Book Finite Element Analysis of a Femur to Deconstruct the Design Paradox of Bone Curvature

Download or read book Finite Element Analysis of a Femur to Deconstruct the Design Paradox of Bone Curvature written by Sameer Jade and published by . This book was released on 2012 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The femur is the longest limb bone found in humans. Almost all the long limb bones found in terrestrial mammals, including the femur studied herein, have been observed to be loaded in bending and are curved longitudinally. The curvature in these long bones increases the bending stress developed in the bone, potentially reducing the bone's load carrying capacity, i.e. its mechanical strength. Therefore, bone curvature poses a paradox in terms of the mechanical function of long limb bones. The aim of this study is to investigate and explain the role of longitudinal bone curvature in the design of long bones. In particular, it has been hypothesized that curvature of long bones results in a trade-off between the bone's mechanical strength and its bending predictability. This thesis employs finite element analysis of human femora to address this issue. Simplified human femora with different curvatures were modeled and analyzed using ANSYS Workbench finite element analysis software. The results obtained are compared between different curvatures including a straight bone. We examined how the bone curvature affects the bending predictability and load carrying capacity of bones. Results were post processed to yield probability density functions (PDFs) for circumferential location of maximum equivalent stress for various bone curvatures to assess the bending predictability of bones. To validate our findings on the geometrically simplified ANSYS Workbench femur models, a digitally reconstructed femur model from a CT scan of a real human femur was employed. For this model we performed finite element analysis in the FEA tool, Strand7, executing multiple simulations for different load cases. The results from the CT scanned femur model and those from the CAD femur model were then compared. We found general agreement in trends but some quantitative differences most likely due to the geometric differences between the digitally reconstructed femur model and the simplified CAD models. As postulated by others, our results support the hypothesis that the bone curvature is a trade-off between the bone strength and its bending predictability. Bone curvature increases bending predictability at the expense of load carrying capacity.

Book Elastic Properties of the Human Femur

Download or read book Elastic Properties of the Human Femur written by Annette Bretin and published by . This book was released on 2019-02-04 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Patient-specific finite element modelling of bone is a promising method for surgical planning, implant design and the prediction of bone remodelling or fracture risks, yet the assignment of material properties is challenging. Bone is a complicated structure with direction-dependent, inhomogeneous material properties, influenced by compositional, geometrical and architectural aspects. This volume focuses on a density-based assignment of orthotropic bone properties. Elasticity-density relationships in homogenized femoral zones were examined to evaluate the orthotropic density-dependence of the nine elastic material constants locally. Cortical bone samples were tested in compression and torsion tests using videoextensometry to determine the elastic constants. The elastic properties of cancellous bone were predicted by micro finite element analysis. All determined constants were correlated to the radiological bone mineral density of each sample, which was determined by quantitative computed tomography. The trabecular eigensystem was investigated for each cancellous zone to assign the mean directionality of trabecular fabric. The results can be beneficial for density-based orthotropic material assignment in femoral patient-specific finite element models.

Book Holographic Deformation Analysis of the Human Femur

Download or read book Holographic Deformation Analysis of the Human Femur written by and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deformations of the neck and head of the human dried femur were measured and analyzed with loads applied at the femoral head. Particular attention was paid to measurements of bones with osteoporosis. We used double exposures or real-time holographic interferometry to measure precisely. The distal part of each femur was embedded in super hard plaster, and the load was applied at the femoral head. In order to better simulate the situation of a femur under physiological muscles, we used the 3D finite element method (FEM) for our analyses. After modeling the femur, which consisted of meshing as eight noded elements for each section of diaphysis, we used the 3D FEM to calculate stress and strain. We obtained the following results : (1)the deformations increased with the progress of osteoporosis;(2) femur with osteoporosis showed obvious rotational components in the femoral shaft and (3) a compressive stress distribution could be found at the medial side of the diaphyseal region by using the FEM.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, numerous scientific investigations have studied the anatomical, biomechanical and functional role of structures involved in the human knee joint. The Finite Element Method (FEM) has been seen as an interesting tool to study and simulate biosystems. It has been extensively used to analyse the knee joint and various types of knee diseases and rehabilitation procedures such as the High Tibial Osteotomy (HTO). This work presents a review on FEM analysis of the human knee joint and HTO knee surgery, and discusses how adequate this computational tool is for this type of biomedical applications. Hence, various studies addressing the knee joint based on Finite Element Analysis (FEA) are reviewed, and an overview of clinical and biomechanical studies on the optimization of the correction angle of the postoperative knee surgery is provided.
