The official FRAX® algorithm is a proprietary model that calculates absolute fracture risk based on country-specific epidemiologic data.
Treatment is usually recommended if 10-year probability of hip fracture is ≥ 3% OR probability of major osteoporotic fracture is ≥ 20% (US National Osteoporosis Foundation).
