title: [Cementless Femoral Revision THR after Wagner- Medium-term Results.].
abstract: Authors report on a group of patients operated on in the period 1992-1994. In large bone defects of proximal femur a cementless revision stem of type Wagner was used. The group comprised 13 patients, the most frequent indication was septic loosening of THR handled by a two-phase procedure and aseptic loosening of both components using implants 265 and 306 mm long and with a diameter 14-22 mm. In 12 patients also the cup was revised. Nine patients were checked in 1999 by Harris Hip Score with one excellent result, two good results, three fair and three poor results. Radiograph proved bone ingrowth in all patients as well as secondary biological stabilization of the stem. No signs of stem loosening were found. In 7 patients the stem subsided by maximum 12 mm. The revision of the cementless stem can be considered in certain indications for an alternative of a mere extraction of the implant, i. e. resection arthroplasty with all functional consequences. Therefore the revision stem of type Wagner is still indicated in specific cases. Key words: THR, defects of femur, revision implant.
