| 摘 要： | 目的分析CT股骨头覆盖率在儿童发育性髋脱位（DDH）Salter手术前后的诊断价值。方法选取38例行Salter手术的单侧DDH患儿，Salter术前1周和术后6个月进行骨盆正位X线摄片及髋关节螺旋CT扫描，计算并比较X线片股骨头覆盖率及CT股骨头覆盖率。以38个儿童正常髋关节为对照组。结果DDH组术前X线片股骨头覆盖率高于CT股骨头覆盖率（P〈0．01）。对照组CT股骨头覆盖率前部最高，中后部相对较低。DDH组术前CT股骨头覆盖率低，前部更加显著；术后CT股骨头覆盖率接近正常。结论CT股骨头覆盖率能立体反映髋臼与股骨头的发育状况，并对Salter手术近远期效果进行评价，进而指导临床治疗。

| Abstract: | Objective To analyse the femoral head coverage rate of CT in evaluation of Salter osteotomy for developmental dislocation of hip(DDH) in children. Methods Thirty-eight patients with unilateral DDH for Salter osteotomy were enrolled,and X ray photography of pelvis and spiral CT scanning of femoral articulation were performed one week before and 6 months after Salter osteotomy.The femoral head coverage rate of X ray and that of CT were calculated and compared.Another 38 children with normal femoral articulati... |
