[Traumatic aneurysm of the hand--a rare complication of a stab injury].

This is a case report of a 22-year-old male who suffered a stab injury to his right hand. Sixteen days after primary wound closure, he complained of pain from a pulsating mass in his right palm, with numbness along the ulnar side of the middle finger. At operation, a false aneurysm was found and resected, after ligation of the common digital artery proximal and distal to the aneurysm.
