An injectable calcium phosphate cement (CPC) with excellent radiopacity was proposed by introducing a novel radiopacifier, strontium carbonate, into the powder phase of CPC. The results showed that the cement showed improved radiopacity even when the content of strontium carbonate was only 8 or 12wt.%. The addition of 8 or 12wt.% strontium carbonate clearly improved the injectability and compressive strength of the cement. Furthermore, the addition of strontium carbonate influenced the pore distribution in the cement. An injectable CPC containing 8 or 12wt.% strontium carbonate has the potential for use in procedures such as vertebroplasty and kyphoplasty.
通过将一种新型的射线不透光剂碳酸锶引入磷酸钙骨水泥（CPC）的粉末相中，提出了一种具有优异射线不透性的可注射磷酸钙骨水泥。结果表明，即使碳酸锶的含量仅为8%或12%（重量），该骨水泥的射线不透性也有所改善。添加8%或12%（重量）的碳酸锶明显改善了骨水泥的可注射性和抗压强度。此外，碳酸锶的添加影响了骨水泥中的孔隙分布。含有8%或12%（重量）碳酸锶的可注射CPC有潜力用于椎体成形术和后凸成形术等手术。
