[Biomechanically induced stimulation of postoperative bone remodeling]

Bone remodelling after prosthetic surgery involving the skeleton should create a durable and intimate connection between the bone and the prosthesis. A prosthesis that is not adapted to the biological mechanics is known to cause growth reactions which may lead to failure of the biotechnical system. The stimulation of growth reactions by local, specific changes in loading is defined in this paper. Analogously to the classical laws of continuum mechanics a model for calculating the post-operative remodelling processes is developed.
