Objective: Femur is the strongest, longest and heaviest bone in the human body. Due to the great importance of femur in human body, its injury may cause large numbers of disabilities and mortality. Considering various effective parameters such as mechanical properties, geometry, loading configuration, etc. can propel the study to the trustable results.. Methods: A 3D finite element model of the...

conclusions in contrast to the findings in humans and certain other species, glucocorticoid administration caused anabolic effect on the cortical bone of tibia diaphysis bone in rats. results glucocorticoid-treated rats showed weight loss and considerable mortality (21%). the biomechanical properties (maximum force) of glucocorticoid-treated rats in groups 4 (62 ± 2.9), 6 (63 ± 5.1), and 7 (60 ...

ꞵ-tricalcium phosphate (ꞵ-TCP) and anorthite are the main crystalline components in bone china bodies. The difference in their thermal expansion coefficients causes a decrease in the thermal shock resistance of the body. In this study, anorthite was replaced with bone ash at the bone china body, and the effect of this new composition on different properties of bone china, after curing at 1260 °...

OBJECTIVE To investigate the influence of decreased mechanical loading on the density and mechanical properties of the cancellous bone of the human mandibular condyle. DESIGN Destructive compressive mechanical tests were performed on cancellous bone specimens.Background. Reduced masticatory function in edentate people leads to a reduction of forces acting on the mandible. As bone reacts to it...

Introduction Current methods for the assessment of fracture risk in osteoporosis are primarily based on bone mineral density (BMD) measurements. The mechanical properties of bones, however, are not only related to its density, but also to its internal architecture and its tissue properties. A non-invasive measurement of bone mechanical properties that accounts for the in-vivo bone internal arch...

Research in cancellous bone has grown exponentially over the last 20 years and is still going on. The knowledge of the mechanical properties of cancellous bone will enhance the understanding of bonerelated fracture. Cancellous bone is a highly porous or cellular form of bone. Unlike most metal properties, cancellous bone is non-isotropic and its mechanical properties (elastic modulus, yield str...
