[Management of femoral neck fractures with the spongiosa screw and the dynamic hip screw].

Between 1983 and 1987 419 patients with femoral neck fractures were operated on at the University Clinics of Graz. In 120 patients we could preserve the head of the femur doing an internal fixation with cancellous bone screws or DHS. 68 of them we personally could control with a mean follow up of 45.2 months. The most important complications were the necrosis of the head which were observed in 19.1% of our patients and the non union which occurred in 5.8% but not all these patients required reoperation.
