Abstract
The stem of the endoprosthesis comprises a core which provides the necessary strength to the endoprosthesis and a jacket or sleeve of thermoplastic having a softening temperature below 60.degree. C. The jacket can be made flowable upon heating so that during implantation, the jacket can be adapted to the bone cavity. In addition, the jacket can be heated at any subsequent time to return to a plastically deformable state in order to facilitate re-operations.
