| Case | Age | Sex | BMI | T-score | Major Risk % | Hip Risk % | Band |
|---|---|---|---|---|---|---|---|
| Case A | 52 | Female | 26 | -0.8 | 1.3 | 0.3 | Lower relative risk |
| Case B | 66 | Female | 24.1 | -2.2 | 24.7 | 7.4 | Higher relative risk |
| Case C | 74 | Male | 23 | -2.6 | 53.5 | 28.3 | Higher relative risk |
| Case D | 83 | Female | 21.1 | -3.1 | 78 | 56.8 | Higher relative risk |
This page estimates long term fracture probability from structured clinical inputs. It uses age, sex, body size, common bone health risk flags, and an optional femoral neck T-score. The design is useful for screening workflows, education, and quick scenario comparison.
The page keeps the layout simple. Results appear below the header and above the form after submission. Users can compare outputs, review the driver list, inspect the graph, and export a compact summary for records or discussion.
This is an educational calculator. It does not replace clinical assessment, official fracture tools, imaging review, medication planning, or local guideline judgment. It is best used for structured review before a fuller evaluation.
1. BMI
BMI = weight in kg / (height in meters)^2
2. Major fracture score
Major score = baseline + age term + sex term + BMI term + weighted clinical factors + T-score term
3. Hip fracture score
Hip score = baseline + age term + sex term + BMI term + weighted clinical factors + T-score term
4. Probability conversion
Probability = 100 / (1 + e^(-score))
This implementation uses an educational weighted FRAX-style scoring method. It is meant for structured estimation only. It does not recreate the official country-specific probability engine.
No. This file uses a FRAX-style educational model. It mirrors the common public input structure, but it does not claim to reproduce the official country-specific probability calculation.
Yes. Leave the T-score blank. The tool will estimate risk from clinical factors and body size only. Adding the T-score can refine the estimate.
The form is designed around the usual public FRAX age window. Keeping that range helps keep the educational estimate closer to common screening use.
It means the weighted inputs point toward a greater relative probability of a future major osteoporotic fracture over ten years. It is a screening estimate, not a diagnosis.
Use it for a clinically important prior fracture history relevant to bone fragility review. When uncertain, confirm the history before relying on the estimate.
Yes. The same form works for both. The internal weighting adjusts by sex, age, body size, and other checked risk factors.
Exports help with record keeping, case discussion, and quick comparison. CSV is useful for data handling. PDF is useful for printing or sharing a compact report.
No. Medication, imaging, fall history, lab work, and local guidance still matter. Use this page as a structured starting point for review.
