Comparison of Balloon Kyphoplasty and Vertebroplasty in Subacute Osteoporotic Vertebral Fractures

Balloon Kyphoplasty, a variant of Vertebroplasty, in which a balloon is first placed into the fractured vertebra and inflated with fluid in order to create a cavity. Then, the balloon are deflated and removed. This may restore part of the vertebral height loss due to the fracture and facilitate the injection of the cement with low pressure.

Vertebroplasty consisting in the percutaneous injection into the fractured vertebra of polymethylmetacrylate cement (the cement used to fix prosthesis in joint replacement) through a posterior route through the vertebral pedicles under radiological guidance
