Polidactilia de um polegar trifalangeano é uma forma de polidactilia pré-axial dos dedos, caracterizada pela presença de um polegar trifalangeano geralmente opositor, que pode ou não estar duplicado. Sua forma pode variar (cunha a retangular) e pode estar desviada no plano radioulnar (clinodactilia). Os ligamentos, músculos, tendões e articulações comprometidos do polegar duplicado, desde a articulação interfalangeana distal até a articulação radiocarpal, podem ser hipoplásicos, malformados ou ausentes com vários graus de rigidez ou instabilidade. Duas formas foram caracterizadas: unilateral e bilateral. A doença é herdada de maneira autossômica dominante. | |||

Polydactyly of a triphalangeal thumb is a form of preaxial polydactyly of fingers, characterised by the presence of a usually opposable triphalangeal thumb which may or may not be duplicated. Its shape may vary (wedge to rectangular) and it can be deviated in the radio-ulnar plane (clinodactyly). The involved ligaments, muscles, tendons and joints of the duplicated thumb from distal interphalangeal joint to radiocarpal joint can be hypoplastic, malformed, or absent with varying degrees of stiffness or instability. Two forms have been characterised: unilateral and bilateral. The disease is inherited in an autosomal dominant manner. | |||

Polydactyly of a triphalangeal thumb is a form of preaxial polydactyly of fingers, characterised by the presence of a usually opposable triphalangeal thumb which may or may not be duplicated. Its shape may vary (wedge to rectangular) and it can be deviated in the radio-ulnar plane (clinodactyly). The involved ligaments, muscles, tendons and joints of the duplicated thumb from distal interphalangeal joint to radiocarpal joint can be hypoplastic, malformed, or absent with varying degrees of stiffness or instability. Two forms have been characterised: unilateral and bilateral. The disease is inherited in an autosomal dominant manner.
