The three-square-flap method for reconstruction of minor syndactyly.

A three-square-flap procedure is described for surgical treatment of minor syndactyly. The average follow-up period in 58 cases (48 patients) was 2 years 4 months. In the three-square-flap method, the interdigital space is regarded as a cube and flaps are designed on each surface of the cube (dorsal side, interdigital surface, and volar side); the flap on the dorsal side forms the basal surface of the new interdigital portion. This technique is most suitable for reconstruction of minor three-dimensional contracture syndactyly. This method does not require skin grafting; the design is uncomplicated and easy to understand, and the operative procedure is simple.
