Balloon kyphoplasty and vertebral stenting

The idea of this method consists of using the balloon catheter connected with a titanium spring - stent. After expanding the broken vertebral body with pressure from the fluid, the stent expands together with a balloon. After achieving the necessary degree of reduction, the balloon can be removed, and the expanded stent supports the inner structure of the vertebrae. Then this cavity is filled with bone cement, and vertebral fracture is reliably fixed.

Besides maintaining the height of the vertebrae after the balloon deflation and before cement injection, stent performs another important function. By squeezing bone trabeculae, stent prevents communication between the vertebral cavity and venous drainage, and thus prevents cement leak.
