Brachial plexus injury following blunt trauma; an anatomical variation in electrodiagnostic findings

Abstract

Damage to the brachial plexus branches is one of themost important events during traumatic events, whichmay
cause various disabilities. Electrodiagnostic testing is the preferred method to evaluate the extent of damage to
the brachial plexus following trauma. The case presented in this paper, is a 26-year-old man who had near
normal function of pronator teres and flexor carpi radialis muscles on electrodiagnostic testing following a right
upper limb severe blunt injury at the level of his arm. After surgical investigation, we found a rare variation
in the proximal part of the median nerve. In this case, branches to the pronator teres muscle and flexor carpi
radialis had emerged from the proximal section of themedian nerve in the armregion. This new variation holds
important clinical implications especially in trauma patients presenting with weakness in forearmflexion.
