[Polydactyly].

The authors reports the experience of the plastic surgery unit in the Kassab's Institute of Orthopedics in Tunis. This series consists of 44 cases of polydactyly dominated by duplication of the little finger and the thumb. A slight male predominance was observed and the mean age at surgery was 8 years. Two types of polydactyly were observed: simple, such as rudimentary digits, complex, with associated bone malformation or syndactyly. In ulnar polydactyly, associated duplication of the toes in frequently noted. The most frequent surgical approach was amputation of the more dystrophic finger with reconstruction and correction of the other congenital malformation observed. Some cases of digital redistribution were also performed. A review of the literature is presented together with an objective analyse of esthetic and functional results.
