The presence of femoral deficiencies in revision total hip arthroplasty may contribute to loosening, subsidence, and fracture. Between 1984 and 1990, 174 patients were treated with revision total hip arthroplasty, preformed by a standardized operative technique using cortical onlay strut allografts to restore the structural integrity of the femur and a calcar deficient proximally porous coated femoral prosthesis, composed of titanium alloy. The grafts united 98% of the time and showed evidence of revascularization and, in some cases, complete incorporation. Cortical onlay strut grafting in conjunction with a proximal load- bearing prosthesis is a viable method of reconstructing the structurally deficient femur in revision total hip arthroplasty.
翻修全髋关节置换术中股骨缺损的存在可能导致假体松动、下沉和骨折。1984年至1990年间，174例患者接受了翻修全髋关节置换术，采用标准化手术技术，使用皮质骨贴附支撑异体骨移植来恢复股骨的结构完整性，并使用近端多孔涂层钛合金股骨假体来处理小粗隆缺损。移植骨98%实现愈合，显示有血管再生迹象，在某些情况下完全融合。在翻修全髋关节置换术中，皮质骨贴附支撑骨移植联合近端承重假体是重建结构缺损股骨的一种可行方法。
