摘要 目的:探讨成人髋关节发育不良(developmental dysplasia of the hip,DDH)患者股骨近端CT三维重建的形态差异和临床意义。方法:通过CT重建测量72例DDH患者(78髋)与54例(54髋)正常股骨近端参数,包括股骨头直径、股骨头高度、头心-干轴距、颈干角、股骨颈前倾角,按Crowe分型标准分为3组,组1:CroweⅠ型(23髋),组2:CroweⅡ型(31髋),组3:CroweⅢ型和Ⅳ型共24髋,分别比较3组和正常对照组股骨近端的形态差异。结果:DDH3组均与正常股骨近端形态均有差异,组1股骨头高度[(4.84±0.57)cm]较对照组[(4.45±0.47)cm]高(P=0.013);组2、组3头心-干轴距分别为(2.66±0.85)cm和(2.39±0.77)cm,均较对照组[(3.16±0.51)cm]小(P均<0.05);DDH组头心-干轴距随着髋脱位程度增加而逐渐减小。结论:DDH患者股骨近端存在形态异常,在全髋关节置换术前行髋关节的CT扫描和三维重建对术中股骨柄假体的选择和安放角度有指导意义。
