summary Brachymetatarsia is a rare congenital condition caused by premature epiphyseal closure of the metatarsals that presents with shortening of one or more metatarsals. Diagnosis is made clinically with hypoplasia and shortening of most commonly the 4th metatarsal. Treatment is observation with shoe modifications for mild cases. Surgical metatarsal lengthening may be indicated in patients with persistent pain with shoe wearing.
