Download or read book The Intervertebral Disc written by Irving M. Shapiro and published by Springer Science & Business Media. This book was released on 2013-09-02 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intervertebral disc is a complex structure that separates opposing vertebrae, permits a wide range of motion, and accommodates high biomechanical forces. Disc degeneration leads to a loss of function and is often associated with excruciating pain. Written by leading scientists and clinicians, the first part of the book provides a review of the basic biology of the disc in health and disease. The second part considers strategies to mitigate the effects of disc degeneration and discusses the possibility of engineering replacement tissues. The final section is devoted to approaches to model normal development and elucidate the pathogenesis of degenerative disc disease using animal, organ and cell culture techniques. The book bridges the gap between the basic and clinical sciences; the target audience includes basic scientists, orthopaedists and neurologists, while at the same time appealing to the needs of graduate students, medical students, interns and fellows.
Download or read book Mechanical Analogue Model of the Human Lumbar Spine written by CD. Pence and published by . This book was released on 2003 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical testing of spinal instrumentation on cadaveric spine segments can be challenging. In this study, a mechanical analogue lumbar spine model was developed to be similar in rigidity to that of cadaveric spine segments. Three models of an adult human lumbar spine were built from composite vertebrae, ligaments and discs created individually to reproduce the nonlinear mechanical properties of human components. These models and three calf lumbar spines were loaded in a biaxial mechanical test system in axial compression, torsion, right and left lateral bending, flexion and extension. Rigidities were calculated in the secondary linear load-displacement region. Load-displacement behavior was nonlinear for both analogue and calf spines. There was good reproducibility between the models. Average axial rigidity of the analogue spines was 86 N/mm versus 231 N/mm for the calf spines, possibly due to the calf flat-back. In the remaining loading modes, the analogue spine was 26-65% more rigid than young calf spines. Comparisons to human cadaveric spine segments are underway.

Available in PDF, EPUB and Kindle. Book excerpt: The picture on the front cover of this book depicts a young man pulling a fishnet, a task of practical relevance for many centuries. It is a complex task, involving load transmission throughout the body, intricate balance, and eye head-hand coordination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable pertur bations, has a long history. However, despite a history of magnificent sculptures and drawings of the human body which vividly depict muscle ac tivity and interaction, until more recent times our state of knowledge of human movement was rather primitive. During the past century this has changed; we now have developed a considerable database regarding the com position and basic properties of muscle and nerve tissue and the basic causal relations between neural function and biomechanical movement. Over the last few decades we have also seen an increased appreciation of the impor tance of musculoskeletal biomechanics: the neuromotor system must control movement within a world governed by mechanical laws. We have now col lected quantitative data for a wealth of human movements. Our capacity to understand the data we collect has been enhanced by our continually evolving modeling capabilities and by the availability of computational power. What have we learned? This book is designed to help synthesize our current knowledge regarding the role of muscles in human movement. The study of human movement is not a mature discipline.
Download or read book The Passive Load bearing Capacity of the Human Lumbar Spine in the Neutral Standing Posture written by Shaun B. Jeffs and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel method of applying physiologic loads to the lumbar spine in vitro to determine its passive stability was developed. Five cadaver specimens were tested and a passive equilibrium posture was discovered for each. Further, the parameters defining the equilibrium posture correlate well with the standing posture as reported in the literature. This is an indication that the lumbar spine is inherently capable of remaining erect in the neutral posture with muscle activations below 5% MVC. It is postulated that the iliolumbar ligament and the thoracolumbar fascia, passive components that are not typically incorporated into stability models of the spine, have the potential to provide added passive stabilization to the system. It is recommended that biomechanical models of the spine incorporate this 5% MVC constraint and place greater emphasis on the contributions of passive structures to overall stability.

Download or read book Sagittal Balance of the Spine written by Pierre Roussouly and published by Thieme. This book was released on 2019-07-25 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unique resource from internationally renowned experts details the key role of sagittal spine balance Through evolution, human verticality became associated with a wide range of normal pelvic shapes and associated pelvic incidence angles (PIs). While all types of sagittal alignment generally provide adequate support to young adults, age, stress, and related degeneration can progressively lead to sagittal imbalance and contribute to various spinal pathologies. Sagittal Balance of the Spine by Pierre Roussouly, João Luiz Pinheiro-Franco, Hubert Labelle, Martin Gehrchen, and a cadre of esteemed international contributors focuses on the importance of sagittal alignment and spino-pelvic shape identification in clinical practice. Offering the most comprehensive text on sagittal balance to date, this state-of-the-art, richly illustrated book fills a void in the literature, offering clinical pearls throughout seven sections and 24 chapters. Key Highlights The biomechanics of sagittal balance including spine modeling, primary parameters, spinal curves segmentation, and lumbar lordosis classification The role of sagittal balance in low back pain and degeneration, with discussion of spinal orientation and the contact forces theory, spinal degeneration associated with spinopelvic morphotypes, and compensatory mechanisms Comprehensive analysis of the relationship between sagittal imbalance and isthmic lysis spondylolisthesis, degenerative spondylolisthesis, Scheuermann's kyphosis, adolescent idiopathic scoliosis, and adult scoliosis Posterior and anterior treatment approaches – from spinal fixation and spinal fusion – to spinal osteotomy techniques and management of surgical failure This text is essential reading for every neurosurgical and orthopaedic resident, as well as veteran surgeons who evaluate and treat patients with spine conditions. Clinicians will learn why incorporating sagittal balance evaluations into spinal exams is integral to devising more effective treatment strategies and achieving improved outcomes.

Download or read book Musculoskeletal Disorders and the Workplace written by Institute of Medicine and published by National Academies Press. This book was released on 2001-05-24 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.
