[Surgical cover of dorsolumbar radionecrosis. Apropos of 6 cases].

Thoracolumbar radionecrosis may be difficult to cover. We often use muscular or myocutaneus flaps available in this location, mainly the latissimus dorsi flap. It can be used as a pedicle, free, or especially a "reversed" flap with lumbar pedicles. However in our experience and in the literature this reversed flap is difficult to use because of the morbidity of the flap, transposed without its main pedicle. The authors consider the current methods of cover by flaps in six cases and in the literature. Surgical possibilities are now more numerous. First, a latissimus dorsi muscular flap autonomized by vascular delay, half-free flap, or a flap with the lengthening of its pedicle is possible. Second, we can also use an intercostal island flap for the back and a gluteal thigh flap in the lumbar region.
