[Hypothenar hammer syndrome]. / Le syndrome du marteau.

The hypothenar hammer syndrome is an uncommon but underestimated lesion of the cubital artery caused by repetitive trauma at the level of the hamate bone. It characteristically occurs in patients with a history of manual work as metal workers, carpenters and motor mechanics. We present a case of a patient who developed this syndrome following intensive use of a dig. Clinical finding, diagnosis and treatment are discussed.
