Transplantation of composite latissimus dorsi myocutaneous flap and vascularized fibula was performed primarily to repair the tibial defects in 12 cases and radial defects in 2 cases, both of which were associated with large-sized skin defects. The peroneal artery and vein of the fibula were anastomosed to the circumflex scapular artery and vein of the myocutaneous flap, the subscapular artery and vein, as the common vascular pedicle of the two transplants, are anastomosed to the nutrient vessels in the recipient site. Cross-bridge vascular anastomosis was used in 13 cases . All of tfe transplanted tissues survived, Follow-up revealed a good growthof the transplanted flaps, solid union between the transplanted fibulas and the host bones, and the good functional recovery of the repaired extremities. The operative indication and technique were introduced, ahd the merit of the repair ahd reliability of the cross-bridge procedure were discussed.
