[The hypothenar hammer syndrome].
The hypothenar hammer syndrome (HHS) is a rare form of secondary Raynaud's phenomenon in workers who frequently use the ulnar side of the palm as a hammer. Clinically the patient with HHS shows neurologic symptoms such as paresthesia, numbness and pain and signs of vascular insufficiency such as coldness, pallor, discoloration and blanching of the affected ulnar sided fingers. The diagnosis is verified by angiography, showing thrombosis or aneurysm of the distal ulnar artery. We report on the treatment and outcome of 5 patients with HHS. All patients were painfree after treatment. But with the ongoing working habit of using the hand as a hammer there is always the risk of a recurrence. Therefore the job environment has to be changed considerably and the most effort should go into prevention and prophylaxis. If the change of the working habit is not possible, the job is clearly at stake.
