This volume is the arranged monograph based on the Hip Biomechanics Symposium held on November 1992 in Fukui, Japan. It consists of six major sections: loading, gait analysis, total hip arthroplasty, osteotomies, motion analysis, and stem designs for stability. The most important aim of the volume is to overview the current research outcomes in the biomechanical approaches to adult hip diseases. Each of these sections brings together many of the leading researchers in this field. The information found here will be of benefit to orthopedic surgeons and researchers in the related areas.

Orthopaedic surgery today is undergoing a phase of vara, pseudarthrosis of the neck of the femur, and osteo turbulent development. Once the essential aim of treatment arthritis, even in cases which up to now would usually have been considered incurable. consisted in restitution of anatomy by surgery in order to This atlas not only shows convincing results of such restore function. Various forms of alloplasty have recently become fashionable for the treatment of joint diseases. treatment. Above all, it gives interested clinicians a line to The main reason for this vogue is that restoration of follow and sets out precise indications for the practical normal anatomy improves function and alleviates pain steps of the operations. only in certain special instances. I am especially grateful to Professor B. Kummer who, as Alternatively, the implantation of artificial joints of an anatomist, acted as the devil's advocate, and subjected different types has been presented as the method of the new concepts in functional anatomy and biomechanics choice because the immediate results are often spectacular shown in the atlas to critical analysis.

This open access book describes and illustrates the surgical techniques, implants, and technologies used for the purpose of personalized implantation of hip and knee components. This new and flourishing treatment philosophy offers important benefits over conventional systematic techniques, including component positioning appropriate to individual anatomy, improved surgical reproducibility and prosthetic performance, and a reduction in complications. The techniques described in the book aim to reproduce patients’ native anatomy and physiological joint laxity, thereby improving the prosthetic hip/knee kinematics and functional outcomes in the quest of the forgotten joint. They include kinematically aligned total knee/total hip arthroplasty, partial knee replacement, and hip resurfacing. The relevance of available and emerging technological tools for these personalized approaches is also explained, with coverage of, for example, robotics, computer-assisted surgery, and augmented reality. Contributions from surgeons who are considered world leaders in diverse fields of this novel surgical philosophy make this open access book will invaluable to a wide readership, from trainees at all levels to consultants practicing lower limb surgery

The field of hip preservation surgery has evolved over the past decade as our understanding of hip pathomechanics and pathomorphology has expanded. The published literature on non-arthritic hip pathology, for example, has grown exponentially. The topics of controversy in the past decade have been answered in some cases, but new questions have also arisen. In addition to the 99 chapters in the original edition – most of which will be retained and updated as applicable – there will be over 30 brand new chapters focusing on new and more sophisticated techniques from authors that have been the pioneers of the field. The text is divided into nine thematic sections, covering the breadth of the topic and the current state of the art: basic science of the hip; operative basics for hip arthroscopy and open hip preservation surgery; pediatric hip conditions; approaches to disorders of the hip and pelvis; enthesopathy and neuromuscular disorders; hip fractures and instability; avascular necrosis; hip cartilage restoration; and oncologic conditions. Throughout, there is a heavy emphasis on surgical techniques, and video clips will be included in selected chapters. Written by edited by thought leaders and seasoned practitioners in the field, this new edition of Hip Arthroscopy and Hip Joint Preservation Surgery will remain the gold standard for orthopedic surgeons and sports medicine specialists, expanding on the range of techniques available to clinicians treating injuries to and disorders of the hip.

This book represents the most advanced understanding of diagnosis and management of hip dysplasia in the young adult, written by the world’s leading experts and covering advanced imaging and biomechanical studies as well as latest surgical techniques. This is especially timely, as the field of hip preservation surgery is in constant evolution, and it is critical that surgeons and researchers combine their efforts to provide the best evidence-based knowledge to all health care providers evaluating and treating patients suffering from pre-arthritic hip pain. Not only does this book discuss the most up-to-date information on the etiology and natural history of hip dysplasia, as well as pathomechanics and traditional and advanced imaging, it also presents new conceptions of its classification and subsequent management. The focus throughout the book is that hip dysplasia is a problem of instability, where both the bony structure and the soft tissue envelope (i.e., capsule, ligaments and muscles) are at play. Moreover, although corrective osteotomies such as the peri-acetabular osteotomy will remain the dominant treatment option, non-surgical treatments as well as hip arthroscopy are now being increasingly recognized as useful adjuncts in order for our patients to return to their desired activities. Finally, as the longevity of joint replacement surgery has improved dramatically, this should be strongly considered in cases where the outcome of joint preserving surgery is not as predictable. Orthopedic surgeons, sports medicine physicians, physiatrists and physiotherapists alike will find this book a valuable resource when treating the young adult with symptomatic hip dysplasia.

