Polydactyly of the foot. Literature review and case presentations.
Polydactyly is a fairly common congenital condition of the foot and is characterized literally by supernumerary toes (digit or metatarsal). The frequency of polydactyly varies widely among populations. 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). The duplication may appear at the distal and middle phalanges or at the whole digit and metatarsal. The complexity of the deformity ranges from a simple soft-tissue problem to a completely developed accessory ray. Careful clinical and radiographic evaluation should be made prior to treatment to achieve good functional and cosmetic results. Most cases are treated during childhood before walking age. Adult cases are more rare, and surgical management of the deformity is still debated. Nevertheless, surgery can be performed at any age as in our series with good results.
