As for the risks of surgery, just like flying in an airplane, even the best specialists cannot guarantee that the surgery will be successful. Like any other surgery, spine surgery inevitably involves certain risks and complications: such as more bleeding, spinal nerve injury, adverse reactions to anesthesia and pain medications, pneumonia and other complications, but such complications are in the few percent. With the efforts of several generations, our spine surgery department has a team with strong technical strength, sophisticated collaboration in intraoperative monitoring and postoperative treatment, and monitoring of motor evoked potentials, so that the risks and complications of surgery are greatly reduced, so spine surgery is still relatively safe in our hospital.
