Both hip joints in 156 children, aged 2 months to 2 years, were examined by ultrasonography (ultrasound) and radiography. Pathologic findings were based on an increased acetabular index, bony defects of the lateral acetabular rim, and lateral and/or proximal displacement of the proximal femur. Each hip was classified as normal, dysplasia, subluxation, or dislocation. The same diagnosis was reached by ultrasound and radiography in 303 of the 312 hips. The accordance was good in normal joints, in subluxation, and in dislocation. However in 7 of the 15 hips with radiographic dysplasia, ultrasound was normal. These patients were not treated, and spontaneous normalization or improvement occurred in all of them. One parameter only, the distance from the lateral margin of the ossification center of the femoral head to Perkins' line, was measured by both ultrasound and radiography; the correlation was high (r = 0.73). We recommend ultrasound as the primary imaging technique when congenital dislocation is suspected clinically.
对156名年龄在2个月至2岁的儿童的双侧髋关节进行了超声检查和X线摄影。病理结果基于髋臼指数增加、髋臼外侧缘骨质缺损以及股骨近端的外侧和/或近端移位。每个髋关节被分类为正常、发育不良、半脱位或脱位。在312个髋关节中，超声和X线摄影对其中303个髋关节得出了相同的诊断结果。在正常关节、半脱位和脱位的情况下，一致性良好。然而，在15个X线摄影显示发育不良的髋关节中，有7个超声检查结果正常。这些患者未接受治疗，且他们全部实现了自发正常化或病情改善。超声和X线摄影仅测量了一个参数，即股骨头骨骺中心外侧边缘到珀金斯线的距离；相关性很高（r = 0.73）。当临床怀疑有先天性脱位时，我们建议将超声作为主要的成像技术。
