[Initial results with the dynamic hip screw in comparison to other osteosynthesis procedures].

30 fractures of the proximal end of the femur were stabilised with so-called "dynamic hip screws" (AO/ASIF). This method seems to be more suitable for some inter-trochanteric fractures which pose problems questioning our usual treatment with Ender's elastic round nails. The dynamic hip screw system is also more stable for femoral neck fractures of type Pauwels III than 4 cancellous bone screws. One phenomenon which can not yet be fully explained is the slipping out of the screw to an extent unobserved in other procedures.
