The biomechanics analysis of anatomical morphology of skeleton

The skeleton is a structural, load-bearing system, much of what we see in an adult´s bone morphology is a result of the history of skeletal loading during adolescence. The mechanics environments from daily activities play an important role in (re)modeling of an adult´s bone morphology. This paper, taking typical bones (e.g. proximal femur, proximal humerus and mandible) as examples, compared the principle stress vectors predicted by FE analysis under daily activities with orientations of trabecular bone from corresponding cadaver bone for finding out the relationships between mechanics environments and (re)modeling of bone morphology. The result shows essentially similar between principle stress vectors and orientations of trabecular bone, which can be as part of proofs of functional adaptation of bone. And together with bone remodeling simulations and some orthopedic clinical diseases were discussed for explaining bone functional adaption.
