摘　　要：背景:目前国内外学者已经运用螺旋CT三维重建技术,对发育性髋关节脱位患儿髋臼股骨头覆盖率进行观察,但报道多为某一时间点的观察研究,缺乏3年或更长期的连续跟踪随访及综合分析,作者的研究填补了这一空白。目的:螺旋CT三维重建下,连续跟踪观察发育性髋关节脱位患儿经保守治疗后3年内髋臼股骨头覆盖率的变化特点。方法:选择73例行手法闭合复位铝支架固定的单侧发育性髋关节脱位患儿,整复前1d和整复后12,24,36个月分别行髋关节螺旋CT三维重建扫描,测量髋臼股骨头平均覆盖率动态变化。以患儿正常侧髋关节为对照进行对比观察。结果及结论:随访时间为3年6个月～4年5个月,65例患儿进入结果分析。闭合复位后患髋髋臼股骨头覆盖率均显著高于治疗前(P<0.01),随访3年内逐渐接近正常,其中治疗后1年内是髋臼发育塑性的关键时期。BACKGROUND： Spiral CT three-dimensional reconstruction has been used to observe the femoral head coverage fate of developmental dislocation of the hip （DDH）. However, most of research containing certain observing point, which lack of long-term follow-up and comprehensive analysis. This article wants to fill the gaps. OBJECTIVE： To study changes of femoral head coverage fate in DDH child after 3 years treatment by CT reconstruction. METHODS： Totally 73 patients with unilateral DDH treated by aluminium plate after manual close reduction was selected. Spiral CT scanning of femoral articulation was performed at 1 day before and 12, 24, and 36 months after reduction to measure the femoral head coverage fate changes. The normal hip of patient was served as control. RESULTS AND CONCLUSION： All patients were included in the 42-53 months follow-up. After treatment, the femoral head coverage fate of patients were obviously than that of before treatment （P 0.01）, which gradually approach to the normal level in 3 years, the first year after treatment is a key period for acetabulum development.
