Spinal Cord Injury

Spinal cord injury (SCI) occurs when a traumatic event results in damage to cells within the spinal cord or cuts the nerve tracts that relay signals up and down the spinal cord.


The most common types of SCI include:

  • Contusion. This is bruising of the spinal cord.

  • Compression. This is caused by pressure on the spinal cord.

Other types of injuries include:

  • Lacerations. This is severing or tearing of some nerve fibers, such as damage caused by a gun shot wound.

  • Central cord syndrome. This is specific damage to the corticospinal tracts of the cervical region of the spinal cord.


Severe SCI often causes paralysis (loss of control over voluntary movement and muscles of the body) and loss of sensation and reflex function below the point of injury, including:

  • Autonomic activity such as breathing.

  • Other body functions such as bowel and bladder control.

Other symptoms may develop over time:

  • Pain.

  • Sensitivity to stimuli.

  • Muscle spasms.

  • Sexual dysfunction.

SCI patients are also prone to develop secondary medical problems, such as:

  • Bladder infections.

  • Lung infections.

  • Bedsores.


Advances in emergency care and rehabilitation allow many SCI patients to survive. Methods for reducing the injury and restoring function are still limited. Immediate treatment for acute SCI includes:

  • Techniques to relieve cord compression.

  • Prompt (within 8 hours of the injury) drug therapy with corticosteroids to minimize cell damage.

  • Stabilization of the vertebrae of the spine to prevent further injury.


The types of disability associated with SCI vary greatly depending on:

  • The severity of the injury.

  • The segment of the spinal cord at which the injury occurs.

  • Which nerve fibers are damaged.

Most people with SCI regain some functions between a week and 6 months after injury. The likelihood of spontaneous recovery diminishes after 6 months. Rehabilitation strategies can minimize long-term disability.


  • You have difficulty breathing or leg swelling.

  • You have a fever.

  • You feel nauseous, vomit, or have abdominal pain.

  • You feel lightheaded or faint.

  • You develop chest pain, an abnormal heartbeat (palpitations), or a fast heart rate.

  • You develop bad smelling urine, bedsores, or significant redness on your skin.
