How to Use the FRAX Score Calculator

The FRAX Score Calculator is a comprehensive tool used to assess the 10-year probability of bone fractures. Follow these steps carefully to use it effectively.

Step 1: Input Personal Information

Begin by inputting your fundamental personal details:

  • Age: Enter your age in years. Ensure that your age falls between 40 and 90, as inputs outside this range will not be accepted.
  • Sex: Select your sex from the available options: Female or Male.
  • Weight: Input your weight in kilograms. Acceptable values range from 25 to 200 kg.
  • Height: Enter your height in centimeters, ensuring it is within the range of 100 to 250 cm.

Step 2: Health and Lifestyle Factors

Next, provide information regarding specific health and lifestyle factors that may influence fracture risk:

  • Previous Fracture: Indicate whether you have had any previous fractures by selecting Yes or No.
  • Parent Hip Fracture: Select Yes or No to indicate if your parent has had a hip fracture.
  • Current Smoking: Indicate your smoking status by selecting Yes or No.
  • Glucocorticoids: Specify whether you take glucocorticoids by selecting Yes or No.
  • Rheumatoid Arthritis: Indicate if you have rheumatoid arthritis by selecting Yes or No.
  • Secondary Osteoporosis: Select Yes or No to indicate if you have secondary osteoporosis.
  • Alcohol Consumption: Specify if you consume 3 or more units of alcohol per day by selecting Yes or No.

Step 3: Optional Bone Density Measurement

If available, provide your Femoral Neck Bone Mineral Density (BMD) in g/cm². This is an optional field, and the acceptable range is between 0.1 and 2.0 g/cm².

Step 4: Calculate Your Results

Upon entering all required information, the calculator will compute and display the following results:

  • BMI: The calculator will determine your Body Mass Index (BMI) using the formula:

    weight (kg) / (height (m)²), rounding to one decimal point and providing the result in kg/m².

  • 10-year Major Osteoporotic Fracture Risk: This percentage estimate considers various factors, including age, previous fractures, lifestyle choices, and gender influence.
  • 10-year Hip Fracture Risk: Another percentage estimate that accounts for age, previous and parental hip fractures, lifestyle, and gender.

Use these results in collaboration with healthcare professionals to better understand your fracture risk and possible preventive measures.
