Metatarsus adductus - Overview
Metatarsus varus; Forefoot varus
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 baby's bottom pointed down in the womb (breech position)
- The mother had a condition called oligohydramnios, in which she did not produce enough amniotic fluid
There may also be a family history of the condition.
Metatarsus adductus is a fairly common problem. It is one of the reasons why people develop "in-toeing."
Newborns with metatarsus adductus often have a problem called developmental dysplasia of the hip (DDH), in which the thigh bone slips out of the hip socket.
