An Unusual Third Root of the Median Nerve from the Musculocutaneous Nerve: A Case Report

Nerve variations in the brachial plexus, particularly the median nerve, are clinically significant due to their implications in surgeries and nerve compression syndromes. This case report details an anatomical variation observed during the routine dissection of a 72-year-old male cadaver. A third root of the median nerve originating from the musculocutaneous nerve was found in the right upper limb. This finding aligns with previous studies on brachial plexus variations and underscores their importance in surgical planning and nerve repair procedures. Knowledge of such anomalies is crucial for preventing iatrogenic injuries and improving outcomes in reconstructive surgeries.
