Brachymetatarsia is a rare malformation that causes one or more toes to be abnormally short. The condition is characterized by a metatarsal arch shortness of more than 5 mm. The condition is more common in females, and the incidence reported in the literature ranges from 0.02% to 0.05%. Brachymetatarsia appears to be the result of epiphyseal plate retardation or premature closure. The etiology may be congenital and idiopathic, posttraumatic, postinfection, iatrogenic, or secondary to a systemic disease such as cancer, sickle cell disease, pseudohyperparathyroidism, Turner's syndrome, Down's syndrome, Apert syndrome, athyroidism, or osteodystrophy.[2]
It most frequently involves the fourth metatarsal. If it involves the first metatarsal, the condition is known as Morton's syndrome. Treatment is via a number of differing surgical procedures.[3]
