The selection of a patient-specific optimal implant during preoperative planning requires the consideration of geometrical and biomechanical criteria. In particular, the selected implant should lead to a physiological stress distribution in the bone, in order to avoid a degeneration of bone tissue and eventually a loosening of the implant or a fracturing of the bone.
This work presents the first planning system that allows for an implant selection based on the patient-specific prediction of the stress distribution. The system provides a virtual 3D planning environment, where the physician can interactively insert implants into the bone. During this process, the system instantaneously computes and visualizes the resulting stress distribution. For the realization of this computational steering environment, novel interactive simulation and visualization methods have been developed.
