1, spinal cord shock Transient dysfunction after injury, manifested as flaccid paralysis, loss of sensation, movement, reflexes and sphincter function below the plane of injury, with gradual recovery over minutes, hours or a little longer, until complete recovery, generally leaving no sequelae. 2, spinal cord contusion and spinal cord compression clinical most common. After the injury, there is a partial or complete loss of sensation, movement, reflexes and sphincter function below the plane of injury, either unilaterally or bilaterally, mostly in the same plane bilaterally. The prognosis is determined by the extent of the spinal cord injury and the time to release the pressure. In general, spastic paralysis gradually evolves after 2-4 weeks, with increased muscle tone, hyperactive tendon reflexes, and pathological cone bundle signs. The thoracic spinal cord injury manifests as paraplegia, the cervical segment injury manifests as tetraplegia, the upper cervical segment injury manifests as spastic paralysis of the limbs, the lower cervical segment injury manifests as flaccid paralysis of the upper limbs and spastic paralysis of the lower limbs. 3, spinal cord hemisection signs below the plane of injury ipsilateral limb motor and deep sensory loss, the contralateral limb pain and temperature loss. 4.Spinal cord rupture The complete loss of sensation, movement, reflexes and sphincter function below the plane of injury. 5.Spinal cord cone injury Adult spinal cord terminates at the lower edge of the 1st lumbar vertebral body. When the 1st lumbar vertebra is fractured, the spinal cord cone can be damaged, manifesting as loss of perineal skin saddle sensation, sphincter function and sexual dysfunction, while the sensory and motor functions of both lower limbs remain normal. The latest key treatment view: The key to spinal cord injury is in the injury to the spinal cord. Even if the spinal deformity heals while the spinal cord is intact, the overall impact on the patient’s life and work is not significant. Treatment should always be done: the first concern is to protect the spinal cord, repair the spinal cord, and repair function, which is the first priority. Then comes internal spinal fixation surgery to maintain good spinal stability and good anatomical repositioning of the spine. A good and most aesthetic internal fixation of the spinal nail bar does not equal the best restoration of spinal cord function. Intravenous high-dose histone ganglioside + nerve growth factor + intrathecal injection of adenosylcobalamin, etc., is recommended for at least 3 months – 6 months or more depending on the condition. Intrathecal shock ganglioside + methylprednisolone and other potent groups are recommended 1-2 times a week. 10 times a course. Cell transplantation should be performed as early as possible (starting 2-4 weeks after spinal cord injury): 1 intravenous mesenchymal cell transplant + 1 intrathecal nerve cell + 1 intrathecal mesenchymal cell transplant (2 weeks/course, repeat the next course every 1-2 months. A minimum of 3-4 courses of treatment is recommended). For patients with mild spinal cord injury, it is more important to actively receive the above comprehensive neuroprosthetic treatment (local medication + intravenous high-dose group medication + cell transplantation + high-dose rehabilitation training treatment) within 3 years after the injury to maximize functional improvement, reduce the burden on the family and improve the quality of life and work of the individual. After the acute phase of spinal cord injury, it is a chronic pathological development process. In the acute and subacute phases after injury, the patient is in a self-repair process for 3-6 months. 6 months-1 year or more is the chronic phase, where the spinal cord injury condition is in a chronic pathological development process. Therefore, the chronic stage/late stage spinal cord injury, if not actively treated, the condition itself may still gradually worsen or even deteriorate (sensory, motor, vegetative nerve function, etc.). Half a month – 6 months after the injury is the golden period for nerve repair treatment.
