The World Health Organization (WHO) has established a diagnostic criteria for osteoporosis using BMD T-scores which describes an individual's BMD in terms of the number of SDs by which is differs from the mean peak value in young, healthy persons of the same sex—currently more than 2.5 SDs below the mean as the criterion for osteoporosis. [5]
[48] [34] An osteoporosis epidemiologist at the Mayo Clinic who participated in setting the criterion in 1992 said "It was just meant to indicate the emergence of a problem", and noted that "It didn't have any particular diagnostic or therapeutic significance. It was just meant to show a huge group who looked like they might be at risk."
The US National Osteoporosis Foundation recommends pharmacologic treatment for patients with hip or spine fracture thought to be related to osteoporosis, those with BMD 2.5 SD or more below the young normal mean (T-score -2.5 or below), and those with BMD between 1 and 2.5 SD below normal mean whose 10-year risk, using FRAX, for hip fracture is ...
Factor X deficiency (X as Roman numeral ten) is a bleeding disorder characterized by a lack in the production of factor X (FX), an enzyme protein that causes blood to clot in the coagulation cascade.
Steroid-induced osteoporosis is osteoporosis arising from the use of glucocorticoids (a class of steroid hormones) analogous to Cushing's syndrome but involving mainly the axial skeleton. The synthetic glucocorticoid prescription drug prednisone is a main candidate after prolonged intake.
Thus, the WHO classification of osteoporosis and osteopenia in adults cannot be applied to children, but Z-scores can be used to assist diagnosis. [9] Some clinics may routinely carry out DXA scans on pediatric patients with conditions such as nutritional rickets, lupus, and Turner syndrome. [10]
It is an effective anabolic (promoting bone formation) agent [15] used in the treatment of some forms of osteoporosis. [13] [16] Teriparatide is a recombinant human parathyroid hormone analog (PTH 1-34). [13] It has an identical sequence to the 34 N-terminal amino acids of the 84-amino acid human parathyroid hormone.

Long-term treatment with bisphosphonates produces anti-fracture and bone mineral density effects that persist for 3–5 years after an initial 3–5 years of treatment. [2] The bisphosphonate alendronate reduces the risk of hip, vertebral, and wrist fractures by 35-39%; zoledronate reduces the risk of hip fractures by 38% and of vertebral ...
