To assess the association between gestational age versus corrected age at the time of hip ultrasound with findings for developmental dysplasia of the hip (DDH) in preterm breech infants.
A retrospective medical chart review was conducted to examine hip ultrasounds of 318 premature breech infants for findings associated with DDH.
Positive findings for DDH occurred in 3/135 (2%) of infants <32 weeks gestational age and 17/183 (9%) of infants 32 to <37 weeks gestational age (odds ratio: 0.22, 95% CI: 0.04 to 0.79, P<0.015). No infants born <32 weeks gestational age had abnormal findings for DDH upon follow-up ultrasound. Infants <40 weeks corrected age at the time of hip ultrasound were more likely to have DDH findings compared with infants ⩾44 weeks corrected age (odds ratio: 7.83, 95% CI: 2.20 to 29.65, P<0.001).
Current hip ultrasonography policies that include screening of premature breech infants may need to be revised.
评估早产臀位婴儿进行髋关节超声检查时的胎龄与矫正年龄与髋关节发育不良（DDH）检查结果之间的关联。
进行一项回顾性病历审查，以检查318例早产臀位婴儿的髋关节超声检查结果，寻找与DDH相关的表现。
胎龄小于32周的婴儿中，3/135（2%）出现DDH阳性结果；胎龄32至小于37周的婴儿中，17/183（9%）出现DDH阳性结果（优势比：0.22，95%置信区间：0.04至0.79，P<0.015）。胎龄小于32周的婴儿在后续超声检查中未出现DDH异常结果。髋关节超声检查时矫正年龄小于40周的婴儿比矫正年龄≥44周的婴儿更有可能出现DDH检查结果（优势比：7.83，95%置信区间：2.20至29.65，P<0.001）。
当前包括对早产臀位婴儿进行筛查的髋关节超声检查政策可能需要修订。
