目的研究骨水泥假体柄与股骨界面应力传递的力学模型。
Objective To study the modeling stress transfer at the interface of cemented prosthesis and femur.
目的建立人工髋关节置换术后的三维有限元模型，分析研究人工股骨柄、骨水泥和人体股骨的应力分布。
Objective a three dimensional finite element model after total hip replacement was established to analytically study the stress distribution of the artificial stem, bone cement and human femur.
锥度减小设计为高抛光的锥形柄，允许假体柄在骨水泥套中下沉并再度获得稳定性。
The taper slip is a highly polished tapered stem designed to settle within the cement mantle and re-engage the taper.
结果：在关节置换组，仅使用当代的双极假体，采用羟基磷灰石涂层现代柄非骨水泥假体占20.8%(522人)。
Results in the arthroplasty group, only contemporary bipolar prostheses were used and uncemented prostheses with modern stems and hydroxyapatite coating accounted for 20.8% (522) of the implants.
大粗隆延长截骨在髋翻修手术中可以帮助充分暴露术野，取出固定良好的骨水泥和非骨水泥股骨柄，同时截骨愈合良好。
Extended trochanteric osteotomy is useful in hip joint revision. After osteotomy femoral prosthesis and cement could be taken out easily, and the osteotomy site could be healed easily.
