We prove the conical differentiability of the solution to a bone
remodeling contact rod model, for given data (applied loads and
rigid obstacle), with respect to small perturbations of the cross
section of the rod. The proof is based on the special structure of
the model, composed of a variational inequality coupled with an
ordinary differential equation with respect to time. This
structure enables the verification of the two following
fundamental results: the polyhedricity of a modified displacement
constraint set defined by the obstacle and the differentiability
of the two forms associated to the variational inequality.
