Personalized Finite Element Analysis of an Endo-Exo Prosthetics System under Conditions of Osseointegration

  • Published:
Biomedical Engineering Aims and scope

A method for personalized analysis of the stress−strain curve of the endo-prosthetics subsystem of an endo-exo prosthetics system implanted into the femoral medullary canal is presented. The method is based on the analysis of CT scans. The results of test application of the method are presented. The goal of the study is to determine the reliability and the strength margin of the implant−bone system under conditions of osseointegration in a walking patient. The study has shown that the bone density is sufficiently high to meet the requirements for the endo-exo femur prosthesis; the strength margin of the bone is 11.5.
