Reconstruction of soft-tissue injury associated with lower extremity fracture.

Soft-tissue loss associated with lower extremity fracture poses a substantial reconstructive challenge. Following stabilization of life-threatening conditions and bony disruptions, the reconstructive team must address the soft-tissue envelope of the limb. The wound is managed with débridement followed by coverage. Coverage options range from basic to complex and include delayed primary closure, healing by secondary intention, skin grafting, local flap coverage, and distant tissue transfer. The choice of soft-tissue coverage method is based on its ability to provide an environment conducive to fracture healing. Understanding the merits and disadvantages of each reconstructive option helps to avoid undertreatment or overtreatment.
