[Forearm flap with its various possibilities of application].

The authors describe the different possibilities of the forearm flap as a free and pedicle flap. The forearm flap is arterialized by the A. radialis, the venous outflow goes through the Venae comitantes of the A. radialis or the big veins of the forearm (V. cephalica and basilica). Sensation can be preserved through the three cutaneous forearm nerves. The advantage of the flap is based on the constant anatomy, the big vessels and nerves, the quality and quantity of the forearm skin as well as the relatively thin layer of subcutaneous fat.
