ABSTRACT

Background: Median nerve is the nerve of the flexor compartment of forearm. Variations in the formation of median nerve is common. Knowledge of such variations is important for the evaluation of nerve injuries in upper limb region.

Materials & methods: The study was done on 36 formalin fixed cadavers (72 upper limbs). The pattern of formation of median nerve in axilla was observed after performing meticulous dissection.

Observations: Out of total 72 specimens, 67 upper limbs (93.06%) showed formation of median nerve by the fusion of two roots while in the remaining five specimens (6.94%), median nerve was formed by three roots. Out of those five specimens, all of them showed median nerve formation by two medial and one lateral root. Out of the total 72 specimens, three specimens showed communication between median and musculocutaneous nerve in the arm region and two specimens showed absence of musculocutaneous nerve.

Conclusion: This study has described the normal way of formation of median nerve as well as the variations in its roots of formation.

Key words: Median nerve, Lateral & medial root, Roots of formation.
