Lower extremity reconstruction is challenging for a variety of reasons. New techniques for soft tissue coverage continue to evolve. While free flaps are always an option, free flaps require significant microsurgical expertise, a proficient staff, advanced equipment, and a patient with a somewhat healthy baseline. However, as microsurgery has evolved, so has the identification of new anatomy and new techniques - namely, perforator based pedicled flaps. These flaps have expanded options for lower extremity reconstruction, and continue to advance the field of microsurgery. The purpose of this article is to review the evolution of perforator based pedicled flaps in the lower extremity, review the anatomy, and offer examples of design and indications.
