摘要(Abstract)：

[目的]分析髋关节置换骨水泥型股骨假体周围水泥鞘的质量和厚度。[方法]回顾北京大学第三医院骨科自2004年2月-2007年12月采用相同入路、操作技术和假体完成的262例(279髋)初次髋关节置换病例,分析术后出院前X线片,对股骨侧骨水泥鞘质量和厚度进行分析。[结果](1)按Barrack标准,骨水泥质量A级87.1%,B级11.8%,C级1.1%,无D级骨水泥;(2)按Gruen分区,骨水泥鞘厚度<2mm区域多见于正位片上1、2、5区和侧位片上8、9、12区;透亮带多位于假体中远端的2～5区和10～12区;气泡影出现在假体远端的3～5区和10～12区。(3)股骨假体和股骨解剖轴线在正位片上的夹角,在骨水泥鞘厚度>2mm组中为1.46°±0.75°(-1.60°～3.41°);在骨水泥鞘厚度<2mm区域组中为3.90°±1.52°(-2.99°～7.69°),两组间差异有统计学意义(P<0.05)。[结论]正确使用第3代骨水泥技术,可获得可靠的骨水泥固定质量。股骨假体应参考股骨解剖轴线中立位置入,以期获得均匀一致,足够厚度的骨水泥鞘。
