[Using of a Wagner stem in revision-arthroplasty following loosening of a total hip endoprosthesis].

During a three-year period to 50 patients a Wagner femoral revision endoprosthesis was implanted. The mean age of the patients was 67.5 years. In 39 patients replacement of an endoprosthesis was involved, in 7 patients the indication was fracture in the area of the endoprosthesis, 4 patients were operated for other reasons. Of 44 patients, who were operated at least 12 months ago, 33 were checked. Sixteen patients were classified according to Harris' score as very good, 9 as good and in 4 the result was satisfactory or poor. Wagner's revision shank is suitable in particular in damage of the proximal femur, where in case of firm distal anchoring and early ability to burden the extremity proximally, marked new formation of bone was observed with restoration of the pipe-shaped bone structure.
