Broken Bones Among Older People Increase Risk of Death for Up to 10 Years

Broken bones among older people increase their risk of death for up to 10 years, according to a new study, "Persistence of Excess Mortality Following Individual Non-Hip Fractures: A Relative Survival Analysis," published online ahead of print in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Older people with broken bones face a higher risk of death, and that risk can stay elevated for years. Hip fractures are known to increase the mortality risk among older people, and this is the first study to identify how long this risk lasts for different fractures. Nonhip fractures contribute to more than two-thirds of all fragility fractures and can include fractures of the femur, pelvis, clavicle, or lower leg.

"A fracture is the starting point for much wider health issues that persist long after the fracture has healed and can ultimately result in earlier death," says Jacqueline Center, MBBS, PhD, of the Garvan Institute of Medical Research in Sydney, Australia. "We tracked the increased risk of death for fractures in different bones and found that they vary. The heightened risk can last for over a decade after a hip fracture, and for most other fractures (apart from distal or minor fractures), the increased risk is for about five years."

This nationwide, registry-based follow-up study included all individuals in Denmark over the age of 50 who first experienced fragility fractures in 2001 and were followed up to 10 years for their mortality risk.

In the year after breaking a hip, men faced a 33% higher risk of death and women had a 20% higher risk. For femur or pelvic fractures, the one-year excess mortality was between 20% and 25%. A significant risk of death was still observed 10 years after a person broke a hip, and approximately five years following nonhip fractures.

"Our findings emphasize just how crucial early intervention is," Center says. "We need to understand the risk of breaking a bone before the fracture happens and treat that individual accordingly. While intervention after the first fracture is critical, we also need to diagnose those at risk of breaking bones before these major health impacts have occurred."
