Marked acetabular bone loss in revision hip arthroplasty is challenging. Reconstruction or reinforcement rings may be used in moderate or severe cases with morcellised bone graft to restore bone stock. We report a single surgeon series of 45 hips over a 5-year period. There were 6 complex primary and 39 revision hip arthroplasties with a mean follow-up of 85 months (range: 42-106). Mean age at surgery was 75.6 years (range: 31-95). Contour (Smith & Nephew) titanium acetabular rings were used in all cases. At time of assessment 12 patients had died; of the 30 alive patients (33 hips), 23 patients (26 hips) were available for clinical evaluation. Forty of 45 grafts healed uneventfully with good graft incorporation, 2 were radiologically loose and both were infected. No loosening occurred in the absence of infection. Based on this experience, we recommend this as a safe and effective technique with low complication rates.
翻修髋关节置换术中明显的髋臼骨丢失具有挑战性。在中度或重度病例中，可使用重建或加强环并植入粉碎的骨移植材料来恢复骨量。我们报告了一位外科医生在5年期间对45例髋关节进行的手术系列。其中有6例复杂的初次髋关节置换术和39例翻修髋关节置换术，平均随访85个月（范围：42 - 106个月）。手术时的平均年龄为75.6岁（范围：31 - 95岁）。所有病例均使用了轮廓（施乐辉）钛髋臼环。在评估时，有12例患者死亡；在30例存活患者（33髋）中，23例患者（26髋）可进行临床评估。45例移植中有40例顺利愈合，移植骨融合良好，2例在放射学上表现为松动且均伴有感染。在无感染的情况下未发生松动。基于这一经验，我们推荐这是一种安全有效的技术，并发症发生率低。
