Estimation of various parameters of fractured femur with different load conditions using Finite element analysis

Generally in medical applications, sensitivity in detecting medical problems and accuracy of detection are often in conflict. The aim of research work is to analyze the biomechanical behavior of the femur implant assembly during fixation of a simple transverse subtrochanteric fractured femur. To study the bio-mechanical activities of the femur and the implant gathering Finite element Analysis tool is used. The “standardized femur” is downloaded from repository of the Society of Bio-Mechanical Engineers and subsequently repaired to make it usable for this Finite Element Simulation. Finite element simulation software ANSYS and the modeling software Unigraphics are used for the present study. A static linear finite element analysis and non-linear contact analysis performance is used to study the intact femur and fractured femur with implant assembly respectively. Deflection, stress and strains are considered from implant. The present work has considered the full femur and modeled with non-homogeneous material properties for the bone material. The displacement and principle stress on the proximal femur have been compared with the intact model.
