The '''white hand sign''' is a [[Medicine:Medical sign|medical sign]] observed as a visible whitening of skin on the hand when the subject elevates the hands above the shoulder girdle with fingers pointing to the ceiling and palms facing forward. It results from this change in position causing a compression of the subclavian artery and temporary loss of circulation, as often occurs in patients with [[Medicine:Thoracic outlet syndrome|thoracic outlet syndrome]], a complex [[Medicine:Syndrome|syndrome]] involving the compression of various [[Biology:Nerve|nerve]]s and [[Biology:Blood vessel|blood vessel]]s between the axilla (armpit) and the base of the neck.
