Calcaneovalgus deformity
HP:0001848
What it means
This is a postural deformity in which the foot is positioned up against the tibia. The heel (calcaneus) is positioned downward (that is, the ankle is flexed upward), and the heel is turned outward (valgus).
Calcaneovalgus deformity may be related to abnormal positioning of the foot in utero and can resolve spontaneously after birth.
