Why fragility fracture is a longevity inflection point
Tsteoporosis is asymptomatic until the first fragility fracture occurs — vertebra, wrist, hip. That first fracture changes the longevity trajectory: second fracture risk multiplies by 2-5, and each subsequent fracture accelerates functional deterioration. Hip fracture is the most devastating event — approximately 20% mortality at 1 year and sustained autonomy loss in many survivors.
Screening with DEXA (bone densitometry) and FRAX tool (10-year fracture risk) is well established. USPSTF 2018 recommends screening in women ≥65 and in women <65 with significant risk factors. In men with risk factors (prolonged corticosteroid, hypogonadism, ADT for prostate cancer) it's also indicated. Modern treatment (bisphosphonates, denosumab, romosozumab, teriparatide) significantly reduces fracture risk.
A fragility fracture changes the longevity trajectory. Screening osteoporosis before it occurs is oncology-equivalent secondary prevention.
