Computed tomography (CT) provides an axial image of the dysplastic hip. We reviewed 130 CT scans performed after closed reduction for developmental dysplasia of the hip (DDH) in 42 patients (52 hips). We evaluated methods of measuring CT scans and found no described measurement that was predictive of development of avascular necrosis (AVN) or persistent acetabular dysplasia. The CT scan provides an excellent image of the infant hip when the child is in a spica cast and is useful to confirm an adequate reduction. No patient in this series lost reduction after 2 weeks.
计算机断层扫描（CT）可提供发育不良髋关节的轴向图像。我们回顾了42例患者（52个髋关节）因发育性髋关节发育不良（DDH）行闭合复位后进行的130次CT扫描。我们评估了CT扫描的测量方法，未发现有描述的测量方法可预测缺血性坏死（AVN）或持续性髋臼发育不良的发生。当患儿处于髋人字石膏固定时，CT扫描能提供婴儿髋关节的优质图像，有助于确认复位是否充分。本系列中没有患者在2周后出现复位丢失。
