OverviewA spinal cord injury — damage to any part of the spinal cord or nerves at the end of the spinal canal (cauda equina) — often causes permanent changes in strength, sensation and other body functions below the site of the injury. Show
If you've recently injured your spinal cord, it might seem like every aspect of your life has been affected. You might feel the effects of your injury mentally, emotionally and socially. Many scientists are optimistic that advances in research will someday make repair of spinal cord injuries possible. Research studies are ongoing around the world. In the meantime, treatments and rehabilitation allow many people with spinal cord injuries to lead productive, independent lives. SymptomsYour ability to control your limbs after a spinal cord injury depends on two factors: where the injury occurred on your spinal cord and the severity of injury. The lowest part of your spinal cord that remains undamaged after an injury is referred to as the neurological level of your injury. The severity of the injury is often called "the completeness" and is classified as either of the following:
Additionally, paralysis from a spinal cord injury can be referred to as:
Your health care team will perform a series of tests to determine the neurological level and completeness of your injury. Spinal cord injuries can cause one or more of the following signs and symptoms:
Emergency signs and symptomsEmergency signs and symptoms of a spinal cord injury after an accident include:
When to see a doctorAnyone who has significant trauma to the head or neck needs immediate medical evaluation for a spinal injury. In fact, it's safest to assume that trauma victims have a spinal injury until proved otherwise because:
If you suspect that someone has a back or neck injury:

CausesSpinal cord injuries can result from damage to the vertebrae, ligaments or disks of the spinal column or to the spinal cord itself. A traumatic spinal cord injury can stem from a sudden, traumatic blow to your spine that fractures, dislocates, crushes or compresses one or more of your vertebrae. It can also result from a gunshot or knife wound that penetrates and cuts your spinal cord. Additional damage usually occurs over days or weeks because of bleeding, swelling, inflammation and fluid accumulation in and around your spinal cord. A nontraumatic spinal cord injury can be caused by arthritis, cancer, inflammation, infections or disk degeneration of the spine. Your brain and central nervous systemThe central nervous system comprises the brain and spinal cord. The spinal cord is made of soft tissue and surrounded by bones (vertebrae). It extends down from the base of your brain and contains nerve cells and groups of nerves called tracts, which go to different parts of your body. The lower end of your spinal cord stops a little above your waist in the region called the conus medullaris. Below this region is a group of nerve roots called the cauda equina. Tracts in your spinal cord carry messages between your brain and the rest of your body. Motor tracts carry signals from your brain to control muscle movement. Sensory tracts carry signals from body parts to your brain relating to heat, cold, pressure, pain and the position of your limbs. Damage to nerve fibersWhether the cause is traumatic or nontraumatic, the damage affects the nerve fibers passing through the injured area and can impair part of or all the muscles and nerves below the injury site. A chest (thoracic) or lower back (lumbar) injury can affect your torso, legs, bowel and bladder control, and sexual function. A neck (cervical) injury affects the same areas in addition to affecting movements of your arms and, possibly, your ability to breathe. Common causes of spinal cord injuriesThe most common causes of spinal cord injuries in the United States are:
Risk factorsAlthough a spinal cord injury is usually the result of an accident and can happen to anyone, certain factors can predispose you to being at higher risk of having a spinal cord injury, including:
ComplicationsAt first, changes in the way your body functions can be overwhelming. However, your rehabilitation team will help you develop tools to address the changes caused by the spinal cord injury, in addition to recommending equipment and resources to promote quality of life and independence. Areas often affected include:
PreventionFollowing this advice might reduce your risk of a spinal cord injury:
Oct. 02, 2021 What is the most common cervical spine injury?Cervical sprains and strains
Fractures and dislocations of the cervical spine account for half of all spinal column injuries that occur annually. Because of the cervical spine's mobility, it is the most vulnerable to injury during times of trauma.
What is the most common injury of spinal cord?According to the National Spinal Cord Injury Statistical Center (NSCISC), the two most common types of spinal cord injuries are incomplete tetraplegia and paraplegia, with incomplete spinal cord injuries accounting for more than 65% of all SCIs.
Why are most spinal cord injuries in the cervical?The cervical portion of the spine includes the top portion of the spinal cord, comprising seven vertebrae (C-1 to C-7) in the neck. Being closer to the brain and affecting a larger portion of the body, cervical spinal cord injuries are typically the most severe variety of spinal cord injury.
What is the most common cause of cervical fracture?A fracture, or break, in one of the cervical vertebrae is commonly called a broken neck. Cervical fractures usually result from high-energy trauma, such as automobile crashes or falls. In elderly people, ground-level falls, such as falling off a chair, can result in a cervical fracture. Athletes are also at risk.
