Shear strength behavior of human trabecular bone.
The shear strength of human trabecular bone may influence overall bone strength under fall loading conditions and failure at bone-implant interfaces. Here, we sought to compare shear and compressive yield strengths of human trabecular bone and elucidate the underlying failure mechanisms. We analyzed 54 specimens (5-mm cubes), all aligned with the main trabecular orientation and spanning four an...
متن کاملQuantification of the roles of trabecular microarchitecture and trabecular type in determining the elastic modulus of human trabecular bone.
UNLABELLED The roles of microarchitecture and types of trabeculae in determining elastic modulus of trabecular bone have been studied in microCT images of 29 trabecular bone samples by comparing their Young's moduli calculated by finite element analysis (FEA) with different trabecular type-specific reconstructions. The results suggest that trabecular plates play an essential role in determining...
متن کاملThe modified super-ellipsoid yield criterion for human trabecular bone.
Despite the importance of multiaxial failure of trabecular bone in many biomechanical applications, to date no complete multiaxial failure criterion for human trabecular bone has been developed. By using experimentally validated nonlinear high-resolution, micromechanical finite-element models as a surrogate for multiaxial loading experiments, we determined the three-dimensional normal strain yi...
متن کاملLimited Trabecular Bone Density Heterogeneity in the Human Skeleton
There is evidence for variation in trabecular bone density and volume within an individual skeleton, albeit in a few anatomical sites, which is partly dependent on mechanical loading. However, little is known regarding the basic variation in trabecular bone density throughout the skeleton in healthy human adults. This is because research on bone density has been confined to a few skeletal eleme...
متن کاملCortical and Trabecular Bone
During the normal growth and development of man and animals the bones grow in length and width and undergo progressive changes in their architecture, a process known as maturation. These normal processes are governed by numerous and complex forces but one of them, the plane of nutrition during the growing period, is of major importance. Undernourished children are small in stature and have bone...
