A variation of the brachial plexus and Radial nerve: A case report

Abstract

Background and Objective: Some of the brachial plexus and radial nerve variations have been reported. In many cases, variations could be important in clinical aspect. As anatomical situation of brachial plexus and radial nerve has an important role in explaining of their injuries and the neurological signs of those, paying attention to major variations of this nerve plexus seems necessary. Case: This report is a rare variation in order to posterior cord of brachial plexus is double and radial nerve originates in lower than of subscapular artery where two posterior cords conjoined together. Conclusion: As a result of posterior cord and radial nerve injuries in situations such as Saturday night syndrome and improper use of a cruch pressing on the nerve in the axillary fossa are related to their anatomical position, any changes in this situation can be make new expectancy in the etiology of injury and its neurological signs.
