A section of tissue (usually skin) separated from underlying structures but still attached at its distal end by a PEDICLE through which it receives its blood supply. The free end may then be sutured into a new position to cover a defect caused by trauma or excision of diseased tissue. A free flap involves detachment of a section of tissue, often including bone and muscle, to a distant site where the artery and vein supplying it are anastomosed to adjacent vessels and the tissue is sutured into place. (See RECONSTRUCTIVE (PLASTIC) SURGERY.)
