A three-square-flap procedure is described for surgical treatment of m
inor syndactyly. The average follow-up period in 58 cases (48 patients
) was 2 years 4 months. In the three-square-flap method, the interdigi
tal 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 interdigita
l portion. This technique is most suitable for reconstruction of minor
three-dimensional contracture syndactyly. This method does not requir
e skin grafting; the design is uncomplicated and easy to understand, a
nd the operative procedure is simple.
