TAHERI, M. M. H. & AFSHAR, M. Connection between radial and ulnar nerves at humeral level and its clinical significance: Acadaveric case report. Int. J. Morphol., 33(4):1559-1562, 2015.SUMMARY: Variations of the terminal branches of the brachial plexus in the upper limb are abundant and frequently have beenreported. But connection between its radial and ulnar nerves at humeral level is very rare. During routine dissection of the ri ght arm of a75-year-old male cadaver in the Department of Anatomy of Birjand University of Medical Sciences (BUMS), in Iran, we observed aconnection between radial and ulnar nerves, and from the literature reviewed, we found only two cases that had been reported pr eviously,one of them was unilateral and the other bilateral. Awareness of such variations are very important for surgeons and diminish t he possiblecomplication of regional anesthesia and surgical procedures, hence, we decided to report it.KEY WORDS: Radial nerve; Brachial plexus; Ulnar nerve; Anatomical variation; Connection.
