The congenital condition with which the baby was born is called polydactyly or polydactylism or hyperdactyly. This condition results in additional fingers and toes in humans and animals. There are three main types of the condition: ulnar or postaxial polydactyly or small finger duplication, which is the most common form of the condition; radial or preaxial polydactyly or thumb duplication, which occurs one in every 1,000 to 10,000 live births; central polydactyly, which is the rarest.
Polydactyly, also called hyperdactyly, occurs in several species of animals, including cats and humans.
