Polymetatarsia is a rare congenital malformation which is characterized by the presence of 6 or more metatarsal bones in the same foot. It is most commonly seen alongside polydactyly, [1] and it often appears between the fourth and fifth metatarsals or beside the fifth metatarsal.
Few cases of polymetatarsia not associated with polydactyly have been reported. [2]
