About one in five adults over 65 dies within a year of breaking a hip. The overall one-year mortality rate is roughly 21%, though that number varies widely depending on age, sex, and health before the fracture. A hip fracture is one of the most serious injuries an older person can experience, not because the bone itself is fatal, but because of the cascade of complications that follow.
Survival by Age Group
Age at the time of fracture is the single strongest predictor of how long someone will live afterward. In a study of 758 patients aged 60 and older, the one-year mortality rates broke down like this:
- Ages 60 to 69: 2.1%
- Ages 70 to 79: 14.4%
- Ages 80 to 89: 22.8%
- Ages 90 and older: 27.5%
The jump between the 60s and 70s is dramatic. A 65-year-old who breaks a hip has excellent odds of surviving the year. An 85-year-old faces roughly a one-in-four chance of dying within 12 months. By five years out, about 55% of hip fracture patients are still alive, though many have lost significant independence.
The First 30 Days Are the Most Dangerous
Roughly 3% of patients die within 30 days of being hospitalized for a hip fracture. That rate has been improving over time, dropping from about 3.8% in 2000 to 2.9% by 2015 as surgical techniques and hospital protocols have advanced. Still, the first month carries the highest concentration of risk.
Heart disease and stroke are the leading causes of death in this window, accounting for 22% of deaths within 30 days. Falls and other accidental injuries cause another 18%, and cancer accounts for 10%. The fracture itself rarely kills anyone directly. Instead, the trauma of surgery, prolonged immobility, and stress on an already fragile body trigger fatal complications in the heart, lungs, or bloodstream.
Why Men Face Higher Risk
Men die at significantly higher rates than women after a hip fracture, at every time point. The 30-day mortality rate for men is 6.6% compared to 4.5% for women. At one year, 19.9% of men have died versus 15.1% of women. After adjusting for other factors, men have about 40% higher odds of dying within a year.
Part of the explanation is that men who break a hip tend to be sicker at baseline, with more chronic conditions. They’re also more prone to respiratory complications after surgery. Reduced lung clearance during recovery, combined with limited mobility, leads to pneumonia and other chest infections at higher rates.
Pre-Existing Conditions That Lower Survival
The health someone brings into the fracture matters enormously. A hip fracture in an otherwise healthy 80-year-old is a very different event than the same fracture in someone with heart failure and dementia.
Dementia is one of the strongest risk factors. Patients with dementia have twice the 30-day mortality of those without it: 12.8% versus 6.2%. After adjusting for age and other conditions, dementia raises the risk of dying within 30 days by 67%. The reasons are layered. People with dementia are more likely to develop post-surgical infections, less able to participate in rehabilitation, and face far higher rates of fatal complications from blood clots, pneumonia, and sepsis. Their risk of dying from sepsis specifically is double that of patients without dementia.
Heart failure, chronic lung disease, cerebrovascular disease, diabetes, and cancer all independently increase mortality risk. Among women with three or more serious chronic conditions, 15 additional deaths per 100 patients were observed in the year after fracture compared to the general population. The fracture itself accounted for about 6 of those deaths. The remaining 9 were caused by the interaction between the fracture and pre-existing disease, meaning the fracture accelerated conditions that might not have been fatal on their own.
What Kills People After a Hip Fracture
Hip fractures are dangerous because they force older adults into a state of immobility and physiological stress that their bodies often cannot recover from. Lying in bed for days or weeks raises the risk of blood clots in the legs and lungs (pulmonary embolism), pneumonia from shallow breathing, and urinary tract infections from catheter use. Heart failure can worsen when fluid balance shifts during and after surgery.
Over the longer term, the causes of death in hip fracture patients mirror those in the general elderly population: heart disease, respiratory disease, cancer, and dementia. The fracture doesn’t introduce new diseases. It accelerates existing ones by stripping away the physical reserves and mobility that were keeping them in check.
Recovery and Independence
Survival is only part of the picture. Among those who live, many never return to their previous level of function. One year after surgery, only about 40% of patients are still living independently at home. New nursing home admissions occur in 42% of hip fracture patients, with the median time from surgery to admission being about five months.
The probability of eventually needing a nursing home continues to climb over time: 16% at one year, 27% at two years, and 35% at three years. For families, this is often the most practical concern. Even when a loved one survives the fracture, the loss of mobility and confidence can permanently change their living situation.
Does Faster Surgery Help?
There is a widely held guideline that hip fracture surgery should happen within 24 to 48 hours of admission, and most evidence supports this as a general principle for reducing complications. However, the benefit isn’t as straightforward as it sounds. A Japanese cohort study found no difference in one-year mortality, length of hospital stay, or functional ability at discharge between patients who had surgery within 48 hours and those who waited longer. Japan’s baseline one-year mortality rate of 10% is notably lower than the Western average, which may reflect differences in patient health, surgical approach, or post-operative care.
What is clear is that unnecessary delays, particularly those stretching beyond several days, increase the time a patient spends immobile and raise the risk of the very complications that drive mortality. Getting to surgery promptly remains the standard of care, even if the precise hour-by-hour benefit is debated.
What Determines How Someone Does
If you’re trying to gauge the outlook for a specific person, the most important factors are their age, their mental sharpness before the fracture, how many chronic health conditions they have, and whether they were living independently beforehand. A cognitively intact 75-year-old who was walking without assistance has a fundamentally different prognosis than a 90-year-old with dementia and heart failure.
Early mobilization after surgery, meaning getting out of bed and starting physical therapy within a day or two, is one of the strongest modifiable factors in recovery. Patients who begin moving early have lower rates of pneumonia, blood clots, and pressure sores, and they’re more likely to regain enough function to return home. Nutrition also plays a role, since many older adults arrive at the hospital already malnourished, which slows wound healing and weakens the immune response.
