What FRAX score justifies treatment?

Country-specific thresholds vary. In the US (NOF/BHOF): major osteoporotic fracture probability ≥20% OR hip fracture probability ≥3% justifies pharmacological therapy for patients with T-score between -1.0 and -2.5.

Does FRAX require BMD?

No. FRAX can calculate fracture probability using clinical risk factors alone. Adding femoral neck BMD T-score improves accuracy, especially in patients with low or high BMD extremes.

What risk factors does FRAX include?

Age, sex, weight, height, prior fracture, parental hip fracture, smoking, glucocorticoid use, rheumatoid arthritis, secondary osteoporosis, alcohol ≥3 units/day, and femoral neck BMD. Race/country selection adjusts absolute risk.

FRAX 10-Year Osteoporotic Fracture Probability

Calculate FRAX 10-year probability of major osteoporotic fracture and hip fracture. Integrates clinical risk factors with or without femoral neck BMD. Country-specific intervention thresholds guide bisphosphonate therapy.
