The contents of this book are based almost exclusively on purely anatomical researches. These were stimulated by questions posed in clinical practice. The results are directed to practicing surgeons. Their chronological sequence leads to a step by step development of theoretical bases and to a progressive rejection of old conceptions. Especially in the field of orthopaedic surgery, a responsible attitude is possible neither without solid anatomical knowledge, nor without an idea of functional relationships. W. Roux had already demonstrated this and he wanted his works of functional anatomy to be considered from this point of view. He above all preoccupied himself with a uniform theory of functional adaptation. Thus it is understandable that the theories ofRoux formed the basis from which to start. Our own researches seemed at first to corroborate the ideas of Roux, at least in part. This is still evident in the monograph concerning fractures of the femoral neck. Later it appeared that ST. KROMPECHER had made a step forwards in the matter of chondrogenesis when he abandoned the shear theory postulated by Roux and held that compression was the only effective stimulus for the forma tion of cartilage. The research concerning the healing of fractures relies partly on the theory of KROMPECHER which was new at that time. But ultimately more and more discoveries could no longer be explained by this conception which was only slightly different from the older theories (1. WOLF, W. Roux, W.

The textbook describes the complexity of the human dynamic behavior in space and its ability to produce coordinated, adaptive, dynamically stable movements under steady conditions while negotiating complex terrains and experiencing unexpected perturbations. Applying fundamental theories of biomechanics and physiology, the authors further consider the physical, perceptual, and motor aspects of the locomotor system towards the analysis of how humans can behave adaptively in space by virtue of their intelligent sensory-motor functions and to illuminate our understanding of how this complexity in behavior can provide insight into the neural control of locomotion of the musculoskeletal system. The text provides a foundation for describing the normal and abnormal human locomotor systems. The Human Locomotor System: Physiological and Technological Foundations is intended as a primary text for upper-undergraduate and graduate-level courses in neuroscience, gait analysis, kinesiology, physical therapy, sports science, and biomedical and rehabilitation engineering. It is also a valuable professional reference for scientists and engineers at medical and pharmaceutical companies involved in bioengineering research and development.

Because of developments in powerful computer technology, computational techniques, advances in a wide spectrum of diverse technologies, and other advances coupled with cross disciplinary pursuits between technology and its greatly significant applied implications in human body processes, the field of biomechanics is evolving as a broadly significant area. This Third Volume presents the advances in widely diverse areas with significant implications for human betterment that occur continuously at a high rate. These include dynamics of musculo-skeletal systems; mechanics of hard and soft tissues; mechanics of muscle; mechanics of bone remodeling; mechanics of implant-tissue interfaces; cardiovascular and respiratory biomechanics; mechanics of blood flow, air flow, flow-prosthesis interfaces; mechanics of impact; dynamics of man machine interaction; and numerous other areas. The great breadth and depth of the field of biomechanics on the international scene requires at least four volumes for adequate treatment. These four volumes constitute a well integrated set that can be utilized as individual volumes. They provide a substantively significant and rather comprehensive, in-depth treatment of biomechanic systems and techniques that is most surely unique on the international scene.

Biomechanics aims to explain the mechanics oflife and living. From molecules to organisms, everything must obey the laws of mechanics. Clarification of mechanics clarifies many things. Biomechanics helps us to appreciate life. It sensitizes us to observe nature. It is a tool for design and invention of devices to improve the quality of life. It is a useful tool, a simple tool, a valuable tool, an unavoidable tool. It is a necessary part of biology and engineering. The method of biomechanics is the method of engineering, which consists of observation, experimentation, theorization, validation, and application. To understand any object, we must know its geometry and materials of construc tion, the mechanical properties of the materials involved, the governing natural laws, the mathematical formulation of specific problems and their solutions, and the results of validation. Once understood, one goes on to develop applications. In my plan to present an outline of biomechanics, I followed the engineering approach and used three volumes. In the first volume, Biomechanics: Mechanical Properties of Living Tissues, the geometrical struc ture and the rheological properties of various materials, tissues, and organs are presented. In the second volume, Biodynamics: Circulation, the physiology of blood circulation is analyzed by the engineering method.

