35 hips in 31 infants diagnosed as unstable were treated with a Pavlik harness and followed by weekly clinical and monthly ultrasound evaluation to determine eventual stability. 26 hips became stable within 3 months, and 9 dislocations required reduction with hip spica placement; 1 of these subsequently required open reduction. Of the 7 infants with 9 hips that failed, 2 children had a late onset of treatment, 2 children had problems with brace fit or family acceptance, and 3 other children had no problem with use of the orthosis. Internal rotation of a degree not possible with the Pavlik harness was required to reduce 4 of these 9 hips. The Pavlik harness is ineffective in some patients because of the need for internal rotation.
31名被诊断为髋关节不稳定的婴儿共35个髋关节接受了 Pavlik 吊带治疗,并每周进行临床评估,每月进行超声检查以确定最终的稳定性。26个髋关节在3个月内恢复稳定,9个髋关节脱位需要通过髋人字石膏固定进行复位;其中1个随后需要切开复位。在9个髋关节治疗失败的7名婴儿中,2名儿童治疗开始较晚,2名儿童存在支具佩戴问题或家庭接受度问题,另外3名儿童在使用矫形器方面没有问题。这9个髋关节中的4个需要进行 Pavlik 吊带无法实现的内旋才能复位。由于需要内旋,Pavlik 吊带在某些患者中无效。
