摘要
目的 评价成人髋臼发育不良(acetabulardysplasia,AD)的CT测量诊断方法及临床意义。方法 对33例成人AD及210例正常成人髋关节CT图像进行对照测量研究。结果 AD组与正常成人组股骨头内间隙分别为(1003±232)mm和(706±127)mm,前后唇长度之和分别为(375±072)cm和(510±051)cm,前后唇长度之和与股骨头直径比值分别为090±014和112±010,顶唇长度分别为(331±046)cm和(454±038)cm,顶唇长度与股骨头直径比值分别为085±011和101±006,前唇头距分别为(632±183)mm和(410±133)mm,后唇头距分别为(502±145)mm和(360±080)mm,臼头距分别为(978±305)mm和(534±234)mm,股骨头覆盖率为(3364±856)%[男(5003±695)%、女(5360±702)%],Sharp角分别为(4688±611)°和(3575±360)°,两组间指标的差异具有显著性意义(P<001)。并提出了各项指标的正常值。认为“光头征”及托球征”为成人AD的直接CT征象。结论 CT测量诊断成人AD优于X线平片,能直接测量髋臼各唇的长度,了解髋臼各部分的发育状况,可作为一种常规检查方法。
