Available in PDF, EPUB and Kindle. Book excerpt: The effects of medicaments, used in the treatment of arthritic diseases, on the surface tension of the synovial fluid have been measured. The synovial fluid was obtained from the carpal joints of freshly slaughtered 'calves and from knee joints of arthritic patients. Values obtained for the surface tension (~) of the pure liquids were 47. 6 mN/m and 45. 8 mN/m respectively. The surf£ce tensions of the additives and their effect, as a function of concentration, on the surface tension of synovial fluid are shown in figure 2. From this diagram it can be seen that bone and cartilage extract(K u. K-

Available in PDF, EPUB and Kindle. Book excerpt: Organ transplantation has almost disappeared from headlines in the daily press, possibly because it failed to fulfill exaggerated expectations. Transplanta tion pathology has become more and more important, not only with relation to therapeutic transplantations but even more in its fundamental theories. There is some analogy here to the development in space science where spectacular achievements were followed by sobering frustrations and where, for the time being, the effect on technology is more fruitful than the outcome of the original far-reaching projects. That transplant rejection was defined, in most of its stages, as an immunologic process, has given many new impulses to immunology in general. Transplantation assays have become a pet experiment in immunobiology and an abundant source of general information and knowledge. The implications of such a development could not be predicted when the present volume was outlined and planned. In accordance with the concept of WILLI MASSHOFF, general transplantion pathology was given a central position as a fundamental science, while the chapters on the transplantation of various tissues are of a more paradigmatic character. It was MASSHOFF who invited competent authors and who managed to balance their articles, despite some overlapping, so as to draw a comprehensive picture of contemporary transplanta tion pathology. WILLI MASSHOFF died while he was editing the first manuscripts. As co-editors we have undertaken to complete the publication that we began together.

Download or read book Effects of Joint Incongruity on Articular Pressure Distribution and Subchondral Bone Remodeling written by F. Eckstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the present work is to review the existing literature on joint incongruity, cellular mechano-transduction, and computer simulations of mechano-adaptive bone remodelling, and to quantitatively assess the effect of incongruity on load transmission and subchondral mineralisation. Idealised computer models of incongruous joints and a specific anatomically based model of the humero-ulnar joint articulation were analysed with the finite element method, and the results directly compared with experimental and morphological data.

Download or read book Advances in Artificial Hip and Knee Joint Technology written by M. Schaldach and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implantable jOint prostheses which have been under development for more than 25 years, are today being used with success in the rehabilitation of many cases, including patients with extremely severe joint pathology. However, artificial joint designs still pose problems with respect to their function, anchoring, materials employed and the interaction of the prosthesis with the surrounding biological tissues. Some of these problems are associated with considerable therapeutic complications. Further improvement in the artificial joint requires the application of all the modern experimental and research techniques and the close cooperation of medical doctors, engineers and scientists. The International Symposium on Advances in Artificial Hip and Knee Joint Technology held at Erlangen on October 30 and 31, 1975 under the auspices of the Societas Physica Medica Erlangensis, had as its aim the promotion of just this interdisciplinary cooperation. One of the traditional objectives of the Societas has been the advancement of diagnosis and therapy by the adaptation of medical skill to modern technology and scientific engineering concepts. The major objective of this volume is to present, in expanded form, the lectures given by internationally recognized scientists and clinical researchers in the field of artificial joints in the locomotor system, and to make that information available to a wider public. The experience discussed covers the principles and primary methods of joint replacement.

Download or read book Biomechanics of the Hip written by P.G.J. Maquet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: As recently as 20 years ago, ceramics were widely ignored as potential biomaterials. Interest in bioceramics has increased dramatically over the past decade to the point where it is anticipated they will be the materials of choice for many orthopedic, otologic, maxillofacial and dental applications during the decade of the '90s. Alumina ceramics are being used extensively as articulating comJ1onents in total joint prostheses because of Ithe materials low coefficient of friction and excellent wear resistances. Alumina ceramics are also being used in dental and maxillofacial applica tions because of the materials excellent biocompatibility. Because of its ability to chemically bond to bone, hydroxyapatite is rapidly becoming the material of choice for many dental and maxillofacial applications. For the past decade, one of the most widely researched topics in the field of orthopedics has been the clinical evaluation of joint prostheses based upon stabili zation via tissue ingrowth. It appears that the next generation of joint prostheses will be based upon direct chemically bonding to bone using hydroxyapatite, surface-active glass or surface-active glass ceramics coatings. Resorbable bioceramics are limited to temporary bone space fillers, periodontal pockets treatment and resorbable pharma ceutical delivery systems. Bioceramics is a comprehensive reference textbook covering the history of bio ceramics, present status of bioceramics, and prediction for future use of bioceramics. This book will serve as a major reference for students, as well as experienced bio material researchers. The book presents the state-of-the-art of bioceramics as of 1991.

