[Necrosis of the head of the femur as a complication of the medial fracture of the neck of the femur (author's transl)].

In spite of the progress achieved in accident surgery, medial fractures of the neck of the femur still present a lot of problems. The rate of success achieved in most other cases of bone fracture is not obtained here. The necrosis of the head is the most frequent and most serious complication of the medial fracture of the neck of the femur. Its formation is influenced by different factors, such as fracture line, dislocation of the fragments, time and method of reposition, and method of osteosynthesis. A prognosis whether a necrosis of the head of the femur is to be expected or not can be made when these factors are taken into consideration. So, by means of a primary alloarthroplasty, it will be possible to spare the patient a later reconstruction.
