For patients with intravertebral space, the risks of surgery are: first, it may lead to damage to the spinal cord and nerve roots in the spinal canal; second, it may lead to cerebrospinal fluid leakage; third, it may also lead to infection in the spinal canal. For patients undergoing intraspinal surgery, if there is obvious damage to the spinal cord and nerves, it may lead to increased numbness and pain in the limbs, and in severe cases, it may also lead to loss of sensation and movement in the limb areas. If the intraspinal space is high, i.e., located above the thoracic spine, the spinal cord and nerve injury may also lead to urinary and fecal dysfunction. If the dural sac is not completely closed after surgery for intradural occupancy and does not recover completely, this situation can easily lead to cerebrospinal fluid leakage, and if the leakage of cerebrospinal fluid causes infection, it can lead to intradural infection, and this situation will lead to significant numbness and pain in the limbs, which will seriously affect the quality of life of the patient.
