title: Current options for treatment of hypothenar hammer syndrome.
abstract: Hypothenar hammer syndrome is a rare vascular condition resulting from injury to the ulnar artery at the level of Guyon canal. The ulnar artery at the wrist is the most common site of arterial aneurysms of the upper extremity and is particularly prone to injury. Signs and symptoms include a palpable mass, distal digital embolization to long, ring, or small fingers, pain, cyanosis, pallor, coolness, and recurrent episodes of vasospasm. Modalities for diagnosis, evaluation, and surgical planning include duplex study, contrast arteriography, and computerized tomographic angiography (CTA). Management includes medical, nonoperative, or operative treatments. Appropriate treatment options are reviewed.
