Manifested as twin thumb or radial and ulnar hyperdactylia of the thumb, duplication of the thumb falls into the category of deformity of hyperdactylia and is a relatively common kind of congenital hand deformity. It is classified as twin deformity or polydactylism. The twin thumb suffers dysplasia to varying extents in most cases.
