Bilateral thenar hammer syndrome as a result of cumulative trauma: a case report.

Abstract

This report describes an unusual case of bilateral radial artery thrombosis associated with multiple weblike stenoses and pseudoaneurysms secondary to cumulative trauma in a manual laborer who used both hands for impacting at both the thenar and hypothenar aspects of the hand. In this case, thenar hammer syndrome was associated with acute ischemia of the long finger. The condition was treated surgically with arterial resection and reestablishment of blood flow to the hand. Noted improvement occurred with restoration of arterial competence.
