Download or read book Evaluation of Adaptive Bone Remodeling After Total Hip Arthroplasty Using Finite Element Analysis written by Yutaka Inaba and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We compared equivalent stress and strain energy density (SED) to bone mineral density (BMD) in the femur after total hip arthroplasty (THA) using subject-specific finite element analysis (FEA). Equivalent stress and BMD were maintained in the distal femur after THA, whereas both decreased in the proximal femur. A significant correlation was observed between the rates of changes in BMD and equivalent stress before and after THA. Therefore, FEA can predict adaptive bone remodeling after mechanical loading changes. Additionally, we evaluated the effects of two different types of stem geometries (Zweymüller-type stem and fit-and-fill-type stem) on load distribution and BMD using the same method. Equivalent stress and BMD in the medial side of the proximal femur were significantly lower with the Zweymüller-type stem than with the fit-and-fill-type stem. Therefore, FEA can assess the effects of stem geometry on bone remodeling after THA. Moreover, we evaluated the effects of bone geometry on load distribution and BMD after THA. Equivalent stress in the medial side of the proximal femur was significantly lower in the stovepipe model implanted with large tapered wedge-type stems than in the champagne flute and intermediate models, and there was a significant loss of BMD in the stovepipe model. Therefore, a large tapered wedge-type stem and stovepipe femur may be associated with significant proximal BMD loss.

This book was released on 2008-08 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2006 in the subject Medicine - Biomedical Engineering, grade: 1.0, Technical University of Munich (LS Statik), course: Master of Science of Computational Mechanics, 94 entries in the bibliography, language: English, abstract: The process of adaptive bone remodeling can be described mathematically and simulated in a computer model, integrated with the finite element method. The main focus of this thesis is the implementation of a bone remodeling algorithm in MATLAB and ANSYS on the basis of FEM. The strain energy density is used as mechanical stimulus. The cortical and trabecular bone are described as continuous materials with variable density. This thesis can be divided into four main parts. The first part is due to the material properties of cortical and trabecular bone. The second part is about the remodeling theory and gives an historical review of the developed numerical approaches up to now. The implementation of the remodeling algorithm in ANSYS and MATLAB as well as its validation is topic of part three. In last main part, the algorithm is applied to a 2D FE-model of a human proximal femur.

Download or read book Perusal of the Finite Element Method written by Radostina Petrova and published by BoD – Books on Demand. This book was released on 2016-12-14 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The finite element method (FEM) is a numerical technique for finding approximate solutions to different numerical problems. The practical applications of FEM are known as finite element analysis (FEA). FEA is a good choice for analyzing problems over complicated domains. The first three chapters of this book contribute to the development of new FE techniques by examining a few key hurdles of the FEM and proposing techniques to mitigate them. The next four chapters focus on the close connection between the development of a new technique and its implementation. Current state-of-the-art software packages for FEA allow the construction, refinement, and optimization of entire designs before manufacturing. This is convincingly demonstrated in the last three chapters of the book with examples from the field of biomechanical engineering. This book presents a current research by highlighting the vitality and potential of the finite elements for the future development of more efficient numerical techniques, new areas of application, and FEA's important role in practical engineering.

This book was released on 2020-01-02 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital models based on data from medical images have recently become widespread in the field of biomechanics. This book summarizes medical imaging techniques and processing procedures, both of which are necessary for creating bone models with finite element methods. Chapter 1 introduces the main principles and the application of the most commonly used medical imaging techniques. Chapter 2 describes the major methods and steps of medical image analysis and processing. Chapter 3 presents a brief review of recent studies on reconstructed finite element bone models, based on medical images. Finally, Chapter 4 reveals the digital results obtained for the main bone sites that have been targeted by finite element modeling in recent years.

Book excerpt: Bone Remodeling Process: Mechanics, Biology, and Numerical Modeling provides a literature review. The first part of the book discusses bones in a normal physiological condition, bringing together the involved actors and factors reported over the past two decades, and the second discusses pathological conditions, highlighting the attack vectors of each bone disease. The third part is devoted to the mathematical descriptions of bone remodeling, formulated to develop models able to provide information that is not amenable to direct measurement, while the last part focuses on models using the finite element method in investigating bone biomechanics. This book creates an overall image of the complex communication network established between the diverse remodeling actors, based on overwhelming control evidence revealed over recent years, as well as visualizes the remodeling defects and possible treatments in each case. It also regroups the models allowing readers to analyze and assess bone mechanical and biological properties. This book details the cellular mechanisms allowing the bone to adapt its microarchitecture to the requirements of the human body, which is the main issue in bone biology and presents the evolution of mathematical modeling used in a bone computer simulation. Each chapter covers a core topic in bone biomechanics Provides a multidisciplinary view that effectively links orthopaedics, cellular biology, mechanics, and computer simulation Draws an overall image about bone biology and cell interactions, for identifying cell populations that are crucial for the remodeling process
