Following anterior dislocation of the shoul-der, a pt develops weakness of flexion at elbow and lack of sensation over the lateral aspect forearm; nerve injured is:
B i.e. Musculocutaneous nerve Flexion of the elbow is caused by biceps brachii (musculo cutaneous nerve), brachialis ( muscolo cutaneous nerve) and branchioradialis (radial nerve)Q. So the nerve injured may be either musculocutaneus or radial. So lets see the cutaneous nerve supply of these nerves.
Radial nerve
Musculocutaneous nerve
Axillary nerve
Ulnar nerve
