By definition Biomechanics is the application of engineering methods to study the mechanical aspects of living beings. Mostly the life scientists have the questions but lack of the specialized methods. The engineers on the other hand can handle very specialized equipment and methods, but lack in the biological thinking. If both sides are able to adapt to each other, Biomechanics is a classical field of interdis­ ciplinary cooperation. In the beginning, most biomechanical research was done in the field of orthopaedics. But other areas like cardiovascular research, dentistry, sports and many others gain increasing importance. This situation is clearly reflected in this book, which contains a selected number of papers which were presented at the Fifth Meeting of the European Society of Biomechanics, held in September 1986 in Berlin. Meanwhile these meetings have become a well accepted forum and a place of interdis­ ciplinary discussion for scientists in Biomechanics on the one side and surgeons and other peoples interested in biome­ chanical solutions on the other. It is the third time that the proceedings are published as a book and the editors are sure that this volume will help to establish this series "Developement in Biomechanics" as a valuable tool for all people involved in Biomechanics. The Fifth Meeting of the ESB also marks the tenth anniversary in the short history of the European Society of Biomechanics.
