Abstract

Samples of low viscosity poly(methyl methacrylate) (PMMA), graphite reinforced PMMA, and graphite reinforced low viscosity PMMA were evaluated for their compression strength and fracture toughness. These results were compared with two currently used plain PMMA bone cements. There were no statistically significant differences in compression strength between the five cements. Graphite reinforcement of plain cement produced a 32% increase in fracture toughness over plain cement. Graphite reinforcement of low viscosity cement also produced a significant increase in toughness (31%) over low viscosity cement with fiber reinforcement. However, low viscosity cement demonstrated significantly less fracture toughness than plain PMMA.

摘要

对低粘度聚甲基丙烯酸甲酯（PMMA）、石墨增强PMMA以及石墨增强低粘度PMMA的样品进行了抗压强度和断裂韧性评估。将这些结果与两种目前使用的普通PMMA骨水泥进行了比较。五种骨水泥在抗压强度方面没有统计学上的显著差异。普通骨水泥的石墨增强使其断裂韧性比普通骨水泥提高了32%。低粘度骨水泥的石墨增强也使其韧性比纤维增强的低粘度骨水泥显著提高（31%）。然而，低粘度骨水泥的断裂韧性明显低于普通PMMA。