This book provides state-of-the-art and up-to-date discussions on the pathology-related considerations and implications in the field of orthopaedic biomechanics. It presents fundamental engineering and mechanical theories concerning the biomechanics of orthopaedic and anatomical structures, and explores the biological and mechanical features that influence or modify the biomechanics of these structures. It also addresses clinically relevant biomechanical issues with a focus on diagnosis, injury, prevention and treatment. The first 12 chapters of the book provide a detailed review of the principles of orthopaedic biomechanics in the musculoskeletal system, including cartilage, bone, muscles and tendon, ligament, and multiple joints. Each chapter also covers important biomechanical concepts relevant to surgical and clinical practice. The remaining chapters examines clinically relevant trauma and injury challenges in the field, including diagnostic techniques such as movement analysis and rehabilitation intervention. Lastly it describes advanced considerations and approaches for fracture fixation, implant design, and biomaterials.

This book presents a fundamental basic overview of orthopedic biomechanics in sports medicine, with a special focus on the current methodologies used in modeling human joints, ligaments, and muscle forces. The first part discusses the principles and materials, including the use of finite element analysis (FEA) to analyze the stress-strain response in the implant-bone interface and design. The second part focuses on joint-specific biomechanics, highlighting the biomechanics of the knee and shoulder joints, their modeling, surgical techniques, and the clinical assessment of joint performance under various kinematic conditions resulting from different repair techniques. Written by international experts working at the cutting edge of their fields, this book is an easy-to-read guide to the fundamentals of biomechanics. It also offers a source of reference for readers wanting to explore new research topics, and is a valuable tool for orthopedic surgeons, residents, and medical students with an interest in orthopedic biomechanics.​

Orthopaedic surgeons require not only an understanding of anatomy and clinical sciences, and competence in surgical skills, but also a strong foundation in biomechanics. The application of biomechanics plays an increasing role in modern orthopaedics; for example, correct decisions about the mode of treatment and choice of implants are just as important as operating precisely to reach a specific anatomical landmark. This book simplifies the core principles in orthopaedic biomechanics, giving readers the solid grounding they need to flourish in the specialty. Each topic is covered in a discrete, double-page spread, featuring concise text accompanied by illustrations or tables to give readers a solid understanding of the concepts discussed. This is a must-read guide for orthopaedic trainees at every level, and will be valuable for biomechanical researchers and other professionals in the field.

This book provides an evidence-based approach to treating the increasing number of children and adolescents presenting with hip disorders. It integrates the most up-to-date data with essential knowledge, gleaned from decades of previous research and practice. Each chapter provides a comprehensive text which integrates relevant pathophysiology, clinical assessment, and imaging, with an evidence-based approach to non-operative and operative management, authored by globally recognized experts in the field of pediatric hip surgery. Detailed surgical techniques, illustrated with original medical drawings and accompanied by their respective indications, anticipated outcomes, and potential complications, are also featured, in this first orthopedic text dedicated solely to the pediatric and adolescent hip. The Paediatric and Adolescent Hip: Essentials and Evidence will be an indispensable resource for wide spectrum of audience including paediatric orthopaedic surgeons, general practitioners, general orthopaedic surgeons, trauma surgeons, orthopaedic residents, emergency department doctors, and physiotherapists seeking a clear and consistent evidence-based guide to treating the paediatric hip.

Pathological conditions affecting the hip and knee joints occupy a particular place amongst the important orthopaedic entities affecting the extremities. On the one hand they are relatively frequent and on the other they mean for the patient limitation of his ability to walk, because of their considerably detrimental effects. A purposeful basic treatment of these joint diseases (and here osteoarthritis takes pride of place) is only possible if it stems from a reliable biomechanical analysis of the normal and patho logical stressing of the joint in question. Whilst the situation in the hip can be considered to be fundamentally clarified, a com prehensive representation of the knee is still lacking particularly when taking into account the latest knowledge of biomechanics. Recently our concepts of the kinematics of the knee have been completely changed, but the clinically important question of articular stressing remains unanswered. Dr. Maquet has carried out pioneer work in this field for some years in adapting, by analogy, to the knee joint, principles already accepted for the hip joint. Since the knee is not a ball and socket joint, a complicated problem arises for which new thoughts are necessary. The results of the numerous operations carried out by Dr. Maquet according to the biomechanical con siderations, demonstrate that his thinking is fundamentally correct. Above all, it is here again proven (as earlier in the case of the hip) that healing of osteoarthritis depends decisively on reducing and evenly distributing joint pressure.
