通过在粉末状磷酸钙骨水泥（CPC）中引入一种新型的不透射线剂碳酸锶，制备了一种具有良好不透射线性的可注射型CPC。结果表明，即使当碳酸锶的含量仅为8或12重量%时，水泥也显示出改善的不透射线性。添加8或12重量%的碳酸锶明显改善了水泥的可注入性和抗压强度。此外，碳酸锶的加入影响了水泥中的孔隙分布。一种可注射CPC，其包含8或12重量%的碳酸锶具有在诸如椎体成形术和椎体后凸成形术的过程中使用的潜力。(c)2007 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
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 12 wt.%. The addition of 8 or 12 wt.% 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 12 wt.% strontium carbonate has the potential for use in procedures such as vertebroplasty and kyphoplasty. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd.
