Abstract

Hypothenar hammer syndrome is a thrombosis of the ulnar artery in Guyon’s canal induced by repeated trauma. It is a rare disorder that can be diagnosed with an extensive medical history and physical examination, and confirmed by vascular studies. Management options include medical treatment and reconstructive surgery. The aim of this article is to provide a brief overview of this disorder and to discuss the case of a 45-year-old patient who developed paresthesias and signs of hypoperfusion of the fourth and fifth fingers following multiple injuries to the hypothenar eminence. The Allen test revealed the absence of vascularization in the ulnar artery, and thrombosis was verified by Doppler ultrasound and angiotomography. The thrombosed portion was excised, and Guyon’s canal was cleared. The evolution was satisfactory; no signs of ischemia were found, and paresthesias improved. Follow-up was performed for 1 year.
