The 2017 figures below from the National Spinal Cord Injury Statistical Center (NSCISC) help paint a clearer picture of traumatic spinal cord injury (SCI)—who it affects, what causes it, and how much it costs.
It is important to note that spinal cord injury is categorized as 2 types: traumatic and non-traumatic. The facts in this article provide information specific to traumatic SCI. You may read more about non-traumatic SCI in our Spinal Cord Injury Center.
What Causes Traumatic Spinal Cord Injury?
Below are the top 5 causes of traumatic SCI:
The Spectrum of Severity for Traumatic Spinal Cord Injury
The severity of SCI depends on where the spinal cord is damaged, and if the injury is complete or incomplete.
SCI damage may cause paraplegia or tetraplegia. Paraplegia is paralysis (the inability to move) of both legs. Tetraplegia, also known as quadriplegia, means paralysis of both arms and both legs.
Tetraplegia occurs at the top of your spine—in the cervical spine, or neck. Your doctor may refer to your injury as “high” tetraplegia, meaning the damage is at the top of your neck (C1-C4). If your damage is called “low” tetraplegia, it occurred lower down on your cervical spine (C5-C7).
Below are the most common results of traumatic SCI:
Snapshot of Hospital Stays and Lifetime Costs
Traumatic SCI is a very costly disorder. The NSCISC published the following lifetime costs related to spinal cord injury, which don’t include indirect costs (such as lost wages or productivity).
People who experience a traumatic spinal cord injury have lower life expectancies than people who do not have an SCI. For example, a 40-year-old at the time of injury who has low tetraplegia is expected to live another 26 years after the first year of injury. If that person did not have SCI, his or her life expectancy would be another 41 years.
SCI life expectancies vary by age at the time of injury and severity of injury. During the first year after the injury, mortality rates are highest—they decrease after the one-year anniversary of the injury.
The top causes of death for patients surviving SCI are pneumonia and septicemia (blood poisoning). Other common causes of death for people with traumatic SCI are endocrine, metabolic, and/or nutritional diseases; nervous system problems; musculoskeletal disorders; and mental health disorders.
Researchers are continuing to study and refine innovative treatments to help people who experience spinal cord injury live longer, healthier lives. You can learn more about the current SCI research landscape in Spinal Cord Injury Clinical Trials and Therapies.
