A Postaxial Polydactyly with a Partial Duplication of the Fifth Metatarsal Without a Supernumerary Digit Is Excision of the Duplicated Metatarsal Necessary?

초록

Postaxial polydactyly of the foot is one of the most common congenital malformations. Only a few cases of postaxial polydactyly with a partial duplication of the fifth metatarsal without a supernumerary digit have been reported, and both metatarsal heads were united to form a common joint with the proximal phalanx in all of those cases. We present a rare case of postaxial polydactyly with a partial duplication of the fifth metatarsal characterized by dual metatarsal heads and an extra proximal phalanx bud, without a supernumerary digit.
