[Management of combination injuries of the femur shaft and femoral neck fractures with a locking nail. Multicenter study of 26 cases from 4 trauma clinics].

Twenty-six patients with femoral shaft- and ipsilateral neck-fracture, treated in four different hospitals, have been analysed. The majority of these fractures was treated by a distally locked dynamic nail and fixation of the femoral neck by two or three lag-screws. In some cases a "contralateral" nail with a proximal locking screw in the femoral neck was used. Results are excellent without non-union or mal-union. Only one case of avascular necrosis occurred in an 68 years old patient. Interlocking intramedullary nailing certainly has its place in the treatment of associated femoral shaft- and neck-fractures. This closed method presents a stable fixation and permits early mobilisation and joint-function.
