Bone-particle-impregnated bone cement specimens (up to 30% by weight) were characterized by various test methods. The experimental bone cement showed decreased crack propagation rates and increased Young's modulus, while the ultimate tensile strength and impact strength were decreased. The viscosity could be adjusted by adding initiators lost when substituting the PMMA powder with bone particles. The present study warranted further in vivo experiments on the possibility of tissue ingrowth for which the new bone cement was developed.
对含骨颗粒的骨水泥标本(重量占比高达30%)采用多种测试方法进行了表征。实验性骨水泥的裂纹扩展速率降低,杨氏模量增加,而极限拉伸强度和冲击强度降低。当用骨颗粒替代聚甲基丙烯酸甲酯(PMMA)粉末时,可通过添加损失的引发剂来调节粘度。本研究有必要进一步开展体内实验,以探究新开发的骨水泥促进组织向内生长的可能性。
