The spinal cord is not regenerable because the spinal cord belongs to nerve cells, and nerve cells have a characteristic that, like cardiac muscle cells, cannot be regenerated once they are necrotic. So as far as this characteristic is concerned, if certain lesions are found in the spinal cord, including spinal cavernous disease, spinal vascular malformation, spinal cord tumors and other changes of various natures, corresponding treatment must be carried out in a timely manner to save the nerve cells that are not completely necrotic as much as possible and to reduce the probability of sequelae. For the cells that are already ischemic and necrotic, there is no single modality that can alleviate and cure them for the time being. It must be noted that functional exercise should be carried out in the process of treatment, because functional exercise allows other normal cells to compensate for some of the functions of necrotic cells, which is more conducive to the occurrence of compensatory function in the early stage, and the specific amount of compensation is closely related to the rehabilitation treatment, and the correct rehabilitation functional exercise will help the emergence of compensatory capacity in the later stage.
