We all know that there is a row of vertebrae in the back of the human body, including the head and neck, down to the sacrococcygeal area, a total of 33, medically known as the “spine”. In addition to supporting the body, balancing and completing various flexion and extension, rotation and other movements, it also has a very important function, which is the “spinal canal” composed of the upper and lower links of each vertebra, which plays a role in protecting the spinal nerves. When the spine is traumatized, resulting in vertebral fractures, broken bones or other foreign objects (such as bullets, bomb fragments, etc.) can directly or indirectly damage the spinal nerves (e.g., destruction of spinal blood vessels, resulting in spinal cord necrosis due to impaired blood flow). In addition, hematoma caused by bleeding in the spinal canal can also cause spinal cord injury by compressing the spinal cord. In general, the causes of spinal cord injury are divided into two categories: traumatic spinal cord injury and non-traumatic spinal cord injury (mainly spinal cord diseases, such as myelitis, spinal cord hemorrhage, spinal cord tumors, etc.).
