摘　　要：目的探讨髋脱位儿童髋臼容积的测量及意义。方法应用CT技术,测量正常组(34髋)和异常组(36髋)的髋臼容积、股骨头体积。结果正常组儿童的髋臼容积较脱位组明显增大,二者直线回归方程的截距差异有统计学意义。结论髋关节脱位的患儿髋臼发育差,与股骨头呈现明显的不匹配;早期手法复位时髋臼容积可以作为测量指标。手术复位前也应了解髋臼容积的变化。Objective To assess the relationship between acetabular volume and the developmental dysplasia of the hip. Methods We measured the volumes of the acetabular and the head of femur with computed tomography scans in 34 normal hips and 36 abnormal hips. Results We found the acetabular volume was decreased in the abnormal hips. There was statistically significant difference between the two groups （linear regression）. Conclusions The development of acetabular in developmental dysplasia of the hip differed form that of the normal hip. The acetabular did not fit the head of fe- mur. Measurement of the acetabular volume can be useful in early reduction.
