During 1986 to 1988 64 patients with the diagnosis acute medial hip fracture have been operated in the University Hospital (Charité) by hip endoprosthesis. Patients up to the age of 75 years have been treated by total hip endoprosthesis. Patients older than 75 years got a femoral head prosthesis. In 92.3% of the patients with femoral head prosthesis no complications were observed. In our hospital we prefer the implantation of the femoral head prosthesis in patients older than 75 years.
