Various continuum bone remodelling algorithms applied to the proximal femur in two and three dimensions
This study investigates the behaviour of bone when it is subjected to mechanical loading. This is important in fields such as orthopaedics and implant design. Various models of bone remodelling are discussed, and a strain energy based as well as a strain remodelling based algorithm are applied in two and three dimensions. Properties such as dependence on initial conditions, development of physiologically realistic solutions and existence of long-term steady states are investigated. The strain based model has some advantages in that it is defined in terms of physiologically meaningful and measurable parameters and that it develops a long-term steady state solutions different from the case where the bone either resorbs completely or reaches cortical density.
