  Bone is a living material. It adapts, in an optimal sense, to loading by
changing its density and trabeculae architecture - a process termed
remodelling. Implanted orthopaedic devices can significantly alter the loading
on the surrounding bone, which can have a detrimental impact on bone ingrowth
that is critical to ensure secure implant fixation. In this contribution, a
computational model that accounts for bone remodelling is developed to
elucidate the response of bone following a reverse shoulder procedure for
rotator cuff deficient patients. The physical process of remodelling is
modelled using continuum scale, open system thermodynamics whereby the density
of bone evolves isotropically in response to the loading it experiences. The
fully-nonlinear continuum theory is solved approximately using the finite
element method. The code developed to model the reverse shoulder procedure is
validated using a series of benchmark problems.
