10 Year Fracture Risk Calculator

Introduction: Welcome to the 10-Year Fracture Risk Calculator! This tool helps you estimate your probability of experiencing a fracture over the next decade based on key factors such as age, bone mineral density, previous fractures, and smoking habits.

Formula: The calculator uses a simplified formula to estimate the 10-year fracture risk: Fracture Risk=(0.2×Age)+(0.7×Bone Mineral Density)+(0.5×Previous Fracture)−(0.3×Smoker)Fracture Risk=(0.2×Age)+(0.7×Bone Mineral Density)+(0.5×Previous Fracture)−(0.3×Smoker)

How to Use:

  1. Enter your age in years.
  2. Input your bone mineral density in g/cm².
  3. Indicate whether you’ve had a previous fracture (0 for No, 1 for Yes).
  4. Specify your smoking status (0 for No, 1 for Yes).
  5. Click the “Calculate” button to determine your 10-year fracture risk.

Example: Suppose you are 50 years old with a bone mineral density of 0.9 g/cm², no previous fractures, and you don’t smoke. By clicking “Calculate,” you would find your estimated 10-year fracture risk, expressed as a percentage.


  1. Q: What does bone mineral density (BMD) measure? A: BMD measures the amount of mineral content in bone tissue, indicating bone strength. A lower BMD may increase fracture risk.
  2. Q: How is the 10-year fracture risk calculated? A: The calculator uses a formula considering age, BMD, previous fractures, and smoking status to estimate the likelihood of fractures over the next 10 years.
  3. Q: Why is age a factor in fracture risk? A: Fracture risk tends to increase with age as bone density decreases and bones become more susceptible to fractures.
  4. Q: How does previous fracture history affect the risk? A: Previous fractures are considered a risk factor, as individuals with a history of fractures may be more prone to future fractures.
  5. Q: Why is smoking status included in the calculation? A: Smoking can negatively impact bone health and increase fracture risk. The calculator considers smoking as a potential risk factor.
  6. Q: Can this calculator predict specific types of fractures? A: This calculator provides a general estimate of overall fracture risk. It may not predict specific types or locations of fractures.
  7. Q: Is this calculator suitable for everyone? A: The calculator is a general tool and may not account for all individual factors. Consult with a healthcare professional for personalized assessments.
  8. Q: Can lifestyle changes reduce fracture risk? A: Adopting a healthy lifestyle, including regular exercise and a balanced diet, may contribute to better bone health and reduce fracture risk.
  9. Q: Should I consult a healthcare professional for a more accurate assessment? A: Yes, for a comprehensive evaluation and personalized advice, consult with a healthcare professional, especially if you have specific health concerns.
  10. Q: Can the calculator account for other medical conditions affecting bone health? A: The calculator focuses on key factors. Individual medical conditions may require a more thorough assessment by a healthcare provider.

Conclusion: The 10-Year Fracture Risk Calculator offers valuable insights into your potential fracture risk based on essential factors. While this tool provides an estimate, it is crucial to consult with healthcare professionals for a more comprehensive assessment of your bone health and fracture risk. Making informed lifestyle choices and seeking medical advice can contribute to maintaining strong and healthy bones.
