[Clinical analysis of the double-wing flap for treatment of toe syndactyly]

Objective: To explore the clinical effect of double-wing flap for the treatment of toe syndactyly. Methods: Retrospective analysis of 47 patients (60 syndactyly toes) who underwent double-wing flap to reconstruct toe web space in orthopedics department of the Third Affiliated Hospital of Zhengzhou University from February 2010 to October 2017.There were 21 males and 26 females, with an average age of 18.9 months (range: 10-48 months). All patients were treated with zigzag incisions to separate the toe syndactylys without skin grafts.The condition of wound healing and appearance of toes were observed. Results: The average follow-up time was 62.3 months (range: 6 to 80 months). There were no complications such as hematoma, infection, flap necrosis and no flexion contracture and obvious scar hyperplasia in all the 47 cases, 4 of the 60 webs developed web creep.All webs had good appearance with 45 degrees inclination from the dorsal to the metatarsal side and had good flexion and abduction function. Conclusions: The double-wing flap is a simple and safe operation for toe syndactyly which has a good clinical effect.
