Bilateral polydactyly of the adult foot: case report

Abstract

The polydactyly is a quite common congenital condition characterized by the presence of supernumerary toes. It can affect the hands and feet. However, there are few cases of bilateral foot polydactyly described in the literature. Distinct ethnic groups are affected and the incidence varies in different geographic regions. The disease may be an isolated condition or part of a congenital syndrome. It is usually classified into three groups: medial ray (preaxial), central ray (central) and lateral ray (postaxial). The disease can affect only the soft tissues or produce a completely developed metatarsal bone and toe. A careful clinical and radiographic evaluation should be made before treatment, in order to achieve good functional and cosmetic results. Most of cases are identified and treated in childhood, preferably in the preschool age, just before walking age. This fact may justify the case report in adults in the literature been rarer. Surgical treatment in adults is still debated, although the technique to be employed is relatively simple. It should be individualized for each case and take in concern the variety of presentation. However, the surgery can be performed at any age, usually with good results
