This book was released on 2008-08-18 with total page 111 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, 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 2019-12-06 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.
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.
Download or read book Retrieval Analysis and Finite Element Modeling of Orthopaedic Porous Coated Implants written by Josa Ann Hanzlik and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Nationwide Inpatient Sample (NIS) studies have shown that implant loosening remains one of the common reasons for revision in total joint replacement. In an effort to reduce loosening caused by long-term breakdown of the cement mantle, manufacturers introduced cementless technologies to provide biological fixation by hard tissue ingrowth at the bone-implant interface. One new material, porous tantalum, has had promising clinical results with well-fixed implants and relatively few reported cases of loosening. The factors that may be causing the lower incidence of aseptic loosening remain unknown. Therefore, the goal of this dissertation was to investigate the factors affecting bone fixation in porous tantalum implants through retrieval analysis and finite element (FE) modeling. Through the Implant Research Center0́9s retrieval program, the proportion of implants revised for aseptic loosening was compared between the porous tantalum implants and historical porous-coated implants. Retrieval analysis protocols were developed to assess and determine factors that affect bone ingrowth in porous tantalum hip and knee implants. Porous tantalum tibial trays were histologically analyzed to determine locations of fibrous tissue or bone ingrowth. The results showed that the amount of bone observed varied by implant type and location within each implant for retrieved porous tantalum acetabular shells, femoral stems, patellas and tibial trays. Retrieval results showed that modular tibial tray implants had higher bone ingrowth than the monoblock tibial trays. However, the bone ingrowth in the porous tantalum was lower than that observed in historical porous-coated implants. Histological analyses of tibial trays demonstrated bone ingrowth primarily in the superficial depth of the tibial trays, with fibrous tissue also present. The FE models showed that there was more favorable initial implant stability in the modular tibial tray compared to the monoblock implant. This study showed that the lower incidence of aseptic loosening did not appear to be associated with increased bone ingrowth for the retrieved porous tantalum hip and knee implants. Initial FE models showed that lower micromotion for the modular tibial tray compared the monoblock. This dissertation presents a multifaceted approach for analysis of highly porous biomaterials.

This book was released on 2013-09-19 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents analyses of the most commonly reported failure modes of hip stems: loosening and thigh pain; both are attributed to the relative motion and instability at the bone-implant interface due to failure to achieve sufficient primary fixation. The book investigates various factors that could affect primary stability and therefore the long-term outcome of hip arthroplasty. The results complement experimental work carried out in this area as in-vitro experiments have several limitations that could be addressed through computer simulations.
