Abstract

Bone maintenance and remodeling are generally approached either as a structural optimization process or as a point-by-point material adjustment process in which the local tissue adjusts (as a continuum) to the local remodeling stimuli. We have recently found a way to bridge these two approaches, for a restricted class of remodeling stimuli. In this paper, we show a simple application of this correspondence in a geometry which represents an intramedullary stem under axial loading. This results in a prediction for critical prosthesis stiffness for bone maintenance around a prosthesis which is borne out by finite element simulations using the local remodeling equations.