Download or read book International Review of Connective Tissue Research written by David A. Hall and published by Academic Press. This book was released on 2013-10-22 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Review of Connective Tissue Research, Volume 8, provides an overview of the state of knowledge in connective tissue research. The details of the structure of collagen and its biosynthesis are now well established, and attention has focused on the finer details of the biochemical mechanisms involved. The knowledge achieved so far is also being applied to studies of various physiological, developmental, and pathological mechanisms involving the connective tissues. These trends are reflected in the subject covered by this volume. The enzymes involved in the posttranslation modifications of collagen are being intensively investigated. The book deals with three of these: lysyl oxidase, the enzyme involved in the first stage of cross-link formation; and the two glycosyl transferases involved in the glycosylation of hydroxylysome residues. New collagen types are reviewed together with recent work on collagen messenger RNA. Both of these topics are important to the understanding of the control of collagen biosynthesis. The involvement of connective tissues in physiological and pathological processes is discussed in three areas. These are interaction of collagen with platelets in hemostasis; the biosynthesis of connective tissue components by smooth muscle cells; and biochemical research on the intervertebral disc, the disease of which is behind the majority of back pain problems.

Download or read book Arthritis written by H. Deicher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rheumatoid arthritis is a common disease, an estimated 1. 5% of the population being under medical treatment for it in European countries and elsewhere. However, to date the origin of this chronic inflammatory disorder has not been elucidated. Evidence for the involvement of microbial agents is still tenuous, the rea son for the defective control of inflammation is still unknown, and the disease all too of ten progresses to crippling stages despite long-term treatment. As T. McKeown recently stated with regard to rheumatoid arthritis, "not enough is even known to indicate which is the more promising approach, and the pru dent course is to investigate both origins and mechanisms". While working on animal model diseases as well as on aspects of rheumatoid arthritis and related disorders in man, the members of the Special Research Area on patho physiology of rheumatoid inflammation in man and. animals (Sonderforschungsbereich 54 "Pa thomechanismen der rheumatoiden Entztindung bei Mensch und Tier"; maintained by the Deut sche Forschungsgemeinschaft) at the Veterinary and Medical Schools, Hannover, have been guided by the concept that by studying clinically and morphologically similar diseases in several species, mutually stimulating results might lead to improved knowledge of the pathophysio logy of rheumatoid arthritis. In particular, from working with model diseases in animals new approaches to the etiology of rheumatoid arthritis might be derived, while detailed knowledge of pathogenetic processes in rheu matoid arthritis could further research in chronic stages of pertinent animal diseases

Download or read book The Knee Ligament and Articular Cartilage Injuries written by D. E. Hastings and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editorial group has selected these papers for publication in Progress in Orthopaedic Surgery from contributions to the "Reisensburg Workshop of Clinical Trauma Surgery" dealing with the lesions of knee ligaments and cartilage in 1975. They represent a survey of today's knowledge of pathophy siology, diagnostic means, and therapy of these lesions in the German-speaking countries. There are two "Reisensburg Workshops" annually, covering current topics of traumatology sponsored by the Ulm trauma group. Primary attention is focused not upon review lectures but rather upon the extensive discussions thus resulting in recommendations to the practising trauma surgeon in order to facilitate his clinical work. Ulm, November 1977 C. Burri, A. Ruter Introduction This volume of Progress in Orthopaedic Surgery presents a selection of papers dealing with injuries to the ligament support and articular surfaces of the knee. The menisci are not discussed as separate entities, but rather in their correct perspective as part of the knee jointsupport mechanism. As the editor for this volume, I have tried to select the most representative articles which cover this subject. These are publications from our European colleagues and reflect their opinion and experience. I have tried not to change their content or meaning in any way. This volume has been divided into six basic segments. Each deserves comment.

