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. The front of the foot is bent inward at a sharp angle at the instep. The back of the foot and the ankles are normal.
Physical examination is sufficient to diagnose metatarsus adductus.
Exercises consist of gently straightening the foot and holding it straight for one minute. Parents are often asked to do this at each diaper change as a reminder to continue the exercise . Rigid metatarsus that has not resolved by 3 months should be referred to an orthopedic specialist. Call your health care provider if you are concerned about the appearance or flexibility of your infant's feet.
