Magnetic resonance image findings in congenital talipes equinovarus.

Magnetic resonance imaging (MRI) was used to image the feet of 10 infants with congenital talipes equinovarus. Images in an intermediate density and T2 sequence are most useful. In the transverse plane, the primary deformity appears to be localized to a medical deviation of the talar neck and head, with an accompanying internal rotation of the calcaneus relative to the talar body. The posterior calcaneus is laterally deviated by this rotation. In the sagittal plane, the deformity appears to lie in a parallelism in the subtalar relationship.
