Abstract Tissue with a blood supply derived from a single constant vascular pedicle may be raised as a flap and rotated within the reach of its blood supply to cover and reconstruct a variety of complex wounds. The latissimus dorsi muscle makes an ideal pedicled flap because of its long neurovascular pedicle, large size, ease of mobilization, and expendability. It can be rotated, with or without overlying skin, to cover soft-tissue defects involving the shoulder, arm, and elbow, or it can be transferred as an innervated muscle to improve shoulder abduction as well as elbow flexion and extension. The major clinical applications of the pedicled latissimus dorsi muscle flap for upper-extremity reconstruction include use as a bipolar transfer to improve elbow flexion after trauma or brachial plexus injury and as a nonfunctioning myocutaneous transfer for coverage of nerves, bones, and joints after soft-tissue loss due to trauma, tumors, infection, or irradiation.
