The authors report on 85 adduction-derotation osteotomies and 13 operations on the acetabulum performed in 56 children with cerebral palsy. Such causes as were observed of an increased tendency toward reabduction are described, taking age at operation into consideration. Other postoperative complications, including fragment dislocations and fractures of the shaft of the femur following disuse osteoporosis, are pointed out. The problem of the "anti-Chiari effect", resulting from the negative function of the hypsiloid cartilage, is discussed with regard to the formation of the "Chiari roof".
作者报告了对56例脑瘫患儿实施的85例内收-旋转截骨术和13例髋臼手术。描述了所观察到的再外展倾向增加的原因，并考虑了手术时的年龄。还指出了其他术后并发症，包括废用性骨质疏松后股骨碎片脱位和股骨干骨折。就“Chiari顶”的形成，讨论了由高位软骨的负向作用导致的“反Chiari效应”问题。
