The purpose of this study was to investigate whether the mode of delivery for fetuses in breech presentation in any way influenced the frequency of congenital hip dislocation. In 13,559 singleton births 583 fetuses were in breech position, and the cesarean section rate was 39.1%. Eighty-three infants were born with congenital hip dislocation, 11 of whom had been in breech position. Of these 11, cesarean section was required in 5 cases. There was no difference in frequency of congenital hip dislocation between fetuses in breech presentation delivered by cesarean section vs. by the vaginal route. The frequency of breech presentation in congenital hip dislocation was 13.3%. Including 7 external versions, the rate was 21.7%. Female to male ratio was 4:1. The frequency of congenital hip dislocations in infants born in vertex presentation was 5.5 per mille and for infants born in breech presentation it was 18.9 per mille.
本研究的目的是调查臀位胎儿的分娩方式是否会以任何方式影响先天性髋关节脱位的发生率。在13559例单胎分娩中，有583例胎儿为臀位，剖宫产率为39.1%。83例婴儿出生时患有先天性髋关节脱位，其中11例曾为臀位。在这11例中，有5例需要剖宫产。剖宫产与经阴道分娩的臀位胎儿先天性髋关节脱位发生率没有差异。先天性髋关节脱位中臀位的发生率为13.3%。包括7例胎位外倒转术，该发生率为21.7%。男女比例为4:1。头位出生婴儿的先天性髋关节脱位发生率为千分之5.5，臀位出生婴儿的发生率为千分之18.9。
