Biomechanical analysis of the human femur bone during going upstairs and sitting down

Biomechanics is a field that includes disciplines of engineering mechanics and biology and utilizes the tools of physics, mathematics, and engineering to describe the properties of biological materials. Finite element modeling has been widely used to describe the mechanical behavior of the long bones which have been created from CT (Computer Tomography) images In this study a three dimensional model of the human femur bone has been developed and the data associated with the hip contact forces for going upstairs and sitting down during one cycle has been employed on the femur bone in order to investigate behavior of the femur bone during these activities. The finite element results (stresses) are obtained and compared with previous studies. The behavior of the stresses that obtained in the present study is similar to those found in the literature The results of the analysis are helpful for the orthopedic surgeon to understand the biomechanical behavior of the femur bone and also important for surgeon in femur surgeries and bone prosthesis.
