This new reference explains the role of biomechanics, the study of the mechanics of the living body, and the forces acted upon it, in accident and injury cases. This book gives you an in-depth look at the area of human injury biomechanics. It also discusses the role of the biomechanist and when and how he or she can help with your investigation. The authors discuss biomechanical causation versus medical causation, the basic principles of biomechanics, approaches to the use of biomechanics in investigation, and application of biomechanical principles to impact injuries. They also provide detailed information on the biomechanics of the human body including bone tissue, articular cartilage, soft tissue, blood and fluids, spinal cord and nerve tissue, joints, and extremities.

This book contains over 300 diagrams and images plus a DVD of cadaver photos illustrating the principles discussed. This book is invaluable if you are working on an accident or injury case, and need to understand the principles of the biomechanics behind the injury.
