摘要(Abstract)：
目的:探讨在髓臼发育不良的病例行人工全髋关节置换术时人工髋臼安放的方法。方法:对15例22个因髋臼发育不良导致骨关节炎的病例,在行人工全髋关节置换术时,根据髋臼发育不良的程度,采用了髋臼外上缘植骨,加深髋臼及髋臼轻度内陷等三种方法。术后3、6、9、12个月及以后每半年以同等条件投照双侧髋关节正位X线片,观察人工髋臼安放的角度及人工髋臼与髋臼骨床愈合的情况。平均随访24个月。结果:随访时发现加深髋臼及髋臼轻度内陷的病例,人工髋臼与髋臼骨床接触良好,角度满意,关节功能恢复优良。而髋臼外上缘植骨的病例,术后2年时植骨块与人工髋臼之间出现了透亮带。结论:髋臼发育不良导致髋关节骨关节炎的病例在施行人工关节置换术时应根据髋臼骨床的情况采用不同的手术方式安放人工髋臼。特别是在髋臼较浅,而髋臼骨床底部骨质较多的情况下,应采用向内切磨髋臼,加深髋臼后安放人工髋臼。本组病例大部分采取此方法,收到了十分满意的临床效果。但手术中应注意不宜切磨髋臼过深,影响到髋臼内壁的稳定。
