Variations in the formation of the median nerve and its clinical correlation
Folia Morphol 2012;71(1):28-30.
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.
