OSTEOPOROSIS

Question 1

What T-score indicates a diagnosis of osteoporosis?

Answer 1

T-score ≤ -2.5 standard deviations (SDs) on dual-energy x-ray absorptiometry (DXA)

T-scores are used to assess bone mineral density (BMD) and risk of fractures.

Question 2

What T-score range indicates increased risk of major osteoporotic fracture?

Answer 2

T-score -1 to -2.5 SD in patients at increased risk of major osteoporotic fracture

Patients in this range may require further evaluation and monitoring.

Question 3

What history confirms a diagnosis of osteoporosis regardless of BMD?

Answer 3

History of a major osteoporotic fragility fracture

Fragility fractures occur from a fall from standing height or less.
