“…The experimental models that involve the study of tensile or compressive loading for fracture analysis require securing the femur in a solidifying base such as plaster of paris or dental powder to avoid the deformation and destruction. The fixation of the specimens is the key to the success of the tensile test and torsion test [8]. This not only helps overcome the stress concentration but also obtain perfect specimens and good fixation effectiveness to ensure successful experiment result.…”

Background:Femur bone is an important part in human which basically gives stability and support to carry out all day to day activities. It carries loads from upper body to lower abdomen.Objective:In this work, the femur having composite structure with cortical, cancellous and bone marrow cavity is bisected from condyle region with respect to 25%, 50% and 75% of its height. There is considerable difference in the region chosen for fixing all degrees of freedom in the analysis of femur.Methods:The CT scans are taken, and 3D model is developed using MIMICS. The developed model is used for static structural analysis by varying the load from 500N to 3000N.Results:The findings for 25% bisected femur model report difference in directional deformation less than 5% for loads 2000N and less. In the study comparing fully solid bone and the composite bone, the total deformation obtained for a complete solid bone was 3.5 mm which was 18.7% less than that determined for the composite bone.Conclusion:The standardization for fixing the bone is developed. And it is required to fix the distal end always with considering full femur bone.
