We report a rare case of a dual neuro-vascular variation, which was observed in the right extremity of male cadaver. About an inch inferior to the elbow joint, three branches arose from the median nerve. These were the anterior interosseous branch, a Martin-Gruber branch (MGB) and a muscular branch. The MGB coursed infero-medially to join with the ulnar nerve by running posterior to the ulnar artery. It was surprising to observe that the MGB passed between the ulnar artery and its venae comitantes. There was an acute angulation of the MGB here, suggesting entrapment at this site.
