Hypothenar hammer syndrome and repair of ulnar artery aneurysm in a patient without history of trauma

BMJ Case Rep. 2021 May 20;14(5):e240729. doi: 10.1136/bcr-2020-240729.


The patient is a 50-year-old male with a history of tobacco use presented for evaluation of pulsatile right-hand mass. The patient was employed as a barber but had no known history of trauma or injury. He was diagnosed with hypothenar hammer syndrome and underwent excision of ulnar artery aneurysm with reconstruction of ulnar artery with interposition saphenous vein graft. The presented case describes an uncommon presentation of hypothenar hammer syndrome in a patient without history of repetitive blunt trauma or injury and discusses the diagnosis, pathophysiology and treatment options for symptomatic ulnar artery aneurysm.
