Definition of Metatarsus adductus

Metatarsus adductus is a foot deformity. The bones in the front half of the foot bend or turn in toward the body.

Causes, incidence, and risk factors

Metatarsus adductus is thought to be caused by the infant’s position inside the womb. Risks may include:


The front of the foot is bent or angled in toward the middle of the foot. The back of the foot and the ankles are normal. About half of children with metatarsus adductus have the problem in both feet.

Signs and tests

Physical examination is all that is needed to diagnose metatarsus adductus.


Treatment depends on how rigid the foot is when the doctor tries to straighten it.

Expectations (prognosis)

The outcome is almost always excellent. Nearly all patients eventually have a normal looking and working foot.
