The cement is prepared and its consistency monitored until it's adequate for injection.
Carefully inject the bone cement (bilaterally), preferably without any pressure. The space is filled from anterior to posterior as the cannula is slowly retracted. The process is closely monitored to ensure that no cement leaks into unwanted areas such as the ventral venous system or epidural space.
Although complete filling of the vertebral body is the goal, it is not always possible or necessary.
