Rotational Deformities of the Tibia and Foot in Preterm Infants: PDF OnlyKatz K. M.D.; Naor, N. M.D.; Merlob, P. M.D.; Wielunsky, E. M.D.Journal of Pediatric Orthopaedics: July-August 1990 Buy Abstract Summary: 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 ≤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. Address correspondence and reprint requests to Dr. K.