Cutting-edge solutions to current problems in orthopedics, supported by modeling and numerical analysis Despite the current successful methods and achievements of good joint implantations, it is essential to further optimize the shape of implants so they may better resist extreme long-term mechanical demands. This book provides the orthopedic, biomechanical, and mathematical basis for the simulation of surgical techniques in orthopedics. It focuses on the numerical modeling of total human joint replacements and simulation of their functions, along with the rigorous biomechanics of human joints and other skeletal parts. The book includes: An introduction to the anatomy and biomechanics of the human skeleton, biomaterials, and problems of alloarthroplasty The definition of selected simulated orthopedic problems Constructions of mathematical model problems of the biomechanics of the human skeleton and its parts Replacement parts of the human skeleton and corresponding mathematical model problems Detailed mathematical analyses of mathematical models based on functional analysis and finite element methods Biomechanical analyses of particular parts of the human skeleton, joints, and corresponding replacements A discussion of the problems of data processing from nuclear magnetic resonance imaging and computer tomography This timely book offers a wealth of information on the current research in this field. The theories presented are applied to specific problems of orthopedics. Numerical results are presented and discussed from both biomechanical and orthopedic points of view and treatment methods are also briefly addressed. Emphasis is placed on the variational approach to the investigated model problems while preserving the orthopedic nature of the investigated problems. The book also presents a study of algorithmic procedures based on these simulation models. This is a highly useful tool for designers, researchers, and manufacturers of joint implants who require the results of suggested experiments to improve existing shapes or to design new shapes. It also benefits graduate students in orthopedics, biomechanics, and applied mathematics.

Biomechanics is often overlooked when dealing with orthopedic injuries, whether regarding prevention or treatment, and practicing surgeons and surgeons-in-training may feel overwhelmed when referring to a book with a more complicated basic science approach. In order to make the subject clinically relevant to orthopedic trauma surgery, this unique text presents numerous clinical case examples to demonstrate clearly and effectively the principles biomechanics of injury, fixation and fracture healing. Divided into five sections, the opening chapters cover the essentials of stress and strain relevant to bone and joints and how this relates to fractures and their healing, complete with illustrative case material. This case-based approach is carried throughout the book, with part two discussing biomechanical principles of external fixation for diaphyseal and periarticular fractures, limb lengthening and deformity correction. Tension band wiring for both olecranon and patella fractures are covered in part three, and both locking and nonlocking plates are illustrated in part four. The final section describes biomechanical principles of intramedullary nails for a variety of fractures and nonunions, as well as arthrodesis and lengthening. Generous radiological images and intraoperative photos provide a helpful visual enhancement for the clinical material. Making the sometimes esoteric topic of biomechanics more clinically relevant to the practicing clinician, Essential Biomechanics for Orthopedic Trauma will be an excellent resource not only for orthopedic surgeons, sports medicine specialists and trauma surgeons, but also medical and biomedical engineering students and residents.

This book addresses instruments, methodologies and diagnostic methods used to evaluate and diagnose human movement, locomotion and physical status in general. Starting from historical perspective, the idea of understanding human locomotion by applying technical measurement devices and incorporating measurement data into physical representation of gross body movement is presented and explained, an approach known as inverse dynamics. With this approach as a kind of umbrella concept, components of measurement systems including relevant signal and data processing methods are described. Modern instruments to capture body movement by measuring its kinematics, kinetics and surface electromyography (sEMG) are thus described; all systems being used dominantly—if not exclusively—in a movement analysis laboratory setting. Focusing mainly on human posture and gait, but including also examples of movement patterns from selected kinesiological and sports activities, the book attempts to present essentials of biomechanics and biomedical engineering approach to this subject matter. It illustrates how data collected and elaborated by modern engineering technology can complement traditional expert knowledge of a kinesiologist or a medical doctor. The book is applicable in the fields of sports, physical activities, as well as in medical diagnostics and rehabilitation. The examples of this book’s practical application might be in evaluation of efficiency of human gait, in evaluation of skeletal muscle fatigue in physical exercise, in biomechanical diagnostics of traumatological conditions requiring orthopaedic treatment and the like. This book can also be used in planning and executing research endeavours, particularly in a clinical context as a reference for various diagnostics procedures. It presents the lecture notes of a course carrying the same name within Medical Studies in English at the University of Zagreb for more than a decade.
