After the patient’s lumbar spine nerve injury, it can be recovered under general circumstances and difficult to recover under special circumstances, as follows: First, recoverable: general lumbar spine nerve injury is usually not serious, and after bed rest, lumbar spine braking and nerve nutrition treatment, the nerve injury can be gradually recovered. Second, not recoverable: special circumstances, such as lumbar burst fracture or lumbar dislocation, lumbar nerve complete disconnection, easy to make the lower limbs appear motor sensory, reflex abnormalities, and may even appear urinary and fecal disorders. In this case, nerve damage is usually difficult to recover, and even if the current hematopoietic stem cell treatment is used, only the function of urination and defecation will be restored to a certain extent, but the function of limb movement and other functions usually cannot be restored. Therefore, patients should pay attention to protect the lumbar nerves to avoid serious nerve injury.
