title: [Absolute risk for fracture and WHO guideline. Recent interest in bone quality].
abstract: Among several recent interests in bone quality, two topics will be stated. First, in vivo assessment of bone microstructure has been realized by the benefit of recent developments of imaging technique and technology, which is going to be applied to assess risk of fracture and efficacy of anti-osteoporotic agents. Second, in vitro analyses of nano-structure, including microcrack and cortical porosisty, contribute to assessment of bone material and biomechanical properties.
