论文摘要
连续骨重塑是预测机械刺激对骨密度演化的影响的重要工具。尽管基于连续骨重塑的许多研究，仅考虑了仅取消骨的建模，但这项工作介绍了一种模拟的方法，还可以进行皮质骨和两种骨骼的相互作用。骨型之间的区别是通过引入初始体积分数来做出的。一个简单的点示例用于研究新型模型选项的行为以及近端股骨示例，其中两种骨骼类型的相互作用均使用初始密度分布来证明。提出的模型选项的结果表明，对皮质骨的考虑会明显改变取消骨的密度演化，因此不应被忽略。
Continuum bone remodelling is an important tool for predicting the effects of mechanical stimuli on bone density evolution. While the modelling of only cancellous bone is considered in many studies based on continuum bone remodelling, this work presents an approach of modelling also cortical bone and the interaction of both bone types. The distinction between bone types is made by introducing an initial volume fraction. A simple point-wise example is used to study the behaviour of novel model options, as well as a proximal femur example, where the interaction of both bone types is demonstrated using initial density distributions. The results of the proposed model options indicate that the consideration of cortical bone remarkably changes the density evolution of cancellous bone, and should therefore not be neglected.
