Hypothenar hammer syndrome in a 22-year-old male patient: a case report and review of literature

Abstract

Hypothenar hammer syndrome is a rare condition with a peculiar presentation that aids in making a clinical diagnosis. We present a 22-year-old male patient who presented with critical hand ischemia secondary to a distal ulnar aneurysm with distal embolization. The patient was treated with an aneurysmectomy with cephalic vein interposition graft, which resulted in complete reversal of his hand ischemia. This case report outlines the clinical presentation of this rare condition, along with a recent review of the literature.
