Polydactyly

Polydactyly is a fairly common, genetically induced deformity of the hands and feet found more often in blacks than in whites. Careful clinical and radiographic evaluation should be made prior to treatment because the complexity of the deformity ranges from a simple soft tissue appendage to a completely developed accessory ray. Treatment usually consists of surgical excision of the least functional, least developed digit. Hallux varus, angular deformities, and a splayed forefoot are common postoperative complications.
