Abstract
Some patients with distal phalangeal polydactyly of the thumb have severe hypoplastic pulps that are difficult to make sufficiently large with either the fillet flap method or a symmetrical combination, the Bilhaut-Cloquet method. We have devised a new method to reconstruct the largest possible pulp by resecting only a minimum amount of soft dorsal skin tissue with one nail and not resecting any of the palmar skin of the thumbs. By contrast, other procedures require some resectioning of soft tissue of both the dorsal and the palmar skin. We have treated 13 cases with distal phalangeal polydactyly of the thumb since 1988 in this way. All the thumbs were successfully reconstructed with a sufficiently large pulp. The only problem was slight instability of the skin of the pulp after the operation, but this condition gradually improved during a five-year follow up. We think that this method facilitates the reconstruction of a sufficiently large pulp when both bifid pulps are hypoplastic.
