Book Description
CETTE ETUDE REPOSE SUR LA DEFINITION GEOMETRIQUE DE DIVERSES FACETTES ARTICULAIRES DE L'ASTRAGALE ET DE LEURS VIS-A-VIS SUR LES AUTRES OS. DEUX METHODES D'INVESTIGATION ONT ETE UTILISEES. L'UNE CONCERNE UNE ACQUISITION DES DONNEES PAR METROLOGIE SUR 11 OS SECS, L'AUTRE PROPOSE UNE EXPLOITATION DE CLICHES SCANNER DE 8 PIEDS. LA DEMARCHE SE RESUME EN TROIS ETAPES : L'EMISSION D'UNE HYPOTHESE SUR LA FORME DES SURFACES (CYLINDRES, SPHERES, CONES), LE RELEVE TRIDIMENSIONNEL DE LA SURFACE REELLE, LA DETERMINATION DES DIMENSIONS ET POSITIONS DE CELLE-CI AVEC VALIDATION DE L'HYPOTHESE PAR EVALUATION DES ECARTS DIMENSIONNELS ENTRE SURFACES THEORIQUE ET REELLE. LES RESULTATS SONT SATISFAISANTS ET NOUS PERMETTENT DE CONSTRUIRE UN MODELE CINEMATIQUE THEORIQUE QUI COMPREND PLUSIEURS LIAISONS SIMPLES. LEUR COMPOSITION CONDUIT A UN MODELE CINEMATIQUE COMPLEXE, UTILISABLE MOYENNANT QUELQUES HYPOTHESES. LES DIFFERENTES TRAJECTOIRES ET LES VITESSES DE POINTS CARACTERISTIQUES SONT CALCULEES EN FONCTION DES PARAMETRES GENERATEURS QUE SONT LA POSITION ET LA VITESSE ANGULAIRE DU TIBIA PAR RAPPORT A L'ASTRAGALE DANS UN PLAN SAGITTAL. LES VALEURS DE DEPLACEMENT OBTENUES SONT COHERENTES AVEC LES DONNEES COLLECTEES DANS DES ETUDES ANATOMIQUES ULTERIEURES. UNE ETUDE DYNAMIQUE LOCALE PERMET LE CALCUL DES EFFORTS DANS L'ARTICULATION TIBIO-TARSIENNE EN MODELISANT LES ACTIONS : MUSCULAIRES, LIGAMENTAIRES ET AU SOL. UNE ETUDE PLUS GLOBALE SUR L'ENSEMBLE DU PIED EST MENEE A L'AIDE D'UN LOGICIEL DE SIMULATION DYNAMIQUE. LES EFFORTS OBTENUS SONT SIMILAIRES AUX RESULTATS FOUMIS DANS DIVERSES RECHERCHES DEJA PUBLIEES. A LA SUITE DE L'ETUDE BIOMECANIQUE DU COMPLEXE ARTICULAIRE, NOUS AVONS CONCU, SUR LES BASES GEOMETRIQUES ET CINEMATIQUES, UN IMPLANT COMPATIBLE AVEC L'ENSEMBLE DES MOUVEMENTS OBSERVES. UNE ETUDE DE L'INTERFACE OS-IMPLANT A ETE MENEE GRACE A UNE MODELISATION PAR ELEMENTS FINIS, ORIENTANT NOS CHOIX TECHNOLOGIQUES. UNE PRE-ETUDE DE L'IMPLANTATION DU MATERIEL ET DE SA FABRICATION CONCLUT CES TRAVAUX.

Book Description
The ACL or anterior cruciate ligament is the most important ligament in the knee. When it is completely torn, it can lead to instability or buckling of the knee. There are several options to choose from when selecting a graft for ACL reconstruction such as using autografts including patellar tendon, hamstring tendon, and quadriceps tendon, and allografts (also known as donor tissue or cadaver tissue). Artificial ligaments are also discussed since they are still used in Europe and Asia. This book summarizes the pros and cons of each graft option in detail.

