Brief description

This is a generalised systemic condition characterized by low bone mineral density and weakened bones that become prone to fractures. 

Confirming the diagnosis

Confirmation of the diagnosis may require:

  • Bone density test (DEXA scan) results, or
  • Radiological evidence of a minimal trauma fracture or loss of 20% or more of vertebral height due to fragility fractures

DEXA scans can pick up and confirm osteoporosis if an individual is identified as having risk factors and their medical history supports further testing (as determined by their treating doctor).

The T-score, used to assess the risk of osteoporosis and fractures, compares a person's bone density to that of a healthy young adult of the same sex at peak bone mass. A lower T score indicates a higher risk of osteoporosis and fractures (2.5 standard deviations below the mean compared to normal young adult sex-matched controls). 

Osteoporosis are often diagnosed by a general practitioner. Other medical specialists that may be involved in the diagnosis of this condition are endocrinologists.

Clinical onset

Clinical onset will be when bone densitometry results first confirmed the diagnosis based on the established threshold and criteria or when an osteoporotic fracture first occurred.

Clinical worsening

For worsening there would need to be evidence of an accelerated decrease in bone density, beyond that which occurs normally with age.
