摘要(Abstract)：

[目的]研究初次全髋关节置换术后股骨头直径对髋关节脱位的影响,为临床选择理想直径的股骨头假体提供依据。[方法]收集本院和苏州大学附属第一医院骨科自1990年3月~2008年8月期间,采用不同直径的股骨头假体行初次全髋置换术706例(762髋)的病案资料。男性301例,女性405例;年龄21~78岁,平均57岁。术前诊断:股骨头坏死203例,先髋继发骨性关节炎129例(其中Crowe Ⅳ型15例),股骨颈骨折190例,创伤后骨关节炎112例,类风湿强直性脊柱炎58例,结核继发骨性关节炎13例,化脓性髋关节炎融合术后1例。股骨头假体采用22 mm直径者220髋,26 mm直径83髋,28 mm直径459髋。95%手术入路为改良Hard ing入路,5%手术入路为后外侧入路。[结果]全部患者均获得至少6个月的随访,762髋中术后发生脱位28髋,总体脱位率为3.7%。其中股骨头假体直径为22 mm的220髋中,发生脱位者16髋,脱位率为7.3%,股骨头假体直径为26 mm的83髋中,发生脱位4例,脱位率为4.8%,而股骨头假体直径为28 mm的459髋中,发生脱位者8例,脱位率为1.7%。将假体头直径在22、26和28 mm三组脱位率进行统计学分析,发现有统计学差异(x2=13.193,P=0.001;R=0.131,P=0(0.01)。[结论]股骨头直径是影响初次全髋关节置换术后脱位的主要因素之一,直径越大,脱位率越低,反之则脱位率越高。
