This article reports the results of 181 cemented revision total hip arthroplasties in which impacted morcellized allograft and cement was used for reconstitution of acetabular and femoral bone deficiencies. There were 173 acetabular and 79 femoral reconstructions. The mean follow-up was 4.0 years. The overall survival rate was 97.2%. Evidence of revascularization of the impacted allograft was shown in 29 of 30 (97%) randomly selected bone scintigraphies. Radiographic evidence of allograft incorporation was observed in 128 of 173 (74%) acetabula and 48 of 73 (61%) femora. Stem subsidence occurred in all types of femoral bone deficiencies and was not time dependent (P =.17). The acetabular components showed significant migration with increased bone deficiency (P =.0003). Impaction bone grafting has shown promising results in revision total hip arthroplasty but is not recommended in type 3 acetabular defects.
本文报告了181例使用骨水泥的全髋关节翻修术的结果，其中使用了打压植骨的异体骨碎骨块和骨水泥来重建髋臼和股骨骨缺损。有173例髋臼重建和79例股骨重建。平均随访时间为4.0年。总体生存率为97.2%。在随机选择的30例骨闪烁显像中，有29例（97%）显示打压植骨异体骨有血管化迹象。在173例髋臼中的128例（74%）和73例股骨中的48例（61%）观察到异体骨融合的影像学证据。所有类型的股骨骨缺损均出现假体下沉，且与时间无关（P = 0.17）。髋臼假体随着骨缺损增加出现明显移位（P = 0.0003）。打压植骨在全髋关节翻修术中已显示出有前景的结果，但不推荐用于3型髋臼缺损。
