The hypothenar hammer syndrome is an uncommon lesion that is defined as digital artery insufficiency due to an ulnar artery aneurysm caused by repetitive trauma of the hand. Here, we present a case with a large thrombosed distal ulnar artery aneurysm that presented as a ulnar tunnel syndrome, with paresthesia in the ulnar fingers. He was treated by aneurysm resection and reversed vein graft reconstruction and made a full recovery. A review of the literature was done.
