"Fractures of the vertebrae -- the bones of the spine -- are relatively common in people with osteoporosis and spinal tumors, but few treatment options are available. Vertebroplasty is a relatively new procedure in which a special cement is injected into weakened or collapsed vertebrae to harden the bone. The cement used, polymethylmethacrylate (PMMA), has been used to reconstruct bone during surgery for at least 20 years."
Not quite the same stuff as concrete used in sidewalks!
