Abstract

The hypothenar hammer syndrome (HHS) is a rare entity of secondary Raynaud’s phenomenon. The blunt hypothenar trauma causes a lesion of the vessel wall with a consecutive thrombosis or aneurysm of the ulnar artery at the Guyon’s canal. Different risk factors are discussed such as nicotine abuse, or a muscle anomaly in the Guyon’s canal. To date, there are five case reports published about muscle anomalies and HHS. We present a case of a 51-year-old shipbuilder with a unilateral HHS on his right dominant hand with a bilateral muscle anomaly. We successfully treated the patient by resection of the aneurysm without a resection of the atypical muscle.
