Spine surgery is evolving much like hip surgery did 30 years ago. It is progressing away from fusion towards mobility retention. The LINK SB Charité Artificial Disc is the only motion-retaining disc replacement for which there is long-term clinical experience with thousands of the devices having been implanted. In this book, the topic of artificial disc replacement is thoroughly discussed by the inventors and top spine specialists. Key features, such as the history of the SB Charité Disc, spinal anatomy, technical background, and clinical results are presented. This provides much valuable information to spinal surgeons interested in the state of the art of this exciting treatment. The SB Charité disc replacement, used in dedicated European centers for more than 10 years, is presently creating much interest in the Americas, too. This book is a must for anyone in the field of medicine interested in the operative treatment of low back pain.

Had we ever guessed the historical importance of this day, had we expected the impressive and touching episode of German history that took place on November 9, 1989, had we dared to hope that a dream three decades old would come true on precisely that day, we would have held our symposium in the immediate vicinity of the Branden burg Gate! While it is difficult to describe the atmosphere on that evening, when the news suddenly spread that "the wall had opened", it is almost impossible to describe the feeling of fraternity and sense of belonging that overcame everyone, a feeling that had been repressed (but never suppressed) for three decades!

Joint replacement is a very successful medical treatment. However, the survivorship of the implants could be adversely affected due to the loss of materials in the form of particles or ions as the bearing surfaces articulate against earch other. The consequent tissue and immune response to the wear products, remain one of the key factors of their failure. Tribology has been defined as the science and technology of interacting surfaces in relative motion and all related wear products (e.g., particles, ions, etc.). Over the last few decades, in an attempt to understand and improve joint replacement technology, the tribological performance of several material combinations have been studied experimentally and assessed clinically. In addition, research has focused on the biological effects and long term consequences of wear products. Improvements have been made in manufacturing processes, precision engineering capabilities, device designs and materials properties in order to minimize wear and friction and maximize component longevity in vivo. This book investigates the in vivo and in vitro performance of the orthopaedic implants and their advanced bearings. Contributions are solicited from the researchers working in the field of biotribology and bioengineering
