Schematic (left) and intraoperative (right) view of the proposed interface. The UN (arrow) is transferred to the LH of the biceps and provides both motor and sensory nerve fibers. The axons enter the muscle, efferent fibers reinnervate the muscle and a portion of afferent fibers extend into the overlying glabrous dermal skin graft (*), thus creating a bi-directional, biological interface.
