FRAX (10-year fracture risk)

WHO 10-year probability of major osteoporotic / hip fracture.

What it is for

Osteoporosis risk assessment and treatment decisions (NICE NG259, July 2026, which replaced CG146; NOGG 2024).

FRAX uses a proprietary algorithm with 12 country-calibrated inputs (age, sex, BMI, prior fracture, parent hip Hx, smoker, glucocorticoid, RA, secondary osteoporosis, alcohol, optional BMD). Use the official UK tool.

Where to calculate it
