Failure of total hip arthroplasty with acetabular deficiency occurred in 55 patients (60 hips) and was treated with acetabular revision using morsellised allograft and a cemented metal-backed component. A total of 50 patients (55 hips) were available for clinical and radiological evaluation at a mean follow-up of 5.8 years (3 to 9.5). No hip required further revision of the acetabular component because of aseptic loosening. All the hips except one had complete incorporation of the allograft demonstrated on the radiographs. A complete radiolucent line of > 1 mm was noted in two hips post-operatively. A good to excellent result occurred in 50 hips (91%). With radiological evidence of aseptic loosening of the acetabular component as the end-point, the survivorship at a mean of 5.8 years after surgery was 96.4%. The use of impacted allograft chips in combination with a cemented metal-backed acetabular component and screw fixation can achieve good medium-term results in patients with acetabular bone deficiency.
55例患者（60髋）出现全髋关节置换术合并髋臼缺损失败，采用异体骨碎骨块及骨水泥固定金属背衬组件进行髋臼翻修治疗。共有50例患者（55髋）可进行临床和影像学评估，平均随访5.8年（3至9.5年）。没有髋关节因无菌性松动而需要进一步翻修髋臼组件。除1例外，所有髋关节在X线片上均显示异体骨完全融合。术后2髋出现>1mm的完整透亮线。50髋（91%）结果为良好至优秀。以髋臼组件无菌性松动的影像学证据为终点，术后平均5.8年的生存率为96.4%。使用打压异体骨碎骨块联合骨水泥固定金属背衬髋臼组件及螺钉固定，可在髋臼骨缺损患者中取得良好的中期效果。
