Fig 2. Lateral view of the L3 vertebral body at the conclusion of vertebroplasty demonstrates cement extending throughout the anterior and middle portions of the vertebral body, filling a large cleft. The presence of the cleft is confirmed by the solid appearance and sharp outer borders of the cement bolus.

Fig 3. Lateral radiograph of the lumbar spine following a severe acute exacerbation of the patient’s back pain revels that the posterior portion of the vertebral body has collapsed further since the prior MR imaging, with 1 cm of anterior displacement of the intravertebral cement, which now projects well past the anterior spinal line. Note the reduced attenuation in the inferior L3 vertebral body corresponding to where the cement was initially located as well as a small amount of cement remaining in the original location (arrow).
