我们回顾了71例全髋关节置换术中使用同种异体骨植入的髋臼假体翻修的结果。平均随访时间为7.2年（1.6 ~ 9.7年）。所有患者均根据美国骨科医师学会（AAOS）的骨质流失分类、所需植骨量、植骨层厚度、植骨融合迹象和隆胸使用情况进行评估。共有20个髋臼部件因无菌性松动需要重新翻修，总生存率为72% （95% CI, 54.4 - 80.5）。在这些失败中，14例（70%）有AAOS III型或IV型骨缺损。失败组放射学和组织学上可见移植物融合不良。这些结果表明，严重骨缺损的髋臼翻修中同种异体嵌塞移植的效果可能比以前报道的要差。
We reviewed the results of 71 revisions of the acetabular component in total hip replacement, using impaction of bone allograft. The mean follow-up was 7.2 years ( 1.6 to 9.7). All patients were assessed according to the American Academy of Orthopedic Surgeons ( AAOS) classification of bone loss, the amount of bone graft required, thickness of the graft layer, signs of graft incorporation and use of augmentation.A total of 20 acetabular components required re-revision for aseptic loosening, giving an overall survival of 72% ( 95% CI, 54.4 to 80.5). Of these failures, 14 ( 70%) had an AAOS type III or IV bone defect. In the failed group, poor radiological and histological graft incorporation was seen.These results suggest that impaction allografting in acetabular revision with severe bone defects may have poorer results than have previously been reported.
