About 200 million peoples around the world are affected by different types of bone diseases. Osteoporosis is one among them which is a low bone density disease which increases the porosity of the bone and leads to severe pain and fracture of the human bone. Women’s are most affected by this disease due to various reasons. It can be only predicted after the failure or fracture of the bone when the sudden impact of the load. The femur is the longest bone in the human body which is mainly affected by means of fracture due to osteoporosis. The strength of the bone mainly depends on its density and can be determined by the Bone Mineral Density (BMD) Test. Hence it is necessary to numerically predict the stress and deformation of bone for the osteoporosis patient in their daily activities. Nowadays many researches have been undergone in Finite Element Analysis (FEA) of human bone in order to predict the stress and deformation when subjected to various loads in daily life. In this work, Structural analysis is carried out on femur bone which is modelled from CT scan report and material properties are assigned from osteoporosis patient. The loading conditions are based on the force which exerts on the femur bone during routine activities. The analysis is carried out with two different boundary conditions and it is seen that the femur head and distal end of the femur is subjected towards maximum normal stress and deformation.
