS Group = 71) or by intramedullary nailing (Gamma Nail Group = 71).

Results: At the 12-month follow-up, we did not find any statistically significant difference, intraoperatively, radiographically, or clinically, between the two groups of patients, except for shortening. In 12 patients in the DMS group (17%) and in one patient in the Gamma nail group, there was shortening of the operated leg between 1 cm and 3 cm (p = 0.02). In all instances, shortening occurred in patients who sustained A.O. type fractures 31A2. 2 and 3 (19 patients), which are unstable and comminuted.

Conclusions: The DMS allows effective management of intertrochanteric fractures of the femur. Surgeons should consider choosing surgical treatment according to the type of intertrochanteric fracture. In less comminuted fractures, a compression hip screw may be a faster and safer surgical solution. In comminuted fractures, surgical difficulties may increase in parallel to fracture complexity.
