[Fatigue fracture of the femoral neck following femoral intramedullary nailing].

The course of a fracture of the femur shaft treated in an unstable manner by medullary nailing was full of complications. This handicapped patient can be taken as an example to show the risks involved in the extended intramedullary stabilization using a locking nail on the one hand and, on the other hand, to demonstrate that subsequent fractures induced by therapy can immediately be controlled by simple methods such as additional bolting. Furthermore, the fracture of the femur neck feared as technically or biologically induced consequence of femur nailing in a previously weakened bone can quickly be treated by the relatively simple with osteosynthesis traction screw. This method does not only meet all biomechanical requirements with respect to stability and load-capacity, but has also proved its value in clinical practice when it was applied alone in cervical femur fractures as well as combined with the locking nail in layered fractures of the femur.
