Answer

Depending on the manufacturer, there can be different methods to make the cement. Depending on the agent of choice, both polymethylmethacrylate (PMMA) and barium sulfate (opacifying agent) should be made as per the manufacturer's instructions. Slowly inject this mixture until the vertebral body is well filled, making certain to stop before PMMA leaks posteriorly into the epidural area or significantly fills a vein.

An important consideration is the volume of cement used to fill the vertebral body. Pain relief is not associated with cement volume, thus attempting to fill the vertebral body as completely as possible is not necessary. [19]
