title: Allen's test: a tool for diagnosing ulnar artery trauma.
abstract: Trauma to the ulnar artery was first reported by Von Rosen in 1934. In more recent years this condition has been termed ulnar-artery thrombosis, hypothenar hammer syndrome or post-traumatic digital ischemia. Trauma to the ulnar artery is caused by the repeated use of the hand as a hammer in order to apply force to an object. Any person who presents with a history of trauma to the hypothenar eminence of the hand should be screened for ulnar artery thrombosis. This screening can easily and quickly be performed by the nurse utilizing the Allen test. Early detection of vascular insufficiency coupled with cessation of chronic trauma may help the client avoid reconstructive vascular surgery.
