Review of Current Concepts in Metatarsus Adductus

Abstract

Metatarsus adductus (MA), the most common congenital foot deformity, involves adduction of the forefoot at the tarsometatarsal joint, with normal hindfoot alignment. Early diagnosis is important because treatment is more successful if initiated before age 9 months. Treatment of MA depends on deformity severity, in which mild to moderate deformity can be treated conservatively. Current standard of care for severe or rigid deformity involves referral by primary care physicians to specialists for management by casting and splinting. Recently, several orthoses have demonstrated equal effectiveness to casting and may allow for primary care physicians to treat MA without the need for referral. In this review article, we provide an overview of MA and discuss diagnosis and treatment. We also discuss novel devices and suggest how they may affect the future management of severe and rigid MA.
