Delayed ulnar nerve palsy secondary to ulnar artery pseudoaneurysm distal to Guyon's canal following penetrating trauma to the hand

P F Dobson et al. Ann R Coll Surg Engl. 2013 Jul.

Abstract

Compression of the ulnar nerve in Guyon's canal is an uncommon phenomenon. Reports of ulnar nerve palsy secondary to ulnar artery pseudoaneurysm at this anatomical location are very rare and equivalent pathology just distal to this site is unheard of. Here we present such a case, which featured a delayed onset of symptoms. This followed penetrating trauma to the hand. Our methods for diagnosis, operative planning and surgical treatment are included.
