Abstract
The main purpose of this work is to study the capacity of bone to adapt itself to a variety of mechanical loadings. An analysis of the most important bone adaptive remodeling formulations was developed, improving their mechanical consistency, this study has been done in 2D and 3D, observing the validity of bidimensional models.

A new theory, which incorporates different levels of anisotropy, is proposed. It is based on an exponential law, which is closest to the reality. The new model's density distributions, using the proximal femur as example, are very similar to other models, but the stability and convergence is improved with this new formulation.
