COMPUTER SIMULATION OF A BONE REMODELING MODEL INCLUDING CELLULAR ACCOMMODATION EFFECT

A regulatory mechanism for mechanical adaptation of trabecular bone proposed by Huiskes and collegues [1] is implemented and studied in a MATLAB code. In addition to simulating the Osteocyte mechanosensory role and separation of Osteoclast and Osteoblast activity as proposed in [1], we improved this theory by including effect of Turner’s cellular accommodation [2]. We obtained trabecular-like structures for different loading conditions. The model was able to predict stress shielding and also showed qualities of global mechanical optimality.
