Bifid thumb is a rare manifestation of polydactyly. The trait is autosomal dominant, but the expressivity is highly variable. It must be distinguished from apical dystrophy, a rare form of brachydactyly. Severe surgical procedures have been suggested for both functional and cosmetic reasons. Two families affected are described.
