Free-Style Free Perforator Flaps in Lower Extremity Reconstruction.

Improved knowledge of vascular anatomy has enabled surgeons to preoperatively identify perforators and design free-style flaps based on that perforator. Options for choosing the optimal donor site tissues are increased with the free-style technique. This reduces donor site morbidity while providing the same reconstructive success as traditional free skin flaps. The free-style technique allows the surgeon to successfully complete reconstruction when aberrant anatomy is encountered. With the necessary skills in perforator flap dissection and supermicrosurgery, the armamentarium of the reconstructive microsurgeon has been expanded with the introduction of free-style perforator free flaps.
