76-year-old man with L1 vertebral body fracture.

A, Lateral conventional radiograph after initial vertebroplasty. After administration of 3 mL of cement via a left unilateral transpediculate approach, the cement opacifies the anterior portion of the vertebral body (arrow). The patient reported complete pain relief after the procedure.

B, Lateral conventional radiograph after repeat vertebroplasty. After administration of an additional 1.2 mL of cement via a right unilateral transpediculate approach, the filling pattern has changed from A to include prominent posterior opacification. The patient reported moderate pain relief after the procedure.
