Abstract

We present an unusual case of polydactyly of the thumb. The patient, despite having a fully developed nail bed, had a duplication at the metacarpophalangeal level consisting of a single bony phalanx. The Wassel classification of polydactyly, which is the most commonly cited classification scheme, does not include this particular anomaly. In addition, there has been no reference to this type of polydactyly in the literature.
