metatarsus adductus
Pronunciation: met-uh-TAR-sus ad-DUK-tus
A common foot deformity in infants where the forefoot is angled inward toward the midline.
Full Definition
Metatarsus adductus is a congenital foot deformity characterized by inward angulation of the metatarsals and forefoot while the hindfoot remains in normal position. It is the most common foot deformity in newborns and may be positional (flexible) or structural (rigid). Radiographic assessment involves measuring the metatarsus adductus angle on AP foot radiographs, though imaging is often not required for diagnosis. The condition must be distinguished from more severe deformities like clubfoot (talipes equinovarus) which involves both forefoot and hindfoot abnormalities.
Usage
Usage note: Use 'adductus' not 'adducted'; distinguish from the more severe clubfoot deformity.
