Symptoms of arm nerve damage

Nerves are the most important part of our body because when our body nerves are damaged, it will affect our normal actions. The arm nerves are controlled by the brain, which enables them to perform various movements. However, nerves are prone to disease. For example, under special circumstances, if they are damaged, they will be unable to perform specific movements, affecting normal behavior. What are the symptoms of nerve damage in the arm?

Symptoms should be brachial plexus injury. The brachial plexus is composed of the anterior branches of the C5-C8 and T1 spinal nerves, which control movement and sensation of the upper limb and shoulder. When the brachial plexus or the peripheral nerves composed of its fibers are damaged, paralysis of the muscles innervated by the nerve and sensory disturbances in its distribution area or dysfunction of the entire upper limb and shoulder may occur. The main causes of injury include birth trauma, trauma, bone development abnormalities, lead and alcohol poisoning. There are two types of treatment: surgical and non-surgical. Acupuncture treatment has a good restorative effect on nerve damage. Traditional Chinese medicine belongs to the category of tendon injury.

Treat according to syndrome differentiation

1. Brachial plexus injury mainly occurs when fetal traction is performed during difficult labor, causing direct injury to the supraclavicular fossa and axilla of the neck. The main symptoms are motor and sensory disturbances in the distribution of nerve roots. Injury to the upper part of the brachial plexus is manifested by drooping of the entire upper limb, adduction of the upper arm, inability to abduct or externally rotate, adduction and extension of the forearm, inability to pronate, supinate or flex, and the movement of the hand and fingers can still be preserved; there is a narrow area of ​​sensory impairment on the outside of the scapula, upper arm and forearm. Injury to the lower brachial plexus is manifested by atrophy of the small muscles of the hand, which become claw-shaped, loss of sensation on the ulnar side of the hand and medial forearm, and sometimes Horner's syndrome.

2. Axillary nerve injury is most often damaged in shoulder fractures and dislocations. It manifests as inability to abduct the shoulder, atrophy of the deltoid muscle, and loss of skin sensation on the deltoid surface.

3. Damage to the long thoracic nerve is easily caused by carrying heavy objects on the shoulders. It manifests as paralysis of the serratus anterior muscle, forming a winged scapula.

4. Musculocutaneous nerve injury is often damaged in humeral fractures. It manifests as biceps atrophy, disappearance of biceps reflex, and a small area of ​​sensory loss on the outer side of the forearm.

5. Radial nerve injury: Fracture of the middle part of the humerus, improper sleeping posture, lead and alcohol poisoning can all cause damage to this nerve. Since the radial nerve mainly innervates the extensor muscles of the forearm, the typical symptom when it is injured is wrist drop.

6. A common cause of median nerve injury is improper intravenous injection in the antecubital area. It is manifested by loss of grip strength and forearm pronation function, a flat palm and a loss of most sensation in the fingers.

7. The ulnar nerve is most likely to be injured when the olecranon of the ulna is fractured, the medial epicondyle of the humerus is dysplastic, or when suffering from leprosy. Typical changes are loss of small muscle movements in the hands, affected fine finger movements, and the formation of claw hands. Sensory loss is primarily on the ulnar side of the dorsum of the hand.
