What are the risks of severe scoliosis surgery?

There are many risks associated with severe scoliosis surgery, including but not limited to nerve damage, massive bleeding, infection, visceral injury, spinal instability, implant failure or displacement, and anesthesia risks. 1. Nerve damage Due to the close proximity of the spine to the spinal cord, the spinal cord or nerve roots may be damaged during surgery, resulting in sensory or motor dysfunction and possibly paralysis. 2. Severe bleeding Spinal surgery involves a large number of blood vessels and nerves, which may occur during surgery and require blood transfusion or other hemostatic measures. 3. Infection may occur during or after surgery and requires antibiotics and other treatment measures. 4. Visceral injury In some extremely severe scoliosis surgery, due to anatomical variations, adjacent internal organs such as lungs, esophagus, heart, etc. may be damaged. 5. Spinal instability may occur after surgery, requiring further fixation and fusion surgery. 6. Implant failure or displacement The metal rods, screws and other devices implanted in the operation may be loose, displaced or broken, and need to be repaired or replaced. 7. Anesthesia risk Due to the long operation time and trauma, the use and management of anesthetics also bring certain risks. Please note that these risks do not necessarily occur. Doctors will formulate surgical plans based on the patient's specific conditions and reduce surgical risks as much as possible. At the same time, patients should also fully understand the surgical risks and make preoperative preparations and postoperative rehabilitation.
