[Ulnar parametacarpal flap. Experience with 10 clinical cases].
The parametacarpal ulnar flap is raised from the dorsal and ulnar aspect of the hand. It is vascularized by the distal division of the dorsal branch of the ulnar artery. The skin flap is innervated by the dorsal sensory branch of the ulnar nerve helpfull for the reconstruction of skin loss of the palm. At the level of the metacarpo-phalangeal joint of the fifth finger, the medial division is connected by a constant anastomosis with the fifth ulnar collateral artery. This anatomic disposition held the flap to be raised in two manners: as direct flow useful to cover the defects of the palmar aspect of the hand, or as reverse flow covering the defects of the fourth and fifth fingers. In this paper, the authors present an anatomic reminder and the surgical procedure. They report ten clinical cases and precise the indications of this flap in hand reconstruction.
