Metatarsus adductus

Alternative names:

forefoot varus; metatarsus varus

Definition:

A foot deformity characterized by a sharp inward angle of the front half of the foot.

Causes, incidence, and risk factors:

Metatarsus adductus is thought to occur as a result of the infant's position inside the uterus where the feet are bent inward at the instep. Metatarsus adductus is a flexible deformity and the foot can be straightened with little effort. The appearance may be of great concern to the parent but poses little risk for the infant. Nine out of ten cases resolve voluntarily and the majority of the remainder can be corrected with simple exercises.
