FRAX 10-Year Fracture Probability

Estimate 10-year probability of major osteoporotic fracture and hip fracture using FRAX tool incorporating age, sex, BMI, clinical risk factors, and optionally femoral neck BMD T-score.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate 10-year probability of major osteoporotic fracture and hip fracture using FRAX tool incorporating age, sex, BMI, clinical risk factors, and optionally femoral neck BMD T-score

Each component has a specific meaning:

  • FRAX tool incorporating age — The frax tool incorporating age recorded for the scenario being assessed.
  • Sex — The sex recorded for the scenario being assessed.
  • BMI — The bmi recorded for the scenario being assessed.
  • Clinical risk factors — The clinical risk factors recorded for the scenario being assessed.
  • Optionally femoral neck BMD T-score — The optionally femoral neck bmd t-score recorded for the scenario being assessed.

Note: Interpret the frax fracture risk result against the thresholds and context described above.

How to Use

Enter the FRAX tool incorporating age, sex, BMI, clinical risk factors, optionally femoral neck BMD T-score for the scenario you are assessing. Estimate 10-year probability of major osteoporotic fracture and hip fracture using FRAX tool incorporating age, sex, BMI, clinical risk factors, and optionally femoral neck BMD T-score. Use the frax fracture risk result to inform your calculation.
