There are two main clusters of clinically significant radial artery perforators. Increased knowledge of size, location, and cutaneous territory of the radial artery perforators can lead to expanded use of the radial artery forearmflap based on cutaneous perforators alone, without sacrificing the radial artery.

The main benefit of using this protocol in this selected group of patients is to shorten total morbidity time and to avoid exposure of the patient to two operations instead of one.
