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.

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

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.

Dr. MAQUET, the foremost disciple of Professor PAUWELS' and the orthopae dic heir to the PAUWELS' concepts of osteotomy of the hip for arthritis, has assembled in this one book the strongest and most lucid contemporary statement of the principles and practice of this very important school of hip surgery. Professor PAUWELS' contributions to the understanding of the biomechanics of the hip and to the concepts and execution of osteotomy of the hip for arthritis are outstanding and timeless. With clarity, Dr. MAQUET articulates this position and refines it further in the light of his own investiga tion. While other investigators, of course, differ on individual concepts or princi ples in this book or disagree with specific positions, assumptions, or conclu sions, it is clear to all that this book is a benchmark work. Dr. MAQUET, as Professor PAUWELS always did, illustrates his text lavishly with beautiful examples of individual cases illuminating the principles ad vanced. But in addition, he has gone further and presents long-term follow-up data, quantifying the results of these surgical precepts as experienced in his own practice. It is a work that has been long sought and is richly received. Boston, Massachusetts, 1984 WILLIAM H. HARRIS, M.D.

This book presents analyses of the most commonly reported failure modes of hip stems: loosening and thigh pain; both are attributed to the relative motion and instability at the bone-implant interface due to failure to achieve sufficient primary fixation. The book investigates various factors that could affect primary stability and therefore the long-term outcome of hip arthroplasty. The results complement experimental work carried out in this area as in-vitro experiments have several limitations that could be addressed through computer simulations.

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.
