Metatarsus adductus and medial tibial torsion are common in term infants. Our study shows that metatarsus adductus is rare, whereas medial tibial torsion does not occur in preterm infants with gestational ages of less than or equal to 30 weeks. These preterm infants have lateral rotation of the legs, external tibial rotation, and everted or normal feet at birth. This posture may explain the rarity of metatarsus adductus and medial tibial torsion in preterm infants.
内收型足和胫骨内旋在足月儿中很常见。我们的研究表明，内收型足很少见，而胎龄小于或等于30周的早产儿不会出现胫骨内旋。这些早产儿出生时腿部有外旋、胫骨外旋，足部外翻或正常。这种姿势可能解释了早产儿内收型足和胫骨内旋少见的原因。
