Unilateral Communication Between the Musculocutaneous and Median Nerves: A Rare Anatomical Variant Explored Through Cadaveric Dissection

Abstract

This study presents a rare anatomical variant of unilateral communication between the musculocutaneous and median nerves, discovered during cadaveric dissection. The variant was found in the right arm of a male cadaver, with no similar connection observed in the left arm. The communicating branch arose from the musculocutaneous nerve, passed through the coracobrachialis muscle, and joined the median nerve in the middle of the arm. This variant has significant implications for surgical interventions in the arm, diagnostic nerve conduction studies, and the interpretation of unexplained sensory and motor loss. The study emphasizes the importance of being aware of such variations in clinical practice.
