- G020031 HAp Crystal Properties and Elastic Modulus of Single Trabecula in Bovine Cancellous Bone
抄録
The aim of the study was to elucidate the difference of elastic modulus and hydroxyapatite (HAp) crystal properties between single trabecula and cortical bone. The study used trabecular specimens obtained from the cancellous bone in proximal bovine femurs. In the experiments, the angle between the longitudinal axis of the trabecular specimen and the longitudinal axis of the femur was measured by CT imaging. To measure the elastic modulus of the trabecular specimens, tensile test was conducted using a material testing machine. The c-axis orientation of HAp crystals and the degree of orientation were measured by X-ray diffraction technique. Further, the HAp crystal strain was also measured under tensile loadings. As a result, elastic modulus had a statistical negative correlation with the angle between the longitudinal axis of the trabecular specimen and the longitudinal axis of the femur. The c-axis of HAp crystals was aligned along the longitudinal axis of the trabecula and the degree of orientation was lower than that in bovine cortical bone Further, the HAp crystal strain was lower than that in bovine cortical bone.
