Formation Variation of the medianus nerve: A Cadaveric Case Report

The median nerve, the longest branch of the brachial plexus, is formation in axillary fossa by a fusion of two nerves including the radix lateralis nervi mediani and radix medialis nervi mediani. A variant of that formation was observed during routine dissection at anatomy department of our faculty. It was found that the left median nerve was formed by three branches (two lateral and one medial). One of the roots originated from the fasciculus medialis; the other two roots originated from the fasciculus lateralis. This variation should be known and has clinical importance especially in surgical interventions, surgical interventions of traumatic cases and radiologic evaluations in order not to mislead the clinician
