What is the definition or description of: ct-guided vertebroplasty?

A vertebroplasty is : The repair of a fractured vertebra that has been compressed by placing a substance commonly referred to as " bone cement" though a needle into the vertebra to eliminate pain from that fracture by stabilizing it and in this type the procedure is done or needle directed under the use of an imaging technique known as a ct or cat scan.

Vertebroplasty: Ct-guided vertebroplasty is a procedure performed inside the ct-scanner where bone cement (called pmma) is injected through a needle through the skin and the muscle, via the pedicle (a piece of bone connecting the back-to-front of the spine) into the vertebral body to strengthen it, or to treat a fracture that caused the bone to be compressed. The ct will tell the surgeon exactly where to aim.
