[Traumatology in the elderly. Problems exemplified by femoral neck fractures].

The most frequent complications in response to a fracture of the femoral neck, a typical injury of the elderly, are necrosis of the head of femur and pseudoarthrosis of the femoral neck. Only the around dressed down fracture can be conveyed to conservative treatment. The classification of AO takes these problems into consideration. One possibility to preserve the femur head is by operative insertion of a dynamic hip screw (DHS). Specific problems of the diverse types of fracture and their surgical details are taken into special account.
