Preoperative Simulation of the Hip-Stem Osseointegration Based on the Physiological Loading Conditions

摘要: Individualized approach and quality assurance in endoprosthetics remains a challenge. Computer-aided simulation of the mechanical loading bones bony integration implant as well preoperative prognosis longevity has high clinical socioeconomic impact. The finite element method provides precise tool for analysis stress distribution bone with without stem under any given conditions. Thus, determination conditions, which correspond to real bone, is utmost important prediction osseointegration. presented investigation devoted biomechanical investigations osseointegration titan hip-joint replacement using physiological determined human femur based on bending-minimization principle. Using levels different types intact two cases locomotion, area calculated comparison before after virtual implantation relative micro-motion bone/implant interface. results FE correlate measurements areas several explanted stems available present some data. work foundation long-term stability total joint and, furthermore, allows an individualized endoprostheses.
