Impacted bone allografts and a cemented stem after failure of an uncemented stem: preliminary results.
We reviewed the results of impaction bone grafting technique and a cemented stem in 27 consecutive patients with a failed uncemented femoral component. At an average follow-up of 55 months (25 to 94) none of the femoral components were removed or revised because of aseptic loosening or deep infection. In one hip a non progressive radiolucent line was observed in Gruen zone 5 with no clinical evidence of failure. The average postoperative Merle d'Aubigné and Postel Hip Score was 5.8 points for pain, 5.5 points for mobility and 5.4 points for gait. Revision of a failed uncemented stem with impaction grafting technique provided pain relief and improved function. The rate of success and restoration of bone stock were encouraging at mid-term follow-up.
