Postmenopausal osteoporosis

Postmenopausal Osteoporosis is a pathological condition of human skeleton that is characterized by the following features :

• low bone mass
• bone fragility caused by worsening of microarchiectural properties of the bone
• consequent suseptibility to fractures

Osteoporosis is assesed, according to WHO criteria, as BMD (bone mineral density). So called T-score is a representation of patient's BMD expressed as number of standard deviations below or above mean BMD of the young adult.

T-score values below 2.5 SD are defined as characteristic of osteoporosis. Values between -1 SD and -2.5 SD are defined as osteopenia?.
