Complex polydactyly is a congenital syndactyly that is not uncommon in clinical practice. The complexity and diversity of the clinical manifestations and the severity of the effects on hand and foot function and appearance are very different from simple syndactyly or polydactyly. CASE1: A child with a compound deformity of multiple syndactyly, a deformity of the 5th toe, an abducted 6th toe, and connected webbing. Complete removal of the 5th toe to prevent recurrence of the deformity. CASE2: A child with multiple syndactyly, 5th toe deformity, abducted 6th toe, and webbed toe, the webs were shallower than in case 1. The tendon was still to be repaired and no skin graft was placed. The 6th toe deformity was corrected, and the cast was fixed with a Kirschner pin, which was removed 2 weeks later. This photo shows the appearance of the child after removal of the cast and before removal of the keratoplasty pin, with superficial debridement of the wound. CASE3: The child had a multiple toe deformity with a severe inversion of the 5th toe. Excision of the extra toe, correction of the 5th toe, tendon and ligament repair, and fixation of the cast with a kyphotic pin. This picture shows the appearance of the child after the cast was removed 2 weeks after surgery and before the removal of the kyphosis pin. CASE4: At the age of 1 year, the child was treated with a postoperative syndactyly and the deformity recurred. A special flap design was used to separate the juxtaposed fingers without intraoperative skin grafting.
