Concurrent variations of median and musculocutaneous nerves and their clinical correlation--a cadaveric study.
Variations of median nerve, musculocutaneous nerve and their communicating branches are of interest for anatomists and surgeons. These variations may be vulnerable to damage in surgical procedures. We examined median nerve and musculocutaneous nerve concurrently in 58 cadavers, i.e. 116 superior extremities, and found median nerve innervating muscle of the anterior compartment of arm in the absence of musculocutaneous nerve in 11.2% superior extremities, splitting of median nerve in the arm into median nerve proper and musculocutaneous nerve in 5.12% superior extremities, and communication between median and musculocutaneous nerves in 20.7% superior extremities. Knowledge of such anatomical variations is helpful for surgeons treating neoplasm or repairing trauma.
