[Behaviour of pertrochanteric fractures of the femur after condylar nailing under dynamical stress (author's transl)].

In continuation of our studies on dynamic tolerance after condylar nailing in pertrochanteric fractures, we have examined the femora of patients who died within the first 2 weeks after surgery and studied their stress tolerance. We appreciated the lack of the weight bearing medial cortical bone and the need for abduction at the fracture site by the behaviour under stress. The results under stress could be compared with an experimental fracture model. From these experiments conclusions have been made for the correct placement of condylar nails for their best static advantage.
