摘要 目的估价髋关节置换术中照相在判断股骨假体的位置及型号的作用。方法两组髋关节置换术,A组为术中照相组,B组为无照相组。各组分别混合采用两种不同厂家的假体,术前采用模板技术,均采用外侧入路。A组在术中照相判断股骨试模的位置和股骨试模颈基底与小转子尖的距离。结果两组均无感染,A组手术平均时间为75min,B组平均为58min。双下肢长度差异A组为2mm,B组为9mm,两者有显著性差异;A组颈干角均在130°~150°,B组有4例颈干角在135°~140°,3例在120°~125°。A组有1例术中骨折,B组有3例术中骨折。结论非骨水泥型髋关节置换术中照相是解决假体内外翻、假体周围骨折、双下肢不等长的一种有效方法。
