What is Brachial Plexus?

The brachial plexus is a complex network of nerves that transmits signals from the spinal cord to the shoulder, arm, and hand, governing the movements of the hands, arms, and wrists. Injuries to the brachial plexus occur when these nerves are damaged or torn from the spinal cord. Factors such as shoulder trauma, tumors, and inflammation can impact the brachial plexus. The most severe injuries to the brachial plexus are often the result of automobile accidents.

Symptoms of Brachial Plexus Injuries

Damage to the upper nerves of the brachial plexus typically occurs when the shoulder is forcefully pulled down while the neck stretches away from it. Conversely, injury to the lower nerves happens when the arm is forcibly raised above the head. These injuries can arise from various situations:

• Sports
• Congenital issues
• Trauma
• Tumors

Side effects of Brachial Plexus Injuries

The symptoms of the injuries depend upon their severity, and the common symptoms are:

• Limp or paralyzed arm.
• No feeling or sensation in the arm or hand.
• Not being able to control or move your arm, hand or wrist.

Diagnosis of Brachial Plexus

The doctor evaluates your arm and hand to assess sensations and movements, which aids in diagnosing brachial plexus injuries. Common diagnostic tests used include:

• Magnetic Resonance Imaging (MRI).
• Computed Tomography (CT scan).
• Electromyogram.
• X-ray.

Treatment of Brachial Plexus

Brachial plexus injuries may require surgical intervention to mend the damaged nerves. Physical therapy is crucial for regaining movement and sensation in the arms and hands. Not all injuries necessitate treatment; some may heal on their own.

It's crucial to note that brachial plexus injuries often recover successfully when they are not severe. Individuals with minor or initial symptoms of brachial plexus injuries have a 90-100% likelihood of regaining normal function in the arm and hand.
