Ultrasonic assessment of children’s cortical bone anisotropy
نویسندگان
چکیده
Child cortical bone tissue is rarely studied because of the difficulty of obtaining samples. Yet the preparation and ultrasonic characterization of the small samples available, while challenging, is one of the most promising ways of obtaining information on the mechanical behavior of non-pathological children’s bone. We investigated children’s cortical bone obtained from chirurgical waste. Stiffness cœfficients were evaluated via an ultrasonic method. We observe a transverse isotropy with the plane perpendicular to the bone axis as an isotropic plane for adults and children. Stiffness cœfficients were highly correlated with age in children.

Determination of Relationships between the Ultrasound Velocity and the Physical Properties of Bovine Cortical Bone Femur
Accurate measurements of physical characteristics of bone are essential for diagnosis, assessment of change following treatment, and therefore, indirectly, for evaluation of new forms of therapy. This is particularly true of osteoporosis and aging skeleton, in which fractures occur easily. Methods: In this study an ultrasonic system was set-up and calibrated on Plexiglas tubes of variable thick...
متن کاملThe relative influence of apatite crystal orientations and intracortical porosity on the elastic anisotropy of human cortical bone.
Elastic anisotropy exhibits spatial inhomogeneity in human cortical bone, but the structural origins of anatomic variation are not well understood. In this study, the elastic anisotropy of human cortical bone was predicted using a specimen-specific multiscale model that investigated the relative influence of apatite crystal orientations and intracortical porosity. The elastic anisotropy of cort...

متن کاملAnatomic variation in the elastic anisotropy of cortical bone tissue in the human femur.
Experimental investigations for anatomic variation in the magnitude and anisotropy of elastic constants in human femoral cortical bone tissue have typically focused on a limited number of convenient sites near the mid-diaphysis. However, the proximal and distal ends of the diaphysis are more clinically relevant to common orthopaedic procedures and interesting mechanobiology. Therefore, the obje...
متن کاملAnatomic variation in the elastic inhomogeneity and anisotropy of human femoral cortical bone tissue is consistent across multiple donors.
Numerical models commonly account for elastic inhomogeneity in cortical bone using power-law scaling relationships with various measures of tissue density, but limited experimental data exists for anatomic variation in elastic anisotropy. A recent study revealed anatomic variation in the magnitude and anisotropy of elastic constants along the entire femoral diaphysis of a single human femur (Es...
