and keep it in the new uncollapsed position with the same "bone cement" used in hip and knee replacements. The cement is mixed from a powder and a liquid and the reaction that results is "exothermic" ie, it gives off heat. It is
therefore imperative that none of the cement (has a thick glue-like consistency) from leaking out into the windows formed by the flange-like extensions of the vertebral bodies ("intervertebral windows) which contain the nerves which go out and supply the body (both sensory and motor) or into the spinal column itself where the spinal cord sits (covered by meningeal linings)

This procedure is done on very severe compression fractures from age-related or disease-related (eg. kidney disease) osteoporosis as well as on vertebral bodies which are invaded by metastatic cancer.

I am unaware of the results of radiating areas which were previously treated with this procedure (as other adjacent vertebral bodies may become involved later and radiation therapy in general(perhaps not cyberknife, but this is not routinely used for vertebral bone mets) is not pin-point--adjacent areas get considerable radiation as well.

Why don't you put vertebroplasty into Google and PubMed and see what you come up with?

Hope this helped!
