This article summarises a clinical and radiographical analysis of 30 acetabular revisions in patients younger than 55 years old, performed with impaction bone grafting and cemented cups. Preoperative Merle D'Aubigne and Postel functional score was an average 7 points. At a mean follow-up of 86.5 months (range 34-228) functional score averaged 16.3 points. Radiolucent lines with no clinical impact were observed in 7% of DeLee and Charnley acetabular zones evaluated. Massive radiological migration, consistent with clinical failure, was observed in two cups. Three patients underwent re-revision surgery (10%): two due to infection and one due to mechanical failure. Reconstruction survival rate was 89% (CI 95% 71.9-96.4) overall, and 96% (CI 95% 82.6-99.3) ruling out cases of infection. Impacted bone allograft constitutes one of the reconstructive techniques of choice in acetabular revision surgery of young patients. Restoration of bone stock is essential in this group of patients due to the possibility of future revisions.
本文总结了对55岁以下患者进行的30例髋臼翻修术的临床和影像学分析,这些手术采用了打压植骨和骨水泥杯。术前Merle D'Aubigne和Postel功能评分平均为7分。平均随访86.5个月(范围34 - 228个月)时,功能评分平均为16.3分。在评估的DeLee和Charnley髋臼区域中,7%观察到无临床影响的透亮线。在两个髋臼杯中观察到与临床失败一致的大量影像学移位。3例患者接受了再次翻修手术(10%):2例因感染,1例因机械故障。总体重建生存率为89%(95%置信区间71.9 - 96.4),排除感染病例后为96%(95%置信区间82.6 - 99.3)。打压异体骨移植是年轻患者髋臼翻修手术中首选的重建技术之一。由于未来可能需要再次翻修,恢复骨量在这类患者中至关重要。
