摘要
椎体成形技术的快速发展使得用以治疗由骨质疏松引发的椎体骨折的PMMA骨水泥面临极大的需求,尤其是我国人口老龄化加剧,迫切需要赋予PMMA骨水泥一定生物活性,以延长有效的支撑时间,避免二次手术。阐述了羟基磷灰石、磷酸三钙、生物陶瓷等活性组分对PMMA骨水泥改性后,其力学性能和生物活性方面的研究现状,为其在临床应用奠定了基础。
It is emergency to develop a bioactive PMMA-based bone cement, which can prolong the implantation time and avoid the second surgery, along with the rapid development of percutaneous vertebroplasty on the vertebral fractures caused by osteoporosis in our aging population. In this article, the mechanical property and bioactivity of PMMA-based cement incorporated with bioactive materials such as hydroxylapatite, calcium phosphate, bioceramics were investigated for clinical application.
