ABSTRACT

ObjectiveTo introduce clinical experience of the modified lateral crural reverse island skin flap with two sets of blood supply system for aged ankle & foot soft tissue defect.MethodsOn the anatomy base that cutaneous artery branches of lateral crural reverse island skin flap and perforating branches of sural neurocutaneous vascular flap were originated from peroneal artery, we designed the modified lateral crural reverse island skin flap located in posterolateral cruris treated for aged ankle & foot soft tissue defect. The modified flap had two sets of blood supply system which were from lateral crural flap and sural neurocutaneous flap.ResultsAll 11 flaps survived. The skin grafting of donor sites healed well. Followed up 3-9 months, six cases were satisfactory. Five cases with extensor defect were regained by tendon transplantation after 3 months of the operations.Conclusion The modified lateral crural reverse island skin flap with two sets of blood supply system is a good method for aged ankle & foot soft tissue defect.
