C5 and C6 Spinal Cord Injuries: Can They Cause Paralysis?

Yes, C5 and C6 spinal cord injuries can cause paralysis. The extent depends on whether the injury is complete or incomplete. A complete injury at this level typically results in quadriplegia (paralysis of all four limbs). An incomplete injury may cause partial weakness or loss of function in the arms, hands, and legs. Not every C5 or C6 injury results in total paralysis—some people retain significant arm and hand function.

Where Are C5 and C6 in the Spine?

C5 and C6 are cervical vertebrae in the middle-to-lower neck. The cervical spine contains seven vertebrae (C1 through C7). C5 and C6 sit roughly in the middle of this region. The spinal cord runs through the center of these bones, carrying signals between your brain and the rest of your body. When the spinal cord is damaged at the C5 or C6 level, those signals are disrupted, affecting the arms, hands, shoulders, and potentially the legs and trunk.

Cervical spinal nerves at C5 and C6 control signals to the shoulders, arms, and hands. The higher the injury in the cervical spine, the more of the body is typically affected. A C5 injury is higher than a C6 injury, so C5 injuries often result in greater loss of function.

What Are the Symptoms of C5 and C6 Nerve Damage?

Symptoms of a C5 or C6 spinal cord injury appear suddenly or develop over hours after the injury. Common signs include:

• Arm and hand weakness or paralysis on one or both sides
• Loss of sensation in the arms, hands, shoulders, or chest
• Difficulty gripping, pinching, or performing fine motor tasks
• Shoulder weakness or inability to lift the arms
• Leg weakness or paralysis in complete injuries
• Loss of bladder or bowel control in complete injuries
• Breathing difficulty in severe complete injuries

The severity of symptoms depends on whether the injury is complete (total damage to the spinal cord at that level) or incomplete (partial damage). Complete injuries cause total loss of function below the injury site. Incomplete injuries may preserve some sensation or movement, even if weakened.

Do C5 and C6 Injuries Affect Walking?

Complete C5 and C6 spinal cord injuries usually result in quadriplegia, meaning walking without assistance is not possible. Incomplete injuries may preserve some leg function, allowing walking with aids, braces, or assistance. The degree of leg involvement depends on how much of the spinal cord is damaged.

Recovery and rehabilitation can sometimes improve function over time, but this varies widely. Physical and occupational therapy help people maximize remaining function and learn adaptive techniques for daily tasks.

What Causes C5 and C6 Spinal Cord Injuries?

Car and truck crashes are among the leading causes of C5 and C6 spinal cord injuries. Other common causes include:

• Falls from height or onto the neck
• Diving accidents into shallow water
• Penetrating injuries such as gunshot or stab wounds
• Contact sports injuries
• Medical procedures or complications (rare)

High-impact collisions, rollovers, and sudden deceleration in crashes can fracture or dislocate the C5 or C6 vertebrae, damaging the spinal cord inside.

What Happens Immediately After a C5 or C6 Injury?

Immediate medical care is critical. Emergency responders stabilize your neck and spine to prevent further damage. In the hospital, doctors order imaging (CT or MRI scans) to assess the injury and determine whether surgery is needed. Many C5 and C6 injuries require surgery to stabilize the spine, remove bone fragments, or relieve pressure on the spinal cord.

After initial stabilization, rehabilitation begins in the hospital and continues in specialized spinal cord injury centers. Physical therapy helps prevent muscle atrophy and teaches techniques to work with remaining function. Occupational therapy focuses on self-care, communication, and adaptive equipment. Long-term care may include assistive devices, home modifications, ongoing medical appointments, and attendant care.

Complete vs. Incomplete Spinal Cord Injuries

A complete spinal cord injury means the spinal cord is fully severed or damaged across its entire width at that level. All signals below the injury site are blocked. A complete C5 or C6 injury typically results in quadriplegia with little or no voluntary movement or sensation below the injury.

An incomplete spinal cord injury means some nerve fibers remain intact. Signals may pass through partially, preserving some sensation or movement below the injury. Incomplete injuries often have better recovery potential than complete injuries, though outcomes vary widely.

Legal Rights After a C5 or C6 Spinal Cord Injury

If your C5 or C6 injury resulted from a car crash, truck accident, or another person’s negligence, you may have a legal claim. A spinal cord injury brings medical and financial costs that can begin in the hospital. These costs often extend far into the future.

A lawyer can investigate the crash, identify who was at fault, and discuss what options may be available based on your facts. Virginia generally allows two years from the date of injury to file a personal injury lawsuit (Va. Code § 8.01-243(A)); the clock runs from the date of injury, not the date of discovery, with narrow exceptions.

If the injury caused a death, a wrongful death claim may be possible. A Virginia wrongful death action is filed by the decedent’s personal representative within two years of the death (Va. Code §§ 8.01-50(C), 8.01-244(B)), on behalf of the family members the statute protects.

Virginia follows contributory negligence: if you are found even partly at fault, you may be barred from recovering, with limited exceptions (Contributory negligence bars recovery in Virginia). Talk to a lawyer about your facts.
