| Research Abstract |
Osteoporotic femoral neck fracture is associated with the change in bone mechanical properties that are determined by the tissue mineral density and micro-porous structure. To estimate bone fragility by osteoporosis non-invasively, we quantified the tissue mineral density and porous structure in the femoral cortex of patients with total hip arthroplasty, using a polychromatic micro CT system with K2HPO4 phantom. Our results showed that bone mineral density distribution could assume to be homogeneous, and indicated the importance of the porosity on the mechanical properties of cortical bone.
