Combination of the Cross-Bridge Flap with Free Latissimus Dorsi and Fibular Flap to Repair the Composite Tissue Defect of Lower Leg

Introduction: The surgical technique of the combination of the cross-bridge flap with free latissimus dorsi and fibular flap to repair the composite defects of lower leg was introduced and its clinical value was discussed.

Methodology and Material: From May 2008 to October 2010, 5 cases of composite defects with soft tissue and tibia in lower leg was treated with the combination of the cross-bridge flap with free latissimus dorsi and fibula flap. The vascular anastomosed with the contralateral side, in which the subscapular vessel was anastomosed the posterior tibial artery and vein, the distal branch to anterior serratus muscle was anastomosed to the peroneal vessel of the free fibular flap. External fixator was used to immobilize the two legs. All the cases were followed up for 13-32 months, the average time was 21 months.

Results: All the composite flaps survived. X-ray showed callus bone growth in 3-6 months.

Conclusions: The bridging vascularized fibular-latissimus dorsi flap resolves the lack of donor vessels, is an effective technique to repair the composite defects of lower limb.
