One hundred sixty-two neonates with sonographically diagnosed developmental dysplasia of the hip (200 hips) according to the method of Graf were treated with a Pavlik harness until sonographic maturation was reached. Eight patients (12 hips) treated with closed reduction and retention in a bilateral hip spica cast were included. When the children started to walk their acetabular indices were assessed and demonstrated low-grade dysplasia in 26% and high-grade dysplasia in 6% according to the criteria of Tönnis and Brunken. We discuss the current sonographic criteria defining treatment-induced normalization and the adequacy of the length of treatment. We conclude that despite normal values at the end of treatment dysplasia may develop, which necessitates further radiological monitoring of all hips initially rated at risk on sonography. When to end monitoring, however, remains to be determined.
根据格拉夫（Graf）方法经超声诊断为髋关节发育不良的162例新生儿（200个髋关节）采用帕夫利克吊带（Pavlik harness）治疗，直至超声检查显示成熟。纳入8例采用闭合复位并双侧髋人字石膏固定治疗的患儿（12个髋关节）。当患儿开始行走时，根据托尼斯（Tönnis）和布伦肯（Brunken）的标准评估其髋臼指数，结果显示26%为轻度发育不良，6%为重度发育不良。我们讨论了目前定义治疗诱导正常化的超声标准以及治疗时长的充足性。我们得出结论，尽管治疗结束时数值正常，但仍可能发生发育不良，这就需要对所有最初超声检查评定为有风险的髋关节进行进一步的放射学监测。然而，何时结束监测仍有待确定。
