The various segments of the spinal cord mainly include the cervical, thoracic and lumbar nerves, and the common manifestations of their injuries include sensory disorders, motor disorders and dysfunctions of the bowels, and because of the differences in the height of the parts where they are located, the parts of the limbs that are affected are also different. Cervical spinal cord injury mainly affects the upper limbs, trunk and lower limbs, so it often causes quadriplegia. Thoracic spinal cord injury affects the trunk and lower limbs, while injury to the lumbar spine, especially the nerves below the waist, mainly affects the lower limbs, in which cervical and thoracic spinal cord injury belongs to high-level nerve injury, while the lumbar spine belongs to low-level nerve injury. Cervical and thoracic spinal cord injuries compress the spinal cord, while lumbar spinal cord injuries tend to compress the nerve roots, so the nature of the performance of these injuries is also different, for example, cervical spinal cord injuries manifested in the loss of sensation in the limbs, paralysis, paralysis, and dysfunction of muscle function and diaphragm. The injury of lumbar spinal cord lumbar nerve often causes unilateral paralysis of limb sensation, dull sensation, or muscle weakness, and the lower limbs are often accompanied by pain, which is more obvious. Therefore, due to the different parts of the cervical, thoracic and lumbar regions, the nature of the compressed nerves and spinal cord are also different, and the corresponding segments and symptom characteristics are also different.
