The regions of the distal lower limb, including the 1/3 lower leg and foot areas are very prone to loss of soft tissue for trauma and ulcerations. The anterior position of the tibia, with its coverage slightly thick and vulnerable, besides the large amount of tendons, which can not remain exposed, requiring skin coverage quickly and simultaneously complex. The situation with respect to the direction of blood flow, lack of muscle bellies for flaps and skin flaps for inelastic randomized viable complicates this situation. In the past, with intermediate transfer flaps were used, as the leg cross, are still with major drawbacks: they rely on more than one occasion, generate a lot of discomfort to the patient and are not always effective. Microsurgery has become an option that helps a lot to cover injuries this point, however, depends on the team with training and specialized equipment. Donor areas are larger, can cause functional impairment and use on major vascular trunks. The fasciocutaneous flaps of reverse flow can contribute to the coverage of small and medium lesions in this location, with minor aesthetic damage and functional and less time for surgery. It constitutes effective surgical option for its ease, safety and versatility. In this study we demonstrate supramalleolous flap of reverse flow used in 4 cases, with applications in different situations, with satisfactory results easy and reproduction.
