Anatomical basis of dorsal forearm flap. Based on posterior interosseous vessels.

Injection studies on 35 upper limbs with neoprene latex were carried out and the limbs carefully dissected to observe the vascular contribution of the posterior interosseous branches of the dorsal forearm, the transverse anastomosis between anterior and posterior interosseous vessels and the calibre of the vessel. The findings indicated that a fascio-cutaneous flap based on septocutaneous branches of the posterior interosseous artery can be raised as a reversed forearm flap for resurfacing after skin loss in the hand.
