Abstract

We present a tool for hip joint replacement planning that allows the surgeon to rank the long-term stabil- ity of an implant, and we show the application of this tool in a clinical routine setting. The tool allows the surgeon to predict the load transmission of an implant to the patient-specific bone. It is used to select of a set of available implants the one that most closely replicates the physiological stress state in order to avoid stress shielding. Advanced simulation technol- ogy is combined with 3D visualization options to provide quick and intuitive understanding of the generated results. Interac- tive feedback rates and intuitive control mechanisms facilitate the finding of an optimal implant shape with respect to the patient’s specific anatomy. By restricting to a predetermined implant position, which is in accordance with the selected position in a real surgery, the surgeon can quickly analyze a number of different implants under varying load conditions.
