Application of theories simulating the bone remodelling process (BRP) requires a knowledge of the correlation between the density of bone and its mechanical properties. The correlations that have been used so far are based on the pooled results of measurements using both human and bovine specimens [1]. It has been shown, however, that pooling of such results from different species is inappropriate [2]. In view of this, the first objective of Part II of this study, is to establish the density-property correlations based exclusively on the experimental results from human bone specimens and to investigate the influence of the nature of the correlations on the stability of the simulated BRP.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
