Talipes Talipes calcaneovalgus SNOMEDCT_US:31668003 Pes calcaneovarus HP:0001884 Talipes calcaneovalgus is a flexible foot deformity (as opposed to a rigid congenital vertical talus foot deformity) that can either present as a positional or structural foot deformity depending on severity and/or causality. The axis of calcaneovalgus deformity is in the tibiotalar joint, where the foot is positioned in extreme hyperextension. On inspection, the foot has an "up and out" appearance, with the dorsal forefoot practically touching the anterior aspect of the ankle and lower leg. SNOMEDCT_US:205083002 UMLS:C0152237
