Relationships between structure, density and strength of human trabecular bone.
The article deals with the examination of the relationships between density, structure parameters and strength of human trabecular bone. The tests were carried out on the samples taken from osteoporotic and coxarthrotic human femoral heads. The samples cylindrical in shape had the diameters of 10 mm and the height of 8.5 mm. During the tests with microCT scanner the parameters of a sample struc...
متن کاملShear 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 کاملIn Vivo Analysis of Trabecular Bone Architecture
Trabecular morphology has structural trends which are strongly correlated with physical function. In vivo analysis of the trabecular pattern has the potential to predict and treat malgrowth of bone owing to altered loading conditions in an early phase. Using multiscale texture analysis we determine the orientation trend of the trabecular network from CT images. First studies show that the obtai...
متن کاملRelationship Between Vertebral Bone Mineral Density and Strength
The relationship between bone mineral density and bone strength has been investigated as a ubiquitous property of bone. This study utilized 22 isolated vertebral body preparations which had their volumetric bone mineral density quantified and their compressive mechanics measured. Cadaveric baboon ninth thoracic vertebral body samples were investigated which ranged in age from 1 to 30 years and ...
متن کاملTrabecular shear stress amplification and variability in human vertebral cancellous bone: relationship with age, gender, spine level and trabecular architecture.
Trabecular shear stress magnitude and variability have been implicated in damage formation and reduced bone strength associated with bone loss for human vertebral bone. This study addresses the issue of whether these parameters change with age, gender or anatomical location, and if so whether this is independent of bone mass. Additionally, 3D-stereology-based architectural parameters were exami...
