title: An unusual case of preaxial polydactyly of the hand (triplication of the thumbs).
abstract: Preaxial polydactyly is the most common duplication pattern in white and Asian populations (1). It is a congenital anomaly with a wide range of manifestations. Current classification do not have the capacity to classify all different types of radial polydactyly. We describe here a very rare and unusual case of bilateral preaxial polydactyly (triplication) in a woman and report the operations results. We have not found similar case in the literature. Our case is unique and did not fit into the classification systems described for thumb polydactyly.
