Because changes in the mechanical properties of bone are closely related to trabecular bone remodeling, methods that consider the temporal morphological changes induced by adaptive remodeling of trabecular bone are needed to estimate long-term fracture risk and bone quality in osteoporosis. We simulated bone remodeling using simplified and pig trabecular bone models and estimated the morphology of healthy and osteoporotic cases. We then displayed the fracture risk of the remodeled models based on a cumulative histogram from high stress. The histogram showed more elements had higher stresses in the osteoporosis model, indicating that the osteoporosis model had a greater risk.
由于骨力学性能的变化与小梁骨重塑密切相关,因此需要考虑小梁骨适应性重塑引起的时间形态变化的方法来评估骨质疏松症的长期骨折风险和骨质量。我们使用简化的猪小梁骨模型模拟骨重塑,并估计健康和骨质疏松病例的形态。然后,我们基于高应力累积直方图展示了重塑模型的骨折风险。直方图显示,骨质疏松模型中有更多元素具有更高的应力,这表明骨质疏松模型具有更大的风险。
