Scientists are studying new formulas for acrylic copolymers and compounds in order to obtain efficacious, multi-use bone cements with reduced side effects. Acrylic bone cements based on polymethylmetacrylate (PMMA) have been traditionally used in hip replacements in order to set the prothesis inside the bone. On the other hand, with new techniques such as vertebroplastia, the cement is injected into an affected vertebra by means of long and narrow needles, visualized with X rays.
