Abstract
Intermittent occlusion of the ulnar artery developed in a patient causing cramp in her right hand. Both flexion and extension of the wrist completely obstructed bloodflow in the ulnar artery, a level just proximal to the wrist. At operation, a tight hand of antebrachial fascia was found to the cause of this intermittent arterial occlusion. Surgical release of this fascial ban reduced complete relief of her symptoms.
