Metatarsus Adductus (C-shaped Foot)


What is Metatarsus Adductus?

Commonly known as a c-shaped foot, it is a foot deformity in some infants when born. The feet can bend inwards from the middle of the feet to the toes.

It usually improves on its own without treatment, however if the child reaches age 6 - 9 months, and the condition has not improved, then special corrective shoes or casts are recommended.



The cause of metatarsus adductus is often postural. It occurs in approximately 1 out of 1,000 to 2,000 live births and effects girls and boys equally. Other causes may include:

  • Family history
  • Position of the baby in uterus (breech position)
  • Prone sleeping position

Babies born with Metatarsus Adductus may also be at increased risk of having an associated hip condition know as Developmental Dysplasia of the Hip (DDH)



Treatment would depend on the severity of the condition. Options include:

  • Stretching
  • Casting 
  • Bracing
