Application of dorsal double-wing flap for reconstruction of the web space in the fifth and fourth toe polysyndactyly / 中华整形外科杂志

ABSTRACT

Objective@#To explore the application of dorsal double-wing flap for reconstruction of the web space in the fifth and fourth toe polysyndactyly.@*Methods@#99 patients (112 feet) with polysyndactyly of the fifth toe fused with the fourth toe were treated, 75 of which were incomplete and 37 were complete fusion of the fourth and fifth toes. The fifth toes showed various degrees of fibular deviation and minor deformities. Excision of polydactyly and then with the use of wedge osteotomy correction deviation. Using 77 traditional and 35 modified dorsal double-wing flap for reconstruction of the web space, and close the lateral sides of toes with flaps from polydactyly. The distal soft tissue of polydactylies were used lengthening the reconstructed fifth toes.@*Results@#Polydactyly excision and syndactyly releasing in same procedure and lateral sides of the toes were all closed with flaps without skin grafts. Patients were followed up average 27 months after operation, the constructed web space showed good appearance, with slightly deeper or normal location. The fibular deviation were complete correction, and minor deformities were improved.@*Conclusions@#The dorsal double-wing flap is used for reconstruction of the web space in the fifth and fourth toes polysyndactyly without skin grafts. Reconstruction of the web depth, combined with lengthen distal end of the fifth could improve the toe appearance. Compared with traditional dorsal double-wing flap reconstruction of the web space, the modified flaps have better appearance in palmar of foot.
