10 Essential Facts About What Is a Brachial Plexus Injury Today

A brachial plexus injury is a condition that affects the network of nerves responsible for controlling movement and sensation in the shoulder, arm, elbow, wrist, and hand. Understanding what is a brachial plexus injury is important because early diagnosis and proper treatment can improve recovery and reduce the risk of long-term disability. Many people experience these injuries after accidents, sports injuries, or difficult childbirth. Patients in Thrissur and other regions are increasingly seeking information about this condition because prompt medical attention often leads to better outcomes.

The brachial plexus is a complex group of nerves that begins in the neck and extends through the shoulder into the arm. When these nerves are stretched, compressed, torn, or completely detached from the spinal cord, normal communication between the brain and arm is disrupted. This may result in weakness, numbness, pain, or even complete paralysis of the affected limb.

Whether the injury is mild or severe, understanding the causes, symptoms, diagnosis, treatment, and rehabilitation process helps patients make informed healthcare decisions.

Understanding the Brachial Plexus

The brachial plexus is made up of five major nerve roots originating from the spinal cord:

These nerves combine and divide into multiple branches that control:

Shoulder movement
Arm strength
Elbow motion
Wrist movement
Hand function
Sensation throughout the upper limb

When any part of this nerve network is injured, different functions of the arm may be affected depending on the location and severity of the damage.

What Is a Brachial Plexus Injury

A brachial plexus injury occurs when the nerves of the brachial plexus become damaged due to excessive stretching, pressure, tearing, or avulsion (complete separation from the spinal cord).

The injury may affect one nerve or multiple nerves, leading to varying degrees of weakness and loss of sensation. Some people recover naturally, while others require surgery and long-term rehabilitation.

The severity depends on:

Type of injury
Number of nerves involved
Age of the patient
Time before treatment
Overall health

Common Causes of a Brachial Plexus Injury

Several situations can damage the brachial plexus nerves.

Road Traffic Accidents

Motorcycle and car accidents are among the leading causes. High-speed impacts may stretch or tear the nerves.

Sports Injuries

Contact sports such as:

Football
Wrestling
Rugby
Martial arts

can cause sudden stretching of the neck and shoulder.

Falls

Falling heavily on the shoulder or arm may injure the nerve network.

Birth Injuries

During difficult deliveries, excessive pulling on a baby’s shoulder may cause neonatal brachial plexus injury.

Penetrating Injuries

Knife wounds or gunshot injuries may directly damage the nerves.

Tumors

Growths near the neck or shoulder can compress the nerves over time.

Radiation Therapy

Rarely, previous radiation treatment may result in nerve damage.

Types of Brachial Plexus Injury

Different injuries require different treatment approaches.

Neuropraxia

The mildest form.

Characteristics include:

Temporary stretching
No nerve rupture
Usually heals naturally

Neuroma

Scar tissue forms around the injured nerve.

This can interfere with nerve signals and reduce movement.

Rupture

The nerve tears but remains attached to the spinal cord.

These injuries often require surgery.

Avulsion

The most severe injury.

The nerve root is completely pulled away from the spinal cord.

Recovery without surgery is usually impossible.

Symptoms of a Brachial Plexus Injury

Symptoms depend on the severity and location of nerve damage.

Common symptoms include:

Sudden severe pain
Burning sensation
Electric shock feeling
Shoulder weakness
