Abstract
We herein report the successful reconstruction of an extensive circular skin defect of the elbow region using a boomerang-shaped lateral-to-back muscle-sparing latissimus dorsi myocutanous flap utilizing multiple thoracodorsal artery perforators around the lateral border of the latissimus dorsi. The patient was a 74-year-old woman who presented with pleomorphic sarcoma in the left elbow region. The tumor was extensively resected and the skin defect was 13.5 × 12 cm. The boomerang-shaped lateral-to-back muscle-sparing-latissimus dorsi myocutanous flap was transferred as a free flap with the pedicle vessels anastomosed to the brachial artery and vein. The 2 wings of the boomerang were bent in a U shape to completely cover the skin defect. The donor site was closed primarily. This flap can be a versatile option for reconstructing extensive skin defects in various areas with little donor-site morbidity.
