The senior authors have performed 141 proximal femoral whole-bone allografts in failed total hip reconstruction. The results of the first 50 have been previously reported. This study reviews 70 additional cases performed since 1987 and reflects improved technique and several different junctional constructs. Modest improvements in the rate of union (64% v 80%) and of dislocation (28% v 16%) have been achieved. The infection rate (6% v 4%) and demographics of the groups have remained constant. The frequency of complications (67% v 53%) has decreased, but unfortunately remains high. A step-out allograft junction with a long lateral sleeve has been the most reliable construct.
资深作者已在髋关节翻修失败的病例中进行了141例股骨近端全骨同种异体移植。前50例的结果已在之前报道过。本研究回顾了自1987年以来另外70例病例，并反映了技术的改进以及几种不同的连接结构。骨愈合率（64%对80%）和脱位率（28%对16%）有适度改善。两组的感染率（6%对4%）和人口统计学特征保持不变。并发症发生率（67%对53%）有所下降，但遗憾的是仍然很高。带有长外侧套管的阶梯状异体骨连接是最可靠的结构。