Book Description
Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.

Book Description
Instrumented gait analysis systems offer objective evaluation of the effectiveness of the various rehabilitation treatments that are aimed at improving gait disabilities. There are four sections in this report: clinical observation; review of the instrumental gait analysis systems; the value of information resulting from instrumented gait analysis from the perspective of a psychiatrist, an orthopedic surgeon, & a physical therapist; & discussion of future trends for gait laboratories. The authors are experts from multiple rehabilitation specialties to give you an understanding of how gait analysis can be used to evaluate a person's walking abilities to maximize function & maintain or improve quality of life.

Book Description
With the constant evolution of implant technology, and improvement in the production of allograft and bone substitutes, the armamentarium of the orthopaedic surgeon has significantly expanded. In particular, the recent involvement of nanotechnologies opens up the possibilities of new approaches in the interactive interfaces of implants. With many important developments occurring since the first edition of this well-received book, this updated resource informs orthopaedic practitioners on a wide range of biomechanical advances in one complete reference guide. Biomechanics and Biomaterials in Orthopedics, 2nd edition compiles the most prominent work in the discipline to offer newly-qualified orthopedic surgeons a summary of the fundamental skills that they will need to apply in their day-to-day work, while also updating the knowledge of experienced surgeons. This book covers both basic concepts concerning biomaterials and biomechanics as well as their clinical application and the experience from everyday practical use. This book will be of great value to specialists in orthopedics and traumatology, while also providing an important basis for graduate and postgraduate learning.

Book Description
DHM and Posturography explores the body of knowledge and state-of-the-art in digital human modeling, along with its application in ergonomics and posturography. The book provides an industry first introductory and practitioner focused overview of human simulation tools, with detailed chapters describing elements of posture, postural interactions, and fields of application. Thus, DHM tools and a specific scientific/practical problem – the study of posture – are linked in a coherent framework. In addition, sections show how DHM interfaces with the most common physical devices for posture analysis. Case studies provide the applied knowledge necessary for practitioners to make informed decisions. Digital Human Modelling is the science of representing humans with their physical properties, characteristics and behaviors in computerized, virtual models. These models can be used standalone, or integrated with other computerized object design systems, to design or study designs, workplaces or products in their relationship with humans. - Presents an introductory, up-to-date overview and introduction to all industrially relevant DHM systems that will enable users on trialing, procurement decisions and initial applications - Includes user-level examples and case studies of DHM application in various industrial fields - Provides a structured and posturography focused compendium that is easy to access, read and understand

Book Description
In our increasingly active society, children, teenagers, adults, and the elderly are swimming, jogging, weight training, and competing in a wide variety of individual and team sports. Approximately 85-95% of athletic problems are handled by primary care providers, many of whom are serving as team or school doctors. Sports Medicine for the Primary Care Physician, Second Edition, provides the latest information on major topics in sports science and clinical medicine that affect primary care physicians. The first section of the book presents the history of sports medicine, the role of the primary care doctor in sports, and the scientific ingredients of good athletic care (e.g., pre-participation exam, drugs/doping, prevention and protective equipment, nutrition). The second section considers the nonoperative management of common sports injuries. After an introduction in which epidemiological, rehabilitative, and healing concerns are presented, on-field emergencies and their management are discussed. General and individual sport injuries are detailed in a cohesive, consistent format that includes relevant anatomy; epidemiology; common eponyms; mechanism of injury; history; physical, laboratory, and radiological findings; differential diagnosis; treatment; rehabilitation; consultation guidelines; and prognosis and prevention. Chapter bibliographies provide general and specific references for additional information. Appendices include pertinent sports curricula for professionals involved in athletic care, equipment lists, ACSM position statements, sports jargon compendium, and a detailed guide to common stretching/rehabilitative exercises. The book contains 259 illustrations and 98 tables.
