Damaged-bone remodeling theory: Thermodynamical approach. (English) Zbl 0978.74053
Summary: The bone remodeling process is generally viewed as bone material response to functional demands and muscle attachments by continual process of growth, reinforcement and resorption which occur in living situation. Everyday activities damage bone, and this damage is normally repaired in a continuous remodeling process. When an imbalance in this remodeling process occurs, bones may become more susceptible to fracture. Here we establish a relationship between induced microdamage and adaptive bone remodeling. A thermodynamic theoretical framework is provided as a basis for consistent formulation of bone remodeling, involving chemical reactions and mass transfer between two constituents in the presence of microcracks.
