    - A 60-year-old female who suffered a back injury and suffered back pain accompanied by restricted motion of the lumbar spine was admitted to the hospital for 2 days. a-b) Preoperative lumbar spine lateral X-ray film prompts: T12 vertebral wedge shape change. c-b) -Preoperative MRI shows T12 vertebral bone marrow edema as a fresh fracture. e-f) The T12 vertebral body was treated with PVP, unilateral pedicle puncture, and the injection of 3.9 ml of PMMA bone cement. Postoperative lumbar spine X-ray film showed that T12 had changed postoperatively, and the bone cement was well distributed.

    - A 68-year-old woman was admitted to the hospital after a week of backache due to a fall. a-b) Preoperative lumbar spine lateral X-ray film findings: L2 vertebral body wedge changes. c-d) Preoperative MRI showed L2 vertebral bone marrow edema as a fresh fracture. e-f) PVP treatment of L2 vertebral body, bilateral pedicle puncture, and injection of 5.0 ml of PMMA bone cement. Postoperative lumbar spine X-ray film showed that L2 had changed postoperatively, and the bone cement was well distributed.
