Pedal polydactyly: an overview with case report.

Polydactyly is a fairly common congenital condition of the foot, and is characterized by supernumerary digits and/or metatarsals. It may be an isolated condition or part of a congenital syndrome. Polydactyly is generally classified into three major groups: medial ray (preaxial), central ray, and lateral ray (postaxial). A review of polydactyly and an unusual case report of central ray involvement and its surgical correction are presented.
