Preferred Answer: 1
The lateral arm flap is a highly dependable free flap donor site of moderate size on the posterolateral aspect of the distal upper arm. The area is supplied by the posterior radial collateral artery, a direct continuation of the profunda brachii. The flap area is supplied by a direct cutaneous nerve. It can be raised on its own, with underlying tendon, with bone, or with fascia only.
