title: Variations in the formation of the median nerve and its clinical correlation.
abstract: Variations in the formation of the median nerve are of interest to anatomists, radiologists, and surgeons. These variations may be vulnerable to damage in surgical operations, but their knowledge also helps in the interpretation of a nervous compression having unexplained clinical symptoms. We studied the variation  in the formation of the median nerve in 87 cadavers, i.e. 174 upper limbs  of formalin preserved cadavers at the department of Anatomy, Subharti medical  college. We observed an additional root taking part in the formation of the  median nerve in 26.4% of upper limbs, unusual low formation of the median  nerve in the arm in front of the brachial artery in 18.4% of upper limbs, and median nerve formation medial to the axillary artery in 10.3% of upper limbs. Knowledge of such anatomical variations is of interest to the anatomist and clinician alike. Surgeons who perform procedures involving neoplasm or trauma  repair need to be aware of these variations.
