Metatarsus varus; Forefoot varusDefinition Return to top
Metatarsus adductus is a foot deformity characterized by an inward bending of the front half of the foot.Causes, incidence, and risk factors Return to top
Metatarsus adductus is thought to occur as a result of the infant's position inside the uterus. It can occur when the feet are bent inward, toward the midline, at the instep.
This is a relatively common disease affecting about one out of every 1,000 to 2,000 live births. Risk factors may include a condition called oligohydramnios where the mother does not produce enough amniotic fluid in the uterus.
Symptoms Return to top
Signs and tests Return to top
Physical examination is sufficient to diagnose metatarsus adductus.Treatment Return to top
Treatment depends on the severity of the deformity. Most children with metatarsus adductus can correct the deformity with normal use of their feet as they develop. These cases do not require any treatment.
For children who cannot do this, but who have an affected foot that can be easily manipulated to normal positioning, stretching exercises are all that is needed.
Rarely, this disease causes a rigid deformity that cannot be corrected with simple manipulation. In these cases, casting and even surgery may be required. Other diagnoses may need to be considered in these children. A pediatric orthopaedic surgeon should be involved in treating more severe deformities.
Expectations (prognosis) Return to top
Prognosis is excellent with nearly all patients attaining a normal appearing, fully functional foot.Complications Return to top
Developmental dislocation of the hip may be associated with a small number of infants with metatarsus adductus.Calling your health care provider Return to top
