The case of a man exposed during 25 years to vibration while maneuvering a heavy earth moving tractor is reported. The first clinical manifestation of hand-arm vibration syndrome was a bilateral Raynaud's phenomenon followed five years later by digital necrosis. The arteriography revealed a proximal and bilateral ulnar artery occlusion. Bilateral median nerve conduction abnormalities were also present. Vibration exposure level was much higher than the threshold level proposed by the European Commission. Laboratory were all negative. The purpose of this report is to show that vibration can be responsible for proximal occlusion of a medium sized artery and severe neurovascular abnormalities which must be distinguished from the usual vasospastic Raynaud's phenomenon and the classical hypothenar hammer syndrome. An early and correct diagnosis is crucial because continued repetitive trauma can result in irreversible ischemic injury and loss of digits.
