Talipes equinovarus Clubbing of feet Clubfeet Clubfoot Foot, talipes equinovarus UMLS:C0009081 Clubfoot is a complex, multifactorial deformity with genetic and intrauterine factors. One popular theory postulates that a clubfoot is a result of intrauterine maldevelopment of the talus that leads to adduction and plantarflexion of the foot. On radiographic projection a clubfoot can be noted as parallel axes of talus and calcaneus. Fetal foot inversion refers to malposition of the foot originating during development involving inversion at the region of the metacarpals or more usually the subtalar joint and represents the prenatal sonographic equivalent of talipes equinovarus.
