On the Features and Assumptions of Bone Remodelling Theories: Part I — Stability Analysis and Selection of Remodelling Stimulus

Abstract

Evidence of adverse bone adaptation after arthroplasty has led to an increasing interest in the study of the bone remodelling process (BRP). A number of theories have been developed to simulate the process [1,2,3], with the objective of computing the effect of a change in the mechanical environment on bone geometry (i.e., external bone remodelling) or bone material properties (i.e., internal bone remodelling). However, the application of the theories continues to demand critical evaluation of a number of their features and assumptions. Part I of this presentation deals with the analysis of the stability characteristics of the simulated BRP, and with the selection of the mechanical stimulus assumed to drive the process.
