Interactive FAQ
What is the difference between major and minor osteoporotic fractures?
Major osteoporotic fractures include hip, clinical spine, forearm, and shoulder fractures. Minor fractures typically involve the wrist, ribs, and other non-vertebral sites.
Can FRAX scores change over time?
Yes, FRAX scores can change over time due to changes in risk factors such as age, weight, and health status. It’s recommended to reassess your FRAX score every 2-5 years.
