摘要(Abstract)：
[目的]研究三维CT辅助下大龄发育性髋关节脱位的个体化手术治疗临床效果。[方法]对31例年龄7～13岁大龄发育性髋关节脱位患者进行三维CT辅助下个体化手术治疗,根据三维CT测量数据选择具体截骨方式,应用三维CT测定数据及Mackay评定标准进行评定。[结果]随访2～7年,平均5.2年。McKay髋关节评定结果:优15髋(42.9%)、良16髋(45.7%)、差4髋(11.4%),优良率88.6%。无感染或骨不连。术后发生股骨头坏死1例。术前髋臼角为26.1°～40.2°,平均32°;术前髋臼覆盖股骨头百分比-10%～55%,平均-0.5%;术后髋臼角为15.5°～25.0°,平均19.5°;术后髋臼覆盖股骨头百分比98%～112%,平均104%。[结论]三维CT辅助下个体化手术治疗对于大龄DDH的治疗效果满意。
