Lattice continuum model for bone remodeling considering microstructural optimality of trabecular architecture

摘要

To consider microstructural changes of cancellous bone in remodeling mechanics, a lattice continuum model of cancellous bone considering the optimality at microstructural component was discussed based on uniform stress hypothesis. The trabecular architecture is modeled as a lattice structure of rod/beam-like element that is embedded in the continuum in the context of the couple stress theory. For a vertebral body modeled by quantitative measurements of the trabecular architecture, a remodeling simulation was conducted under the repetitive bending with compression.
