| Abstract | The present invention provides bioactive bone cements that not only have sufficient radiopacity, low physiological toxicity, and requisite mechanism strength, but also promote local bone in-growth. The bone cement utilizes strontium salts as radiopacifiers, and comprises a powder component and a liquid component. In an embodiment, the powder component comprises a strontium salt, poly(methyl methacrylate) (PMMA), and a polymerization initiator; and the liquid component comprises methyl methacrylate (MMA) as reactive monomers and a polymerization accelerator. |
