C H A P T E R 2 Joint Anatomy and Basic Biomechanics O U T L I N E FUNDAMENTAL CONCEPTS, PRINCIPLES, working in a wide variety of disciplines to communicate AND TERMS (see Appendix 3). Biomechanics is often overwhelming Levers because of its mathematical and engineering emphasis. Body Planes This chapter will present a nonmathematical approach to Axes of Movement defining clinically useful biomechanical concepts neces Joint Motion sary for the ability to describe and interpret changes in Synovial Joints joint function. Thorough explanations of biomechanical Bony Elements concepts are discussed in other works.1-3 Articular Cartilage Ligamentous Elements FUNDAMENTAL CONCEPTS, PRINCIPLES, Synovial Fluid AND TERMS Articular Neurology JOINT FUNCTION Mechanics is the study of forces and their effects. Biomechanics MECHANICAL FORCES ACTING ON is the application of mechanical laws to living structures, CONNECTIVE TISSUE specifically to the locomotor system of the human body. Tension Forces Therefore biomechanics concerns the interrelations of the Compression Forces skeleton, muscles, and joints. The bones for
