Living With a Spinal Cord Injury - What Happens

Often a spinal cord injury (SCI) is caused by a blow to the spine camera.gif, resulting in broken or dislocated bones of the spine (vertebrae.) The vertebrae bruise or tear the spinal cord camera.gif, damaging nerve cells.

When the nerve cells are damaged, messages cannot travel back and forth between the brain and the rest of the body. This causes a complete or partial loss of movement (paralysis) and feeling.

Sometimes the spinal cord is damaged by infection, bleeding into the space around the spinal cord, spinal stenosis, or a birth defect, such as spina bifida.

At the hospital

A person with a potential SCI is taken to an emergency department and then to an intensive care unit. The first priority is stabilizing blood pressure and lung function, as well as the spine, to prevent further damage. When a spinal cord injury is caused by a serious accident, treatment for other injuries is often needed.

The following tests may be done right away to help find out the extent of the injury. They may also be done routinely throughout and after you leave rehabilitation (rehab).

A few days after the injury, your doctor will ask you questions. Also, he or she will test not only the strength of key muscles but also your response to light touch and pinpricks all over your body.

Classifying a spinal cord injury

An SCI can be classified based on how much feeling and movement you have or where the damage occurred. When a nerve in the spinal cord is injured, the nerve location and number are often used to describe how much damage there is.

The vertebrae and spinal nerves are organized into segments camera.gif, starting at the top of the spinal cord. Within each segment they are numbered.

People with SCIs often use a segment of the spine to talk about their functional level. (Your functional level is how much of your body you can move and feel.) For example, you might describe yourself as a "C7."

The nerves around a vertebra control specific parts of the body. Paralysis occurs in the areas of the body that are controlled by the nerves camera.gif associated with the damaged vertebrae and the nerves below the damaged vertebrae. The higher the injury on the spinal cord, the more paralysis there is.

  • Damage to the spinal nerves in the neck can cause paralysis of the chest, arms, and legs (tetraplegia, also known as quadriplegia).
  • Damage lower down on the spine (thoracic, lumbar, or sacral segments) can cause paralysis of the legs and lower body (paraplegia).
  • Breathing is only affected by injuries high on the spinal cord.
  • Bowel and bladder control can be affected no matter where the spinal cord is injured.
