What happens if the musculocutaneous nerve is damaged?

Damage to this nerve can result in problems with the tissues in innervates, including: Loss of sensation in the skin on the front side of the forearm. Weakened flexion at the shoulder and elbow. Weakened rotation of the arm.

How do you test for musculocutaneous nerve?

Nerve conduction studies, electromyography and MRI scan should confirm a lower motor neurone and sensory nerve lesion and are useful in differentiating musculocutaneous nerve lesions from cervical spine nerve root impingement.

In what situation is the musculocutaneous nerve most likely damaged?

It may become injured by:

• Brachial Plexus damage.
• Compression injury eg weight lifting or sports involving lots of forarm flexing and supination.
• Dislocation of the shoulder.
• Shoulder surgery.
• Entrapment of the nerve at the elbow.

What is Musculocutaneous neuropathy?

Isolated injury to the musculocutaneous nerve is a rare occurrence. Associated signs and symptoms of an isolated musculocutaneous neuropathy may include weakness in elbow flexion or shoulder flexion, atrophy of the biceps brachii, and pain or paresthesia at the lateral forearm.

What muscles does musculocutaneous nerve pass through?

The musculocutaneous nerve innervates the three muscles of the anterior compartment of the arm: the coracobrachialis, biceps brachii, and brachialis. It is also responsible for cutaneous innervation of the lateral forearm.

What is the largest and longest nerve of the body?

Where is the musculocutaneous nerve located in the arm?

Introduction. The Musculocutaneous nerve is a large branch of the Brachial Plexus that supplies the flexors of the arm and sensation to the lateral forearm.

What are the symptoms of nerve entrapment at the elbow?

People describe symptoms as ranging from stiffness and tingling to dull pain and burning. Full extension and pronation of the arm increases the pain, while supination may reduce and eliminate the pain. If the condition continues to worsen, the pain and sensation changes will eventually extend from the elbow down to the wrist.
