BACKGROUND
Acrylic PMMA bone cement is an essential component in cemented implants and formed the cement-bone and cement-implant interfaces. The information on the fracture parameters of PMMA bone cement would be decisive for all doctors, researchers, and orthopaedic surgeons.
PURPOSE
This review aims to indicate the parameters responsible for the variation in the fracture toughness of PMMA bone cement. This mini-review also points out some limitations of the earlier published research article, which can be added in the future analysis and can be helpful to get the more realistic data of the fracture parameters of PMMA bone cement.
CONCLUSION
Different mixing techniques, storage medium, temperature, loading conditions, frequency and environment, cement viscosity, type of specimen, and the ASTM standards (shape, size, and geometry), constituents, loading rate, and cement porosity were the critical parameters to affect the fracture toughness of PMMA bone cement. This study will also be helpful to increase the structural integrity of PMMA bone cement and the cemented implant.
背景
丙烯酸聚甲基丙烯酸甲酯骨水泥是骨水泥型植入物的重要组成部分，形成了骨水泥 - 骨和骨水泥 - 植入物界面。聚甲基丙烯酸甲酯骨水泥断裂参数的信息对所有医生、研究人员和骨科医生来说都至关重要。
目的
本综述旨在指出导致聚甲基丙烯酸甲酯骨水泥断裂韧性变化的参数。本小型综述还指出了早期发表的研究文章的一些局限性，这些局限性可在未来分析中补充，有助于获得更符合实际的聚甲基丙烯酸甲酯骨水泥断裂参数数据。
结论
不同的混合技术、储存介质、温度、加载条件、频率和环境、水泥粘度、试样类型以及ASTM标准（形状、尺寸和几何形状）、成分、加载速率和水泥孔隙率是影响聚甲基丙烯酸甲酯骨水泥断裂韧性的关键参数。本研究也将有助于提高聚甲基丙烯酸甲酯骨水泥和骨水泥型植入物的结构完整性。
