This research was directed towards a study of the lower limb of the human body through the 3-D modeling and finite element analysis of the tibia, Finite element analysis is used to evaluate the stresses and displacements of human tibia bone under physiological loading. Three-dimensional finite element models obtained by using computed tomography (CT- Scan) data which consisting thorough description about the material properties of bone and density of bone tissues which is very essential to create accurate and realistic geometry of a bone structure. Therefore, in this study, CT - Scan data of patients Tibia Bone (Healthy, broken tibia bone after 1month and 2 month of surgery Tibia Bone) are used to develop three-dimensional finite element models of the left proximal tibia bone, and half of an average body weight applied on Tibia Bone . Finite Element Analysis conducted to calculate the Equivalent Von-Mises Stress, Maximum Principal Stress, Total Deformation and Fatigue Tool from the whole proximal tibia bone and comparing the results.
