Do you know of someone who has fallen and broken a bone? Most of us do, but what you probably don’t know is that normal bones are very strong and should not break from a fall from standing height. When a bone breaks from falling, it is called a fragility fracture, most likely caused by osteoporosis. Osteoporosis can be avoided or minimized by knowing your risk and taking steps to manage your bone mass and strength. Dr. Timothy Manzone explains.
