A total of 234 patients （involving 236 hips） with Paprosky III and 1V femoral bone defects were treated with the revision total hip arthroplasty from June 1998 to Aug. 2006. Impaction bone graft technique was used for 112 hips, with allogeneic freeze-dried bone as bone graft and SP II as prosthesis. With 124 hips, modular distal press-fit fixation and tapered femoral stem （MP stem） were employed. After the operation, the subjects were followed up on regular basis and results were assessed by using the Harris Hip Score （HHS） and 12-item Short Form Health Survey （SF-12）. Radiolucence, subsidence and loosening were observed and complications, including infection, fracture, dislocation etc. were recorded. A 6-14-year follow-up showed that prostheses failed, due to infection, in 4 patients of impaction bone graft group and that 6 patients in the press-fit fixation group experienced prosthesis failure, with the survival rates for the two techniques being 96.43% and 95.16%, respectively. One-way ANOVA showed that prosthesis survival was significantly associated with surgery-related complications （P〈0.05） and was not related to the type of the bone defects （P〉0.05）. The rate of complications bore significant association with the type of bone defects in the two groups （P〈0.05）. Our study showed that the two revision methods could achieve satisfactory mid-term and long-term results for the reconstruction of severe bone defects. It is of great significance for attaining high prosthesis survival rate to select suitable operation on the basis of the type of bone defect. Careful operative manipulation and post-operative rehabilitation aimed at reducing complications are also important.展开更多
