Richly illustrated throughout with actual tissue images, this innovative book shows that the soft-hard tissue junction is best understood in a biomechanical context. The authors describe their pioneering experimental methods, providing an essential structure-function framework for computational modelling, and thereby encouraging the development of more realistic, predictive models of this important tissue junction. Covering the three main musculoskeletal junctions of cartilage-bone, disc-vertebra, and ligament/tendon-bone, the relevant soft tissues are examined with respect to both their own inherent structure and their mode of integration with the hard tissue. The soft-hard tissue interface is explored with a focus on structural damage resulting from overloading, and its associated pathologies. Adopting a multiscale approach, ranging in structural resolution from the macro to fibril levels, this is a must-have guide to the field and an ideal resource for researchers seeking new and creative approaches for studying the joint and spine tissues.
