Palaces R-(R) 骨水泥使用三种市售混合技术（第一代、第二代和第三代）制备，以确定骨水泥的机械性能和孔隙率含量。压缩强度、弯曲强度和弯曲模量表示为空隙率的函数。研究发现，水泥结构内的孔隙体积是影响丙烯酸骨水泥物理性能的因素。水泥中的空隙体积越小，压缩和弯曲性能越好，因此骨水泥强度越高。结果发现，使用 Mitab Optivac (R) 或 Summit HiVac (R) 注射器系统在低于大气压 -72 至 -86kPa 的减压水平下混合水泥可获得最佳结果，水泥的孔隙率为 1.44-3.17%；抗压强度74-81兆帕；弯曲模量2.54-2.60 GPa；弯曲强度65-73 MPa。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
Palaces R-(R) bone cement was prepared using three commercially available mixing techniques, first generation, second generation and third generation, to determine the mechanical properties and porosity contents of the bone cement. The compressive strengths, bending strengths and flexural moduli were expressed as a function of void content. The volume of pores within the cement structure was found to be a contributing factor to the physical properties of acrylic bone cement. The lower the volume of voids in the cement the better the compressive and flexural properties, hence stronger bone cement. It was found that the best results were obtained from cement that had been mixed using the Mitab Optivac (R) or Summit HiVac (R) Syringe systems at a reduced pressure level of between -72 and -86kPa below atmospheric pressure, resulting in cement of porosity 1.44-3.17%; compressive strength 74-81 MPa; flexural modulus 2.54-2.60 GPa; and flexural strength 65-73 MPa.
