title: Fractures of the proximal femur in patients with total hip endoprostheses.
abstract: Between October 1982 and October 1983 three patients were admitted to the Orthopedic Clinic of the University of Vienna who had suffered complicated fractures of the proximal femur, with concomitant loosening of previously implanted total hip endoprostheses. To replace them we used the KMFTR Endoprosthesis. The Kotz Modular Femur and Tibia Reconstruction Endoprosthesis was originally developed for the surgical management of bone tumors. The implantation followed the principle of intramedullary splinting and transfer of force. Fragments of bone adhering to the surrounding muscles were positioned around the endoprosthesis and the periosteum was carefully reconstructed. After a follow-up period of 1 year on the average the patients were very content with the results and were essentially not restricted in their scope of activities. Walking capacity and mobility were satisfying at last checkup. Radiographically, a consolidation of the femur with solid bony incorporation and a firm fit of the prosthesis were observed.
