Available in PDF, EPUB and Kindle. Book excerpt: An osteoporotic fracture occurs approximately every three seconds. Worldwide, this sums to nearly 9 million annual fractures caused by osteoporosis--a systemic, degenerative skeletal disorder that is characterized by low bone mass and increased bone tissue fragility. Although the individual and economic burden of osteoporosis nearly outweighs that of most cancers and many chronic illnesses, the existing methods for treatment are insufficient and many who are at risk remain undiagnosed. To develop improved osteoporosis treatments, prevent osteoporotic fractures, and promote bone health throughout the aging process, it is imperative to understand bone biomechanical behavior and the factors contributing to bone mechanotransduction and adaptation. Consequently, the first objective for the presented research was to characterize the effects and interactions of mechanical stimulus and biochemical signaling activity on the modeling and remodeling response of bovine and human trabecular bone through the use of ex vivo organ culture. The second objective for the research was to simulate the mechanical behavior and dynamic remodeling response of bone tissue through the use of finite element analyses and analytical cell population models. Collectively, the presented research illustrated that bone modeling and remodeling can be affected by the amount and type of applied mechanical stimulus and biochemical exposure. In addition, the research showed that, despite current limitations, simulation and prediction of bone response to applied stimulus is feasible with additional development of existing models.

Book excerpt: This book focuses on the structure of bone, and its consequences for the mechanical behaviour of the bone structure. The first part of this book focuses on the development of models to predict the adaptation of bone due to changes on the mechanical loading situation (such as provoked by an implant). But far more important than the computer power presently available, the incorporation of knowledge on the biological processes have led to new kinds of models. Next to the development of models itself, the issue of model validation though comparison with clinical data is a main issue addressed in the papers of this symposium. The second part, dealing with the relationship between bone architecture and competence of bone, focuses on the morphology of trabecular bone structure. This work is mainly carried out in the context of research on osteoporosis, and look for the relation between bone structure and fracture risk. The last part is devoted to ultrasound research in bone biomechanics. Several methods have been described for the in vitro and in vivo measurement of ultrasound velocity and attenuation, both on cortical and on trabecular bone. The reader will not only discover the state-of-the-art when reading though this book. This book can give a taste of the fascinating perspectives the research in bone biomechanics still have to offer, even after more than 100 years.
Download or read book Animal Experiment rabbit to Demonstrate Changes in Trabecular Bone Mechanical Properties Over Time Using Finite Element Analysis written by Shuo Yang and published by . This book was released on 2006 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear heterogeneous finite element analysis was used to calculate trabecular bone apparent strength directly from in vivo micro computational tomography (micro-CT) scans. Through a series of validation experiments, it was shown that this nonlinear modeling is more accurate in evaluating trabecular bone mechanics in osteoporosis than previous work. A parameter driven set of material properties was employed in the finite element models using gray levels in the form of Hounsfield units as the independent variable. This enabled the finite element models to capture the variations of material properties of trabecular bone. The methods and techniques for converting the micro-CT scans into finite element models, defining the finite element models (element type, material properties characteristics) and solving the models are discussed in detail. In addition, the techniques developed for image preprocessing, such as image registration and image degradation, are also provided in this dissertation.

Download or read book Osteoporosis written by Benjamin Z. Leder and published by Springer Nature. This book was released on 2020-01-31 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Completely revised and updated, and utilizing the most current evidence and practice guidelines for the treatment of osteoporosis, this comprehensive third edition discusses the basic aspects of bone metabolism, the pathophysiology of osteoporosis, current diagnostic techniques and medical treatment strategies. Osteoporosis is a common disorder that is prevalent in over 20 million Americans over the age of 60. One and a half million osteoporotic fractures occur in the United States every year, including 300,000 hip fractures. Mortality rates after hip fracture approach 25%, with another 50% of patients experiencing a major decrease in their prior level of independence and quality of life. Despite the wide prevalence and severe consequences of osteoporosis, it remains a disorder that is severely under-diagnosed and treated. In this context, specialists and primary care physicians alike are having increasing difficulty keeping up with the rapid changes to the field and incorporating these advances to clinical care. In the years since the last edition of this book was published, the osteoporosis field has changed drastically. In addition to revising and updating existing chapters and removing a few that are no longer as relevant, new chapters discuss an advanced understanding of the cellular and molecular mechanisms underlying the disorder, the introduction of new diagnostic imaging techniques, a more nuanced appreciation of the risks and benefits of osteoporosis therapies, and the introduction of two new classes of osteoporosis medications. Following the format of the second edition, and including helpful key points at the opening of each chapter, this text will present a comprehensive overview of both the basic and clinical concepts relating to each topic, when appropriate. Chapter authors were chosen based on their high level of expertise and leadership in the field. Taken together, this text should thus be of great interest to physicians of multiple specialties, allied health professionals, as well as basic and clinical researchers.

Download or read book Noninvasive Assessment of Trabecular Bone Architecture and The Competence of Bone written by Sharmila Majumdar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of bone microarchitecture is flourishing because of a recent shift in perspective that has taken researchers beyond utilizing bone mineral density as the primary source of information about certain matters related to bone. In the area of osteoporosis and skeletal changes, bone mineral density (BMD) is widely used for screening, monitoring and assessing therapeutic efficacy, and yet, it is currently accepted that BMD does not fully explain the pathogenesis of osteoporosis, the process of aging, nor mechanisms of therapeutic efficacy. In this context, the study of trabecular microarchitecture has much to contribute. The emerging field of trabecular microarchitecture, however, is diverse, inter-disciplinary and encompasses many different imaging modalities. This volume represents a compilation of papers from world-renowned researchers, reflecting the most current research in the area of noninvasive assessment of trabecular microcarchitecture. This varied research applies sophisticated imaging tools to questions of bone biomechanics at both the basic science and clinical levels. The authors' works range from review articles and research articles to works in progress. Taken together, they offer a foray into the "state of the art" of investigating bone at its most basic levels.

Download or read book Uncertainty in Biology written by Liesbet Geris and published by Springer. This book was released on 2015-10-26 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational modeling allows to reduce, refine and replace animal experimentation as well as to translate findings obtained in these experiments to the human background. However these biomedical problems are inherently complex with a myriad of influencing factors, which strongly complicates the model building and validation process. This book wants to address four main issues related to the building and validation of computational models of biomedical processes: 1. Modeling establishment under uncertainty 2. Model selection and parameter fitting 3. Sensitivity analysis and model adaptation 4. Model predictions under uncertainty In each of the abovementioned areas, the book discusses a number of key-techniques by means of a general theoretical description followed by one or more practical examples. This book is intended for graduate students and researchers active in the field of computational modeling of biomedical processes who seek to acquaint themselves with the different ways in which to study the parameter space of their model as well as its overall behavior.
