Simulation of adaptive bone remodeling by using cellular automata

In this study, a new computer simulation model of the bone remodeling adapting to mechanical environment by using the cellular automata is proposed. Finiteelements of FEM are further subdivided into smaller cells which are stated as bone tissue, bone cell or empty space. States of the cells are changed automatically by a set of rules as similar as bone remodeling rules. While the set of rules is changed due to stress level of each element, the bone density is changed adapting to the stress. Efficiency of the simulation model is demonstrated applying it to a bone remodeling problem of a human femoral head.
