A 47-year-old female with L5/S1 lesions was managed by surgery with posterior-only approach. The preoperative imaging data (a X-ray, b CT, and c MRI) showed severe vertebral destruction and dural sac compression at L5/S1. The postoperative (d) radiography and (e) CT showed that internal fixation instrument and grafted bone were in good position. f The X-ray indicated solid bony fusion at 12 months after surgery. At the 36 months after surgery, (g) CT and (h) radiography showed solid bony fusion without signs of fixation failure. At the final follow-up (86 months after surgery), (i) CT and (j) radiograph illustrated solid bony fusion and no obvious angle loss with good fixation position
