Metatarsus adductus is a foot deformity characterized by a sharp, inward angle of the front half of the foot. It is thought to occur as a result of the infant's position inside the uterus where the feet are bent inward at the instep. Most cases resolve spontaneously and the majority of the remainder can be corrected with simple exercises.
