Abstract

This paper describes the design principles of a new endoprosthesis made of dense aluminum oxide (Al~2~O~3~) and implanted without bone cement. Mechanical tests and animal experiments have proved the sufficient mechanical strength of the bone–prosthesis connection as well as the biocompatibility of the material. So far, 12 tumor patients selected according to strict indication criteria have been operated on. Both the clinical–radiologic and the first histological findings available are encouraging. Special reference is made to the first fully ceramic total hip joint endoprostheses implanted in a human without bone cement.
