Free tissue transfer is the autologous transplantation of composite tissue and its arterial and venous blood supply to a distant site. Free tissue transfers, also called free flaps, may include skin, fascia, muscle, or bone. Free flaps were once considered highly complex procedures; now they are frequently used as the reconstructive option of choice. While several variables must be considered when one plans a free tissue transfer, the most important consideration is the size and location of the defect created by the tumor resection. Free tissue transfer is a multistep procedure, including preparation of the recipient site, harvesting of the flap, and transfer and revascularization of the flap. For upper extremity reconstruction, the gracilis muscle flap has been particularly useful, as has the lateral arm fasciocutaneous flap. Semin. Surg. Oncol. 19:246-254, 2000.
