[The dynamic hip screw support plate for management of unstable proximal femoral fractures].

The DHS-Implant system is a technically simple and widely used operative treatment modality for pertrochanteric fractures of the femur. In unstable 4 part-fractures rotation of the head and neck fragment around the lag screw and a significant impaction might lead to a lateralisation of the greater trochanter and therefore to an important shortening. To prevent these effects we treated 17 patients with 4 part-fractures with a prototype of a modular trochanteric DHS buttress plate. With this additional implant the lateralisation of the greater trochanter could be prevented in all cases. This also leads to a limitation of the telescoping, with less shortening even with immediate full weight bearing.
