[Latissimus dorsi flap in reconstructive surgery of the lower limbs]

The free latissimus dorsi flap has been used to repair 10 complex losses of substance of the lower extremity. The results have shown the great reconstructive potentialities of the microvascular transfer of this muscle, considered by the authors the most versatile of the myocutaneous flaps. Among the advantages there are the extended surface, its thickness, its pedicle with adequate length and diameter as well as the absence of functional involvement, especially by preserving the upper branch of the thoracodorsal nerve. The indications, however, are limited due to a significant rate of complications which prevent its extended use.
