Bone Density and Mechanical Property

Abstract

Bone mechanical properties are largely determined by bone mass density, which is very similar to engineering materials such as foam, metal and composites. However, as a living material in the body, bone mechanical properties are also determined by many other physiological factors such as age, gender, race, and health conditions, and bone mechanical properties are highly subject-dependent. Acquisition of bone mechanical properties from a concerned subject in an in-vivo and non-invasive way is critical for biomechanical models to be applied in clinical assessment. Medical imaging technology has offered an effective way to acquire subject-specific bone mechanical properties.
