AIM
There is uncertainty about the risk of developmental dysplasia of the hip (DDH) in breech preterm infants and therefore uncertainty about the benefits of using ultrasound screening in this population. The aim of this study was to determine if preterm infants born in the breech position are at risk of DDH.
METHODS
A retrospective audit of preterm and term infants born in the breech position was performed to determine the incidence of DDH. Group 1 included breech preterm infants (<37 weeks gestational age) born between 2004 and 2008. Group 2 included breech term infants (≥37 weeks gestational age) born between 2005 and 2007. Infants were screened with clinical examination and ultrasound of the hip and were classified into two outcome groups: positive or negative for DDH.
RESULTS
Three out of 129 (2.3%) preterm infants screened had DDH. For term infants, 3 out of 163 (1.8%) infants screened had DDH. The odds ratio for DDH in breech preterm infants compared with breech term infants was 1.27 (95% confidence interval 0.25 to 6.40).
CONCLUSION
Preterm infants born in the breech position appear to have a similar incidence of DDH to term infants and thus require similar screening guidelines.
目的
臀位早产儿发生发育性髋关节发育不良（DDH）的风险存在不确定性，因此对于在该人群中使用超声筛查的益处也存在不确定性。本研究的目的是确定臀位出生的早产儿是否有患DDH的风险。
方法
对臀位出生的早产儿和足月儿进行回顾性审计，以确定DDH的发病率。第1组包括2004年至2008年出生的臀位早产儿（胎龄<37周）。第2组包括2005年至2007年出生的臀位足月儿（胎龄≥37周）。对婴儿进行临床检查和髋关节超声筛查，并分为两个结果组：DDH阳性或阴性。
结果
在129例接受筛查的早产儿中，有3例（2.3%）患有DDH。对于足月儿，在163例接受筛查的婴儿中，有3例（1.8%）患有DDH。臀位早产儿与臀位足月儿患DDH的比值比为1.27（95%置信区间0.25至6.40）。
结论
臀位出生的早产儿患DDH的发病率似乎与足月儿相似，因此需要类似的筛查指南。
