Pediatric Metatarsus Adductus



Metatarsus adductus happens when a child is born with the front half of the foot turned inward.

Expanded overview

Metatarsus adductus is a common foot deformity found at birth (congenital) in which the front half of the foot turns inward.

Children with metatarsus adductus are at greater risk for developmental dysplasia of the hip. When this happens, the socket of the hip joint is too shallow and the top of the femur (thigh) bone may slip in and out of the socket.


Metatarsus adductus can be:

  • Flexible — The foot can be straightened by hand.
  • Nonflexible — the foot cannot be straightened by hand.


There is no known cause of metatarsus adductus; however, it is more common in first born children. About one in every 1,000 babies is born with metatarsus adductus.
