Estimate fracture risk from common osteoporosis risk factors with a simplified educational screening checklist.
This osteoporosis risk calculator uses common fracture-risk factors to produce a simplified educational estimate of major osteoporotic fracture and hip fracture risk. It uses a FRAX-like input set that includes age, sex, BMI, prior fracture, parental hip fracture, glucocorticoid use, smoking, alcohol use, and rheumatoid arthritis.
Osteoporosis is a major cause of fractures, disability, and loss of independence, and hip fractures are especially serious in older adults. Estimating risk early can help identify people who may benefit from bone density testing, fall prevention, or treatment discussion.
This calculator is a simplified screening checklist rather than the official FRAX model, so its percentages should be read as directional checklist outputs rather than as formal treatment thresholds by themselves.
A short risk checklist can help decide when a fuller bone-health assessment is worth doing. It is especially useful for initial discussion, screening, or education before formal DXA and country-specific fracture-probability tools are used.
The score is most useful as part of a broader clinical conversation rather than as a stand-alone decision.
Simplified educational risk estimation: Base risk + age contribution + sex adjustment + risk factor contributions Risk factors scored: - Prior fragility fracture - Glucocorticoid use - Parental hip fracture - Female sex / post-menopause - Rheumatoid arthritis - Low BMI - Smoking - Alcohol use OSTA = 0.2 × (weight in kg - age in years)
Result: Checklist major-fracture context 11% — Moderate Checklist Risk
This simplified checklist output suggests enough risk to justify a fuller bone-health review. The next practical step is usually DXA plus formal fracture assessment rather than treating the number as a stand-alone prescription threshold.
This page is designed to summarize common fracture-risk factors quickly. It is useful for education and triage, but it is not a substitute for formal probability models or DXA results.
Country-specific FRAX models incorporate population-specific fracture and mortality data. That means the same risk factor pattern can translate into different formal probabilities depending on the model and whether bone density is included.
The most practical use of this page is deciding when someone should move from a broad screening conversation to a more formal osteoporosis workup.

This page uses a simplified, FRAX-like screening checklist built from familiar fracture-risk factors such as age, prior fracture, parental hip fracture, glucocorticoid use, smoking, alcohol, rheumatoid arthritis, and BMI. The score groups those factors into broad checklist bands and also reports the OSTA screening value.
It is intentionally not the official country-specific FRAX model and it does not use DXA data. The percentages on the page are directional checklist outputs meant for education and triage, not formal treatment thresholds.
No. This page is a simplified educational checklist that uses familiar fracture-risk factors, but it does not reproduce the official country-specific FRAX probability model. If a formal treatment decision depends on fracture probability, the official FRAX tool and DXA context are more appropriate.
A fragility fracture is a fracture from a low-energy event, such as a fall from standing height, that suggests bone fragility beyond what would usually be expected in healthy bone.
That depends on age, sex, prior fractures, medication exposures, and overall fracture risk. The calculator can help flag when a formal bone-density evaluation is worth discussing.
On DXA, osteoporosis is generally defined as a T-score of -2.5 or lower. Osteopenia falls between -1.0 and -2.5. Those thresholds come from DXA, not from this checklist.
Chronic glucocorticoid therapy can reduce bone formation, increase resorption, and raise fracture risk, which is why it is one of the major risk factors on fracture-assessment tools.
Weight-bearing exercise, adequate calcium and vitamin D, smoking cessation, limiting alcohol, fall prevention, and addressing frailty all remain important regardless of whether medication is eventually used.
