In radial polydactyly, the Wassel’s classification is most commonly employed. This classification depends upon the bifurcation site of the thumb. In this paper the author discusses his experience in the treatment of duplicated thumb at various levels.

In duplicated thumbs, the supernumery digit (thumb) is excised in patients in whom one of the two thumbs is extremely hypoplastic. When both of the digits have an equal amount of tissue, some reconstructive surgical procedure is employed to centralize the thumb to improve the cosmesis and/or function. If thumb excision is done in such a case, the thumb may develop instability, axial deviation and may require secondary procedures for stabilization. The thumb may develop vascular compromise, though rarely, due to anomalous vascular supply. The author has employed the Bilhautcloquet procedure or its modification in the treatment of 12 cases of duplicated thumb.

This paper discusses the entity, the surgical technique and the results in 12 cases of duplicated thumb. The mean follow up is 3 years.
