Soft tissue coverage of lower extremity defects: pearls and pitfalls in the chronic wound population

Abstract

The incidence of chronic lower extremity (LE) wounds continues to increase. Lower limb amputations are associated with increased cardiovascular exertion, further decline in functional ability, and higher mortality rates. As such, there has been a shift towards limb salvage modalities. These include local debridement with advanced wound care, revascularization, bony reconstruction, and soft tissue reconstruction. Perioperative planning for soft tissue reconstruction requires careful consideration of several factors, including patient comorbidities, wound size and location, exposed underlying structures, and in the case of possible free flap, patency of donor and recipient vessels. This article reviews the perioperative factors that should be considered in preparation for successful soft tissue reconstruction of the LE.
