Syndactyly is a common congenital hand anomaly resulting from incomplete separation of the digital rays during embryonic development. Traditional multistage repairs and skin-graft-based techniques may lead to donor-site morbidity, graft contraction, and aesthetic mismatch. We report the case of a 22-year-old man with multiple syndactyly involving the middle, ring, and little fingers of the left hand, treated with a single-stage graftless reconstruction using dorsal hexagonal local flaps. This approach enabled complete digital separation, preservation of finger length, and restoration of independent motion. At three months, the patient demonstrated preserved hand function, with a normal range of motion, maintained grip strength, and minimal scarring. This report highlights the applicability of a standardized graftless dorsal hexagonal flap for multiple-digit syndactyly, even in adults, who are traditionally considered less ideal candidates for single-stage repair.
