Document Summary
Alteration: is any change to the physical properties of a bone. Trauma: refers to the physical disruption of living tissues by outside forces. Trauma mechanism is usually categorized as blunt force, high velocity projectile, sharp force, thermal or some combination of these categories. Skeletal trauma often results from the application of force or the action of one object on another. The science that deals with the effects of forces on objects is called mechanics and bones are physical objects that obey mechanical laws. Loading: the application of force to an object. For normal loading, a material"s intrinsic stiffness is known as the elastic modulus or. Strain in bone has been reported to rarely exceed 3% Load and deformation are linearly proportional until the proportional limit or yield point is reached at which point the slope is reduced. When acted upon by a force less than the yield point, bone will react through elastic deformation.
