The median nerve is a crucial structure in the upper extremity, providing motor and sensory innervation to various muscles and skin regions of the forearm and hand. However, variations in the number and course of its fibers are frequently observed in clinical and anatomical studies. These variations, often due to developmental or congenital factors, can significantly impact clinical practices, including diagnosis, surgery, and nerve conduction studies. This article reviews the anatomical variations in the median nerve, focusing on variations in the number and course of its fibers, their potential causes, and the implications of these variations for clinical practice, particularly in nerve injuries, surgical procedures, and diagnostic assessments.