Download or read book The Joints and Synovial Fluid written by Leon Sokoloff and published by Academic Press. This book was released on 2014-05-10 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joints and Synovial Fluid II is a collection of papers that deals with the basic aspects of the articular apparatus, including the general pathology of the appendicular and axial structures, the disease processes, and comparative anthology. Some papers discuss in vitro culture of joints and articular tissues, the chemistry of the ground substance of joint cartilage, and the structure of the intervertebral disc in relation to its function and to the aging process. As a humans being ages, the whole nucleus found in the disc will behave more like a sponge than a shock absorber as regards its ability to distribute stress and pressure from the end plates of the disc. Another paper describes load distribution of the knee, ankle joint, the spine, the arms, elbows, fingers. One paper deals with the pathology of the spine covering infectious diseases, metabolic and developmental disease of cartilage and bones, traumatic and degenerative diseases, autoimmune connective tissue diseases (such as ankylosing spondylitis), and miscellaneous diseases (such as tumors). The collection is suitable for researchers, scientists, medical practitioners, and academicians in the fields of biochemistry, bioengineering, anatomical sciences, immunology, organ physiology, cell biology, orthopedics, rheumatology, or rehabilitation medicine.

Download or read book Surgery and Arthroscopy of the Knee written by E.L. Trickey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a record of the papers read at the first meeting of the European Society of Knee Surgery and Arthroscopy (ESKA). This was held in the magnificent International Congress Centre (ICC) in West Berlin. Planning for the inaugural meeting of a proposed large society is inevitably fraught with problems and doubts. However, thanks to the tremendous assistance given by the ICC organization and to the participation of so many orthopaedic surgeons from Europe and all over the world the society had a very successful meeting, and it is fitting that the papers are collected together in this book as a permanent record. Various factors combined to delay the appearance of the book until now, shortly before the second ESKA meeting (1986) in Basle. We should like to take this opportunity of thanking Springer-Verlag for all the hard work involved in ensuring that the book was finished before this occasion and while the subject matter is still so topical.

Download or read book The Cementless Fixation of Hip Endoprostheses written by E. Morscher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main problem with regard to alloplastic joints is the loosening of the implant. Twenty years ago, Charnley first introduced bone cement to hip surgery, enabling total hip replacement to be practised on a larger scale. There is no question, however, that new approaches must be found to solving the problems of implant loosening, either by developing a new type of cement or by directly anchoring the implant without using ce ment. Much research has been done in this direction in recent years. The methods which have already been tested or are currently being tested were presented and discussed at a symposium on Cementless Fixation of Endoprostheses organized by the Orthopaedic Clinic of the University of Basel and held on 24-26 June 1982. Various possible ap proaches which might be realized in practice were discussed in a relaxed atmosphere. In addition to the biomechanical bases of cementless fixa tion of endoprostheses, the various models were discussed, with special regard to their biocompatibility, physical characteristics, design, clinical applicability, and previous clinical experience. This book contains the papers delivered at this symposium.

Download or read book Computational Modeling in Biomechanics written by Suvranu De and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Availability of advanced computational technology has fundamentally altered the investigative paradigm in the field of biomechanics. Armed with sophisticated computational tools, researchers are seeking answers to fundamental questions by exploring complex biomechanical phenomena at the molecular, cellular, tissue and organ levels. The computational armamentarium includes such diverse tools as the ab initio quantum mechanical and molecular dynamics methods at the atomistic scales and the finite element, boundary element, meshfree as well as immersed boundary and lattice-Boltzmann methods at the continuum scales. Multiscale methods that link various scales are also being developed. While most applications require forward analysis, e.g., finding deformations and stresses as a result of loading, others involve determination of constitutive parameters based on tissue imaging and inverse analysis. This book provides a glimpse of the diverse and important roles that modern computational technology is playing in various areas of biomechanics including biofluids and mass transfer, cardiovascular mechanics, musculoskeletal mechanics, soft tissue mechanics, and biomolecular mechanics.
