Cervical Spinal Cord Injuries

The Cervical Spine

The cervical spine is located at the very top of the spinal column. The seven vertebral levels within this region, which are classified as C1-C7 from the top down, form the human neck. There is an additional cervical-level injury known as a C8 injury which relates to damage to the spinal cord root that exits the spinal column between vertebrae C7 and T1.

The spinal cord running through the cervical region of the spine is identified by the level of the vertebra in which it’s contained. Cervical spinal cord injuries are the most severe of all spinal cord injuries and may affect one or both sides of the body.

The higher up in the spine that the injury occurs, the more severe the potential outcome. Some cervical spinal cord injuries are severe enough to result in death. Injuries to C1 and C2 are very rare and most injuries to the cervical spinal column occur near the C4 / C5 levels. While no two spinal cord injuries are the same, early treatment is critical to the long-term prognosis of any injury to the cervical spinal column.

Cervical Spinal Cord Injury Levels

High-Cervical Nerves (C1-C4)

The C1 and C2 vertebrae from the top of the spine (neck) at the base of the skull. These bones are named atlas and axis respectively and support the pivot motion of the neck. Injuries to the spinal cord at the C1 & C2 levels are rare, extremely severe, and most often fatal. Atlas and axis are followed by C3 and C4 to form the high cervical vertebrae. If not fatal, complete damage to the spinal cord or nerves corresponding to any of the high-cervical vertebral levels most often results in full paralysis or quadriplegia. A survivor may not be able to breathe on their own and will likely require 24-hour care for the rest of their life.

Low-Cervical Nerves (C5-C8)

An individual with an injury to the cervical spinal cord at the C5 level or below has a greater chance of retaining some motor and sensory function than a patient who experiences an injury to the C1-C4 levels. Though damage to the spinal cord at any portion of the neck has the potential to result in full paralysis of each of the four limbs, survivors of C5-C8 injuries may be able to breathe on their own and speak normally.

Common Cervical Injury Symptoms

Patients with cervical spinal cord injuries will likely experience to some degree:

• Inability to breathe on one’s own without assistance (C1-C4)
• An impaired ability or inability to speak (C1-C4)
• Numbness, tingling, or loss of feeling below the level of the injury
• Paralysis in the legs, torso, and arms
• Inability to control bladder and bowel function
• Inability to groom or dress oneself

Treatment & Recovery

The unfortunate truth of spinal cord injuries is that there is no way to reverse damage to the spinal cord at any level. With cervical spinal cord injuries being the most severe of all spinal cord injuries, patients will have a long road to rehabilitation ahead of them.

Early treatment may include:

• Stabilizing and securing the neck to prevent further damage.
• Regulation of breathing and respiratory function.
• Prevention of complications including blood clots and stool or urine retention.

Long-term treatment and rehabilitation may include:

• Surgery to reduce pressure on the spinal cord.
• Steroid injections and pain regimens to reduce any discomfort and inflammation from the injury.
• Physical therapy to aid in regaining function of the affected parts of the body and to maintain the function in areas which were not affected by the injury.
• Stem cell injections are a new tool to aid in the recovery of the spinal cord. The use of stem cells has not been widely adopted, however, promising clinical data has been reported.

Mental Health

A patient with a cervical spinal cord injury will need a lot of assistance in dealing with the injury and what it means for their future. Mental health is of the utmost importance to a patient with a cervical spinal cord injury as mental health directly relates to physical health. These patients will have a range of emotional changes along with the physical changes; so keeping up with mental health is a must. Seeking out a therapist who deals with paralyzed patients may be a huge part of recovery.
