Abstract: A bone analysis apparatus capable of calculating a more highly reliable fracture risk evaluation value. A bone density of the invention is positioned for a partial description of a fracture risk. That is, in the invention, it is considered that an accurate fracture risk cannot be sufficiently obtained only by one of the bone density and a structural parameter although both the bone density and the structural parameter are important to know the fracture risk. According to the invention, the fracture risk is comprehensively evaluated on the basis of the structural parameter for evaluating a structure of a trabecular bone in addition to the bone density. With this configuration, since the fracture risk can be evaluated while also taking the structure of the trabecular bone into consideration, the fracture risk can be more accurately evaluated.
