1. What is the FRAX Score?

The FRAX® tool is a computer-based algorithm that calculates the 10-year probability of a major osteoporotic fracture (hip, clinical spine, humerus or wrist fracture) and the 10-year probability of hip fracture.

2. How Does the Calculator Work?

The calculator estimates fracture risk based on clinical risk factors with or without bone mineral density (BMD):

Key Factors:

• Age (40-90 years)
• Gender
• Weight and height (for BMI calculation)
• Previous fracture
• Parent hip fracture
• Current smoking
• Glucocorticoid use
• Rheumatoid arthritis
• Secondary osteoporosis
• Alcohol consumption (3 or more units/day)

3. Importance of Fracture Risk Assessment

Details: Identifying individuals at high risk of osteoporotic fractures helps guide decisions about prevention and treatment strategies.

4. Using the Calculator

Tips: Enter accurate age, weight, height, and check all relevant clinical risk factors. The tool is validated for ages 40-90.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a high FRAX score?
A: Generally, ≥20% for major osteoporotic fracture or ≥3% for hip fracture indicates high risk.

Q2: Can FRAX be used with BMD?
A: Yes, FRAX can be calculated with or without femoral neck BMD.

Q3: What populations is FRAX validated for?
A: FRAX has been validated in many countries but may need adjustment for specific ethnic groups.

Q4: How often should FRAX be recalculated?
A: Reassessment is recommended when clinical risk factors change significantly.

Q5: Can FRAX be used for treatment monitoring?
A: No, FRAX is for initial risk assessment, not for monitoring treatment response.
