Metatarsus adductus Causes and Risks:
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.
Prevention:
There is no known prevention.
Symptoms:
- 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.
Signs and Tests:
Physical examination is sufficient to diagnose metatarsus
adductus.
Treatment:
Most cases (80%) resolve spontaneously. 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.
Prognosis:
Expect a full recovery.
Complications:
Congenital dislocation of the hip may be associated with a small number of infants with metatarsus
adductus.
Call Your Healthcare Provider:
Call your health care provider if you are concerned about the appearance or flexibility of your infant's feet.
