The purpose of this study was to evaluate the clinical and radiographic outcomes revision femoral component a hip arthroplasty with use an impaction bone-grafting technique cemented polished stem.Thirty-three consecutive reconstructions that were performed between March 1991 February 1996 X-change system, fresh-frozen morselized allograft, Exeter stem followed prospectively. Femoral bone stock defects classified according Endoklinik classification. average age patients at time sixty-three years. No patient lost follow-up, which minimum eight years, but had died. None deaths related surgery.No reconstruction been rerevised mean 10.4 years postoperatively. There one unrecognized intraoperative fracture, healed following nonoperative treatment. three postoperative fractures, all through cortical level tip prostheses. All fractures after plate fixation, implants left in situ. subsidence within cement mantle 3 mm; seven stems migrated > or =5 mm. Harris score improved from 49 points prior surgery 85 (range, 68 100 points) review. Subsidence did not affect score. Kaplan-Meier analysis, end point for any reason, showed survival rate 100% (one-sided 95% confidence interval, 91.3%).Femoral resulted excellent prosthetic thirteen major problem occurred fracture four patients.
