[A metal-ceramic composite endoprosthesis for total hip replacement (author's transl)].

A total hip endoprosthesis of our own conception is described. The implantation is done partially without bone cement. The socket and the head are made of alumina whereas the femoral component is of metal. Bone cement is used only for implantation of the shaft. 17 patients on whom operations were performed more than 6 months previously were followed up. The preliminary results are satisfactory. In particular, there were no signs of loosening of the socket. Therefore, this prosthesis is considered to be one step towards a total hip endoprothesis for implantation without bone cement.
