VERTICAL DOUBLE FLAP DESIGN FOR REPAIR OF WIDE DEFECTS OF THE LOWER-LIMB, USING COMBINED ASCENDING SCAPULAR AND LATISSIMUS-DORSI FLAPS

Two cases are presented in which a scapular osteocutaneous flap and a latissimus dorsi musculocutaneous flap were applied as combined flaps with a single pedicle, to repair massive soft-tissue defects resulting from tibial hemisection in the lower limb. In each case, the oval-shaped donor site was divided into two parts (an ascending scapular flap and a latissimus dorsi flap, respectively) to repair the resected area, using a vertically designed, combined flap from the dorsolateral region. Consequently, after flap elevation, the donor site could be closed primarily and functions of the affected limb could be completely reconstructed. For reconstruction of defects too large to be covered with a single flap, the vertical double flap design of a combined ascending scapular and latissimus dorsi flap is a good alternative. It has the merits of easy dissection, broad area skin coverage and it also provides a composite flap that contains a scapular bone graft. Moreover, it allows a simple microsurgical anastomosis, as well as direct closure of the donor site. In addition, when the recipient site is on the lower leg, flap elevation can be carried out simultaneously with surgery at the recipient site. This means that the operative time can be shortened.
