Spinal column injury is trauma that causes fracture of the bone or instability of the ligaments in the spine; this can coexist with or cause injury to the spinal cord, but each injury can occur without the other. [23] Abnormalities might show up on magnetic resonance imaging (MRI), but the term was coined before MRI was in common use. [24]

The most common form of myelopathy in humans, cervical spondylotic myelopathy (CSM), [2] [3] also called degenerative cervical myelopathy, [4] results from narrowing of the spinal canal (spinal stenosis) ultimately causing compression of the spinal cord. [5] When due to trauma, myelopathy is known as (acute) spinal cord injury.

Once the spinal injury has occurred, one of two things may happen. Firstly, hemorrhaging within the spinal cord may cause compression, which damages the spinal cord even further. Another consequence of myelomalacia is improper circulation of blood to the area damaged, resulting in further damage to the spinal cord. [citation needed]
A bruise, also known as a contusion, is a type of hematoma of tissue, [3] the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration.
Tethering may also develop after spinal cord injury. Scar tissue can block the flow of fluids around the spinal cord. Fluid pressure may cause cysts to form in the spinal cord, a condition called syringomyelia. This can lead to additional loss of movement or feeling, or the onset of pain or autonomic nervous system symptoms. [5]
[10] An estimated 50 percent of spinal injuries are attributed to motor vehicle accidents. [10] Although the majority of vertebral fractures go undiagnosed, the annual cost related to treatment of vertebral fractures is estimated to be $1 billion in the U.S. [13] Symptomatic disc herniations are most common between ages 30–50 years.
