T-D401. The patient was lying prone, and the involved vertebral segments were located by Kirschner wire and C-arm x-ray machine fluoroscopy. The entry point was marked, disinfected, and local anesthesia applied. The bone scan and tomography showed abnormal concentration and compressibility of imaging agents in L2 vertebrae (Figure 1).

At the beginning of the operation, the puncture needle was inserted through the right pedicle until it reached the midline of the vertebral body in the positive position (Figure 2).

At this time, the patient developed transient low back pain, which was relieved after a few minutes, and fluoroscopy showed that the bone cement extended along the posterior longitudinal ligament space and epidural space (Figure 3).
Postoperative CT scan 3D reconstruction showed bone cement infiltrating the epidural space of the spinal canal and distributed along the posterior longitudinal ligament from T12 to L2 (A-D) and the filling of bone cement in the posterior spinal canal of the L2 vertebral body(E-K).
