Cortical bone loss in revision hip arthroplasty requires an adequate stabilization to achieve a durable implant fixation. This case series shall illustrate possible indications for the use of allogenic grafts in revision hip arthroplasty. Twelve patients with femoral bone loss were treated with allografts. In addition to established clinical scores, the radiological follow-ups were analyzed for hints of implants loosening and the osteointegration of the allografts. After a mean follow-up of 3.0 years the mHHS was 61.3 points and the UCLA 3.8. One patient showed a non-progressive radiolucency around the hip implant. The osteointegration of all allogenic grafts happened on time. Up to the last follow-up no revision surgery of the hip implants and the associated femoral bone graft was observed. Allogenic bone grafts present a method for biological stabilization in situations of large femoral cortical bone defects in revision hip arthroplasty.
髋关节翻修术中的皮质骨丢失需要充分稳定以实现持久的植入物固定。本病例系列将说明同种异体移植物在髋关节翻修术中的可能适应证。12例股骨骨丢失患者接受了同种异体移植物治疗。除了既定的临床评分外，还对影像学随访进行了分析，以寻找植入物松动和同种异体移植物骨整合的迹象。平均随访3.0年后，改良Harris髋关节评分（mHHS）为61.3分，加州大学洛杉矶分校（UCLA）评分3.8分。1例患者在髋关节植入物周围出现非进行性透光影。所有同种异体移植物均按时发生骨整合。直至最后一次随访，未观察到髋关节植入物及相关股骨骨移植的翻修手术。同种异体骨移植为髋关节翻修术中股骨皮质骨大缺损情况下的生物稳定提供了一种方法。
