[0002] For vertebral compression fractures, the traditional treatment method is bed rest, which takes a long time to recover, and is prone to complications especially for the elderly. Vertebroplasty is a method of percutaneous injection of bone cement into the vertebral body. It was first used clinically in my country in 2000.

In 1998, it was reported abroad that a cannula was introduced into the vertebral body, and an inflatable airbag bone tamping rod was inserted through the cannula to expand the collapsed vertebral body and produce a cavity. Then inject bone cement under a lower pressure. This techni...
