[The Judet prosthesis in the treatment of problematic hips (author's transl)].

After an experience of two and a half years with the cementless total hip replacement after Judet we report about the preliminary results in special cases. The implantation of this model of prosthesis is not difficult in case of a good bony stock. We achieved also good results in special indications like in coxarthritis after CDH, hip protrusion and revisions of loosened endoprosthesis. Special techniques are pointed out to enlarge or improve the prosthetic anchorage.
