A Mechanistic Model For Internal Bone Remodeling Exhibits Different Dynamic Responses In Disuse And Overload, Scott J. Hazelwood, R. Bruce Martin, Mark M. Rashid, Juan J. Rodrigo

Biomedical Engineering

Bone is a dynamic tissue which, through the process of bone remodeling in the mature skeleton, renews itself during normal function and adapts to mechanical loads. It is, therefore, important to understand the effect of remodeling on the mechanical function of bone, as well as the effect of the inherent time lag in the remodeling process. In this study, we develop a constitutive model for bone remodeling which includes a number of relevant mechanical and biological processes and use this model to address differences in the remodeling behavior as a volume element of bone is placed in disuse or overload. …
