This study was undertaken to determine the incidence of prenatally, sonographically diagnosed clubfoot; the incidence of associated anomalies; and the correlation with postnatal findings. Cases of prenatally diagnosed clubfeet were abstracted from a prospectively entered ultrasound database. Scans were reviewed for the presence of associated anomalies. Available neonatal charts were reviewed for correlation with prenatal findings. The incidence of prenatally diagnosed clubfoot was 0.43%. This was isolated in 33% of the cases and associated with other anomalies in 67%. All cases with associated anomalies were identified prenatally. There was a 40% false-positive rate for isolated clubfoot, all diagnosed in the third trimester of pregnancy. Prenatally diagnosed clubfoot was seen in 0.43% of this high-risk population. The correct identification of associated anomalies facilitates prenatal counseling, but limitations of prenatal ultrasound must be remembered. This information should be helpful to orthopaedic surgeons involved in the counseling of these patients.
本研究旨在确定产前超声诊断马蹄内翻足的发病率、相关畸形的发病率以及与产后检查结果的相关性。产前诊断为马蹄内翻足的病例摘自一个前瞻性录入的超声数据库。对扫描结果进行复查以确定是否存在相关畸形。查阅现有的新生儿病历以核对与产前检查结果的相关性。产前诊断马蹄内翻足的发病率为0.43%。其中33%为孤立性病例，67%与其他畸形相关。所有合并其他畸形的病例均在产前被识别。孤立性马蹄内翻足的假阳性率为40%，均在妊娠晚期被诊断。在这一高危人群中，产前诊断马蹄内翻足的发生率为0.43%。正确识别相关畸形有助于产前咨询，但必须牢记产前超声检查的局限性。这些信息对参与这些患者咨询工作的骨科医生应有所帮助。
