Cemented Total Hip Arthroplasty (THA) remains one of the most successful procedures in Orthopaedic surgery. It has become very clear that it is the surgical expertise, in particular the quality of the cementing technique, which will affect long-term outcome and success. It is the intention of this book to provide an up-to-date comprehensive assessment of the entire field of cemented THA. Special emphasis has been given to practice-relevant aspects: well-illustrated and detailed operative steps as a practical guideline, a basic science chapter and long-term outcome data are provided. Minimally invasive surgery, modern perioperative management and patient fast tracking are covered. A number of highly respected experts have contributed to this in-depth compilation of the "state of the art" in 2005. This book is written and intended for both, trainees and established arthroplasty surgeons who are dedicated to perform a well-cemented THA.
G. H. I. M. WALENKAMP, D. W. MURRAY Since the first use of bone cement, there has been much discussion about this important tool in arthroplasty. Many authors consider the cemented prosthesis as the gold standard when evaluating the outcome of primary prostheses. In a large number of total hip arthroplasties, as registered in the Scandi navian Hip Registers, important differences in revision risks have been docu mented between hospitals. These differences are partly due to the use of di verse cement techniques. In the analysis of data, the influence of these tech niques, as well as the different cement types, is clear. A recent disaster with a newly developed cement also illustrated that the...
Successful biofunctional surface engineering will determine the future of medical devices such as orthopedic implants, stents, catheters, vaccine scaffolds, wound dressings, and extracorporeal circulation devices. Moreover, the biosensor and diagnostic chip technology will evolve rapidly due to the growing medical need for personalized medicine. A
Selection of the latest research in Arthurian studies. The essays in this volume present the most recent fruits of Arthurian scholarship, on texts from Perlesvaus to Albrecht's Jüngerer Titurel and the Prose BrutChronicle, together with a detailed examination of the role of Micheau Gonnot's Arthuriad in the evolution of Arthurian romance. The volume also includes an investigation of Arthurian prophecy and the deposition of Richard II. It is completed with an encyclopaedic treatment of Arthurian literature, art and film produced between 1999 and 2004, acting as a continuing update to The New Arthurian Encyclopedia. Contributors: BEN RAMM, FANNI BOGDANOW, ANNETTE VOLFING, HELEN FULTON, JULIA MARVIN, RAYMOND H. THOMPSON, NORRIS J. LACY
Methyl methacrylate (MMA) is the basic component of bone cements. To use it, a dough is prepared from the liquid and powder by mixing right before application, which is normally done by the operating team. During its working phase the dough is then inserted into the tissue where polymerization is completed. Thus, the final implant polymethyl methacrylate (PMMA) is only created at the implantation site. Besides methyl methacrylate, bone cements sometimes contain other methacrylates, such as butyl methacrylate. To achieve X-ray opacity, radiopacifiers (zirconium dioxide or barium sulfate) are added to the powder. Both the liquid and powder components contain additives (initiator and activator)...
New technologies, developments in implant design and advances in surgical technique have improved outcomes after joint replacement and decreased rate of complications. It is not a surprise that the number of arthroplasties increases steadily every year and nowadays more than one million patients undergo the procedure annually worldwide. This book is a sequel of a successful series dedicated to one of the fastest growing fields in orthopedics - arthroplasty. Aiming at dissemination of scientific research this book provides a profound overview of the recent evolution of technology and surgical techniques. New developments of implant design and current treatment strategies have been critically discussed by the contributing authors. The process of improving care for patients and standards of treatment requires straightforward access to up-to-date research and knowledge. The format of the publication allows easy and quick reference to shared ideas and concepts. We hope, that the current book will add significant contribution to the success of this endeavor.
Die Wirtschaftlichkeit der industriellen Produktion hängt ganz wesentlich von der optimalen Auswahl der Fertigungsverfahren ab. Produktivitätssteigerungen und Kostensenkungen sind nur erreichbar, wenn Produktionsplaner, Fertigungstechniker und Konstrukteure ausreichende Kenntnisse über die neuesten technologischen Entwicklungen zur Verfügung haben. In der 11. Auflage des bewährten Klassikers der Fertigungstechnik wurde das Kapitel Gießen aktualisiert und der Abschnitt Gießen von Motoren im Pkw-Leichtbau völlig neu erstellt. Das Kapitel Schweißen wurde aktualisiert und durch die Verfahren Aluminothermisches Schweißen, Bolzen- und Reibschweißen ergänzt. Auch die Additiven Fertigung...
