deformity in which the foot is twisted out of normal position; called also talipes. The foot may have an abnormally high longitudinal arch (talipes cavus) or it may be in dorsiflexion (talipes calcaneus) or plantar flexion (talipes equinus), abducted, everted (talipes valgus), adducted, inverted (talipes varus), or various combinations of these (talipes calcaneovalgus, talipes calcaneovarus, talipes equinovalgus, or talipes equinovarus). There are several theories as to the cause of clubfoot. A familial tendency or arrested growth during fetal life may contribute to its development, or it may be caused by a defect in the ovum. It sometimes accompanies meningomyelocele as a result of paralysis. In mild clubfoot there are slight changes in the structure of the foot; more severe cases involve orthopedic deformities of both the foot and leg. Although clubfoot is usually congenital, an occasional case in an older child may be caused by injury or poliomyelitis.
also known as talipes equinovarus, clubfoot is a foot deformity that is detected at birth. It affects the bones, muscles, tendons, and blood vessels and can affect one or both feet. The foot is usually short and broad in appearance and the heel points downward while the front half of the foot, or forefoot, turns inward. The heel cord (Achilles tendon) is tight. The heel can appear narrow and the muscles in the calf are smaller compared to a normal lower leg.
