A 10-year FRAX probability above what percent indicates high risk for a hip fracture?

• A. 1%
• B. 5%
• C. 10%
• D. 3%

Answer: (D)

FRAX estimates the chance of a hip fracture over the next 10 years using age, sex, and various risk factors. When deciding who might benefit from treatment, guidelines use a threshold to label someone as high risk. For hip fracture, a 10-year probability of about three percent is commonly used as the cutoff for high risk. Crossing this threshold means the likelihood of a hip fracture is sufficient to consider starting preventive therapy, given the substantial impact a hip fracture can have on health and independence in older adults. Keep in mind that exact thresholds can vary by country and guideline updates, but three percent is the typical benchmark used in many contexts.
