Abstract

Since the 1980s electrostimulative systems are used to improve bone regeneration. This concept is now being implemented in a total hip revision system to accelerate bone regeneration after surgery. In prior works, an electrostimulative acetabular cup has been introduced and optimized. Nevertheless, the stimulation- and thus the optimization concept for the acetabular cup cannot be applied to the femoral part in the thigh bone. Therefore, this paper presents a computational model of the electrostimulative hip stem as well as an approach to optimize the field distribution in close proximity to the femoral bone.
