Anterior cervical disc fusion (ACDF) has been a treatment for degenerative disc disease for the last 50 years. ACDF, with a success rate of 95 percent, has been established as the primary method for treating disc disease. However, the fusion approach eliminates motion, which is philosophically different from technologies developed to treat other articulating joints. Subsequently, ACDF is believed to accelerate degeneration in spinal motion segments adjacent to the treated level and lead to cascading failures of the nearby discs. The desire to eliminate such cascading failures has prompted the development of an articulating cervical disc implant (ACDI). The objective of this research was to compare the mechanical behavior of a cervical spine specimen following ACDI with the mechanical behavior of the same specimen following ACDF. A mechanical testing device was developed to induce a controlled, pure moment loading scheme and to facilitate near physiological flexion-extension motion. The measures used to quantify the comparison were global kinematics, segmental kinematics, and intradiscal pressures. This study concluded the performance of the ACDI was at least equivalent to ACDF. Furthermore, this study suggested the ACDI promoted more energy absorption within the cervical spine and transferred less stress to adjacent discs at higher loads than the ACDF, but more tests are required to increase our confidence in this interesting possibility.

Human intervertebral disc replacement is quickly becoming a superior substitute for cervical disc fusion as a surgical treatment for degenerative disc disease. The current disc implants share similar materials and show significant improvements over past designs. Scientific studies continue to evaluate the results of the implants compared to fusion, with the primary focus placed on the preservation of normal spine biomechanics with the articulating abilities of the implant versus absence of motion with fusion. This thesis investigated the biomechanical effects on the spine with eccentricity of the implant. More specifically, implantation at a location that is laterally offset from the midsagital axis, thus yielding misalignment to the patient's left or right from the geometric vertical axis. This study concentrates on the three main joints in the cervical spine and the load distribution on them due to a static axial loading case only. Three separate evaluations were used to compare results. A mechanical testing apparatus that simulates eccentric implantation was designed, built, and tested. Numerical and mathematical models of this apparatus completed the trio of evaluations. The results showed a characteristic that is linear. That is, minor offsets in the order of millimeters demonstrate significant increases in static loads on the facet furthest from the implant. A consideration of these results and research suggests that this could be the cause of long-term facet degeneration. The conclusion of this thesis suggests future research is needed to further understand this phenomenon, improve the surgical technique, or improve the implant, all in order to either better understand the biomechanical sacrifices with eccentric implantation or eliminate it all together.

Top Experts Share Clinical Insights on Biological Interventions for Spine-Related Disease Although there have been significant advancements in minimally invasive spinal surgery techniques in the last few decades, optimal outcomes for chronic low back pain remain elusive. A number of promising clinical trials have been conducted using tissue engineering and biological interventions for disc degeneration. Written by renowned innovators, this is the first book that covers implementation of these groundbreaking approaches for disc disease. The text begins with key fundamentals including anatomy and physiology, pathophysiology, imaging and biomechanics to delineate healthy versus diseased spine. Subsequent sections discuss treatment strategies, research findings, and future developments. Throughout each chapter, renowned spine surgeons and scientists share clinical pearls gleaned from hands-on experience. Key Highlights The current state of the art in biological and tissue engineering procedures for spinal disorders Treatment methodologies including nucleus replacement and repair, annulus fibrosus repair, total disc transplantation, and mechanical total disc replacement Innovative treatment strategies for disc regeneration, such as genes and proteins Growth factors including platelet-rich plasma (PRP), which has shown promise for the stimulation and acceleration of bone and soft tissue healing Cell-based therapy for spinal disc regeneration and repair including the use of stem cells and chondrocytes In-depth discussion of research including animal versus human model, in-vitro, and a summary of biologic clinical trials This is a must-have resource for trainee and practicing orthopaedic surgeons and neurosurgeons who treat patients for spine-related conditions. It is essential reading for all clinicians who have an interest in cutting-edge tissue engineering and biological treatment interventions.

Biomechanics of the Spine encompasses the basics of spine biomechanics, spinal tissues, spinal disorders and treatment methods. Organized into four parts, the first chapters explore the functional anatomy of the spine, with special emphasis on aspects which are biomechanically relevant and quite often neglected in clinical literature. The second part describes the mechanics of the individual spinal tissues, along with commonly used testing set-ups and the constitutive models used to represent them in mathematical studies. The third part covers in detail the current methods which are used in spine research: experimental testing, numerical simulation and in vivo studies (imaging and motion analysis). The last part covers the biomechanical aspects of spinal pathologies and their surgical treatment. This valuable reference is ideal for bioengineers who are involved in spine biomechanics, and spinal surgeons who are looking to broaden their biomechanical knowledge base. The contributors to this book are from the leading institutions in the world that are researching spine biomechanics. Includes broad coverage of spine disorders and surgery with a biomechanical focus Summarizes state-of-the-art and cutting-edge research in the field of spine biomechanics Discusses a variety of methods, including In vivo and In vitro testing, and finite element and musculoskeletal modeling

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.
