Brachial Plexus Injury
Five nerves exit the spinal cord at the base of the neck to create the brachial plexus. These nerves work together to perform various tasks, including supplying energy to muscles and relaying sensory information from the hand to the brain. The brachial plexus is vulnerable to tension, strain, or overstretching damage. Damage to this prevents any signals from traveling from the spinal cord to the hand, wrist, elbow, and shoulder. A nerve may sustain a partial or complete tear when stretched more forcefully. However, an avulsion injury occurs when a nerve root is ripped from the spinal cord.
On the other hand, brachial neuritis is an uncommon, debilitating disease affecting the brachial plexus nerves. Pain in the shoulder and upper arm may come on suddenly and be severe with this condition. Weakness, muscle loss, and even loss of feeling can follow.
The most frequent source of injury in reported patients is a motorbike accident, although other things, including falls, car accidents, knives, and weapons, may also cause it. These injuries may rise due to rising survival rates from high-velocity motor vehicle incidents and increasing rates of involvement in high-energy sports. Cancer and radiation therapy are other potential causes of nerve damage and birth defects in infants.
