In twenty-one hips of twenty-one patients, the acetabulum was reconstructed using allografts during revision of a total hip arthroplasty. The patients' average age at the time of revision was 64.3 years (range, nineteen to eighty-six years). At an average follow-up of 3.5 years (range, two to five years), three patients had died of causes unrelated to the hip reconstruction, and one had been lost to follow-up. In the other seventeen, the average Harris hip rating was 89 points (range, seventy to 100 points) at follow-up. In one patient the allograft collapsed, so that revision was required. Two patients had asymptomatic progressive radiolucencies at the cement-bone interface of the reconstructed acetabulum, and another had a 1.5-millimeter-wide lucency at the interface of the donor and recipient bone but was asymptomatic, and there had been no change in the position of the cemented acetabular component since operation. The remaining grafts appeared to be incorporated securely, as determined by radiographic examination. Three-dimensional computerized tomographic radioisotopic bone scans showed uniform uptake, consistent with revascularization and new-bone formation, in all grafts. There was no radiographic evidence of focal avascularity and there were no infections. Femoral-head bone allografts appear to provide a useful technique for the reconstruction of a severely deficient acetabulum during revision total hip arthroplasty.
在21例患者的21个髋关节中，全髋关节置换翻修术中使用同种异体骨移植重建髋臼。翻修时患者的平均年龄为64.3岁（范围19至86岁）。平均随访3.5年（范围2至5年），3例患者死于与髋关节重建无关的原因，1例失访。在其余17例中，随访时Harris髋关节评分平均为89分（范围70至100分）。1例患者的同种异体骨塌陷，因此需要再次翻修。2例患者在重建髋臼的骨水泥-骨界面出现无症状的进行性透亮线，另1例在供体和受体骨界面有1.5毫米宽的透亮线，但无症状，自手术以来骨水泥固定的髋臼假体位置无变化。根据影像学检查，其余移植骨似乎已牢固融合。三维计算机断层放射性核素骨扫描显示所有移植骨摄取均匀，与血管再生和新骨形成一致。没有局灶性缺血的影像学证据，也没有感染。在全髋关节置换翻修术中，股骨头同种异体骨移植似乎为严重缺损髋臼的重建提供了一种有用的技术。
