metatarsus adductus
Pronunciation: met-ah-TAR-sus ad-DUK-tus
A common foot deformity in newborns where the front part of the foot turns inward, often resolving without treatment.
Full Definition
Metatarsus adductus is a common congenital foot deformity characterized by inward angulation of the forefoot while the hindfoot remains in normal position. The condition affects approximately 1-2 per 1,000 live births and is more common in firstborn children and those with intrauterine positioning constraints. The deformity is classified as flexible, partially flexible, or rigid based on the examiner's ability to correct the position manually. Most cases are flexible and resolve spontaneously with normal growth and development. Treatment options range from observation and stretching exercises for flexible deformities to serial casting or surgical correction in severe, rigid cases. Early recognition and appropriate classification are important for determining the need for intervention.
Usage
Usage note: Note distinction from clubfoot (talipes equinovarus). Some sources use 'metatarsus varus' synonymously.
