    "description": "Most people over fifty have heard that hip fractures are serious, but the lifetime probability is systematically underestimated. Hip fracture is mentally filed alongside dramatic falls — a frail person slipping on ice — rather than as a near-universal late-life risk with a one-in-seven lifetime probability for women. That up to one in five patients dies within a year of the fracture is rarely part of the public narrative, which tends to treat hip fracture as painful but recoverable.\n",

The sex gap (women ~15%, men ~6%) is the most consistent finding in the literature, driven by lower peak bone density in women and greater survival into very old age. Hip fracture mortality is high — up to 20% of patients die within a year, though only about 30% of those deaths are causally related to the fracture — partly because the fracture itself disrupts mobility and triggers downstream complications — infection, thrombosis, deconditioning — rather than because the fracture directly kills. Fall-prevention interventions and osteoporosis screening (USPSTF, FRAX tool) can substantially modify personal risk; this is a risk amenable to clinical action.\n",
