The patient, a male, was unable to walk before surgery and supported a double crutch to get down. Preoperatively, severe lumbar scoliosis was seen. Postoperatively, the scoliosis was completely corrected. One week later, he was discharged from the hospital, threw away the double crutches and could walk. One month later, the back pain was basically relieved, and he could walk around Beihai Park once a day.
