What is Osteoporosis?

Osteoporosis literally means “porous bones.” Osteoporosis is the most common bone disease in humans. Its characteristics include low bone mass, decreased bone strength, and an increased risk of fracture (broken bone). The clinical diagnosis of osteoporosis is when an individual falls from standing height and sustains a fracture.

The World Health Organization definition of osteoporosis is when bone mineral density (BMD) is less than or equal to -2.5 standard deviations or greater at the hip or spine using dual x-ray absorptiometry (DXA), based on a young normal population. This value is termed a T-score. Osteopenia is defined as “low bone mass,” in which the T-score is between -1.0 and -2.5.
