How to Use This Calculator
- Enter the T-score from your DEXA scan report — this compares your bone mineral density to a young-adult reference (normal ≥ −1.0).
- Enter the Z-score from the DEXA report — this compares your BMD to age-matched peers (≤ −2.0 warrants secondary cause evaluation).
- Enter the patient's Age in years, Sex (0 = Male, 1 = Female), and BMI in kg/m².
- Indicate Prior fragility fracture (0/1) and Parent hip fracture history (0/1) — both significantly raise fracture risk.
- Review the WHO classification (Normal / Osteopenia / Osteoporosis), 10-year major fracture risk (%), 10-year hip fracture risk (%), and whether the treatment threshold is met.
