Connection between radial and ulnar nerves at high humeral level

Brachial plexus variations are not rare. Also variations in its terminal branches in the arm or forearm are frequently reported. During routine dissection of a 75-year-old male cadaver, we observed a connection between ulnar and radial nerves at high humeral level. We considered it as a rare variation. It is very important to know such variations to minimize the possible complications of regional anesthesia and surgery.
