Most adults with a broken femur spend roughly five to fourteen days in the hospital for the acute stay, though the actual number depends heavily on where the bone broke, your age and overall health, how quickly surgery happens, and whether complications arise afterward. That range can shrink to a day or two for a young child with a simple fracture treated in a cast, or stretch well beyond three weeks for an older adult who develops an infection or delirium after surgery. The femur is the largest bone in the body, and fixing it is a significant operation, so even uncomplicated recoveries involve more hospital time than most people expect.
Where the Bone Breaks Matters
The femur runs from the hip to the knee, and fractures at different points along its length are treated quite differently. A break near the hip (the most common type in older adults) is what clinicians call a hip fracture, even though the bone that actually snaps is the femur. Fractures through the middle of the shaft, common in younger people after car accidents or high-energy falls, typically require an intramedullary nail driven down the center of the bone. Breaks near the knee (distal femur fractures) often need plates and screws. Each location brings its own surgical demands, weight-bearing restrictions, and complication profiles, all of which influence how many nights you spend in a hospital bed.
For hip fractures specifically, large studies report wide averages. A Japanese registry study found a mean stay of about 31 days, reflecting that country’s practice of keeping patients hospitalized through much of their rehabilitation.1PubMed. Length of hospital stay after hip fracture surgery and 1-year mortality A study from Peru found an average of 17 days for older adults.2PubMed Central. Determinants of Length of Hospital Stay in Older Adult Hip Fracture Patients in a Northern Peruvian Hospital In the UK and parts of Europe, modern orthogeriatric pathways have brought the average acute stay down to around 10 to 12 days.3PubMed Central. An orthogeriatric service can reduce prolonged hospital length of stay in hospital for older adults admitted with hip fractures Scottish audit data shows acute stays of 11 to 12 days depending on the implant used, with overall stays (including any time waiting for rehabilitation placement) averaging 20 to 24 days.4PubMed. Sliding hip screw constructs are associated with early mobilisation, return to domicile and shorter length of stay when compared to an intramedullary nail These differences between countries reflect healthcare system design as much as the injury itself.
How Quickly You Get to Surgery
One of the strongest predictors of how long you stay is how soon after admission the fracture gets fixed. When surgery is delayed beyond 48 hours, hospital stays climb substantially. A study of proximal femur fractures found that patients operated on after 48 hours stayed an average of about 33 days, compared with roughly 22 days for those who had surgery sooner.5PubMed. Delay to surgery prolongs hospital stay in patients with fractures of the proximal femur For femoral shaft fractures in patients with multiple injuries, waiting 48 to 120 hours for fixation added nearly three extra days of hospital stay compared with operating within the first 12 hours.6PubMed Central. Timing of Femoral Shaft Fracture Fixation Affects Length of Hospital Stay in Patients with Multiple Injuries
Surgery sometimes gets delayed for medical reasons: blood thinners need to be managed, cardiac issues need stabilizing, or the patient arrives at night when operating room resources are limited. But research consistently shows that when the delay is organizational rather than medical, every extra day of waiting adds to the total stay and may worsen outcomes. A separate analysis of operative femur fractures identified earlier fixation and aggressive management of medical complications as the two key modifiable factors for reducing time in hospital.7Journal of Orthopaedic Trauma. Determinants of Length of Stay After Operative Treatment for Femur Fractures This is why many hospitals now have protocols targeting surgery within 24 to 36 hours of admission for hip fractures.
Complications That Extend Your Stay
When recovery goes smoothly, the hospital stay is largely dictated by surgical healing and pain management. When something goes wrong, the clock resets. A large prospective study broke down exactly how much individual complications add:
- Wound infection: the biggest impact, more than tripling the average stay from about 7 days to 23 days.
- Delirium: increased the stay from about 7 days to 11 days, and is especially common in older patients.
- Acute kidney injury: pushed the stay from 7 to 11 days.
- Urinary tract infection: similarly extended stays from 7 to 11 days.
All of these effects were statistically significant.8Injury. Complication overview following hip fracture surgery: insights from a prospective multicenter cohort study Deep wound infections carry consequences beyond extra hospital days. A study comparing infected proximal femur fracture cases with matched controls found that infected patients were four and a half times less likely to survive to discharge and, if they did survive, three times less likely to return home. Infections with drug-resistant bacteria (MRSA) added even more time and cost than other infections.9PubMed. Deep wound infection after proximal femoral fracture: consequences and costs
These aren’t rare events in vulnerable populations. Delirium alone affects a sizable fraction of older hip fracture patients, and it does more than extend the hospital stay: it can derail the rehabilitation plan entirely, leaving patients weaker and more dependent at discharge.
Age and Frailty
Your physical condition walking into the hospital is one of the best predictors of how quickly you walk out. A study that sorted hip fracture patients by frailty level found that frail patients had a median stay of 14 days, pre-frail patients stayed about 10 days, and robust patients stayed around 8 days. Frail patients also had roughly twice as many total complications as their robust counterparts.10PubMed. Frailty, length of stay and cost in hip fracture patients Similarly, rehabilitation outcome data show that age and functional ability at admission strongly predict both length of stay and discharge destination. About half of patients in one rehabilitation cohort went home within 21 days, including virtually all patients under 69 or those who arrived with higher functional independence scores.11Geriatrics. Factors Influencing Length of Stay and Discharge Destination of Patients with Hip Fracture Rehabilitating in a Private Care Setting
What this means in practical terms: a fit 55-year-old who breaks their femoral shaft in a skiing accident has a fundamentally different hospital trajectory than an 85-year-old with heart failure who falls at home. Both have broken femurs. One might be home in a week; the other might be in hospital for three weeks before transferring to a rehabilitation facility for several more.
Broken Femurs in Children
Children break their femurs far less often than older adults, and when they do, hospital stays are dramatically shorter. For younger children (roughly under age five or six), the standard treatment is a spica cast, a rigid body cast that immobilizes the hip and leg. This can sometimes be applied in the emergency department without general anesthesia. One study found that spica casting done in the ED resulted in an average hospital stay of about 17 hours, while casting under anesthesia in the operating room took about 31 hours, still well under two days.12Journal of Pediatric Orthopaedics. Immediate Spica Casting of Pediatric Femoral Fractures in the Operating Room Versus the Emergency Department
For older children whose fractures need surgical fixation, stays are longer but still modest compared with adults. A study of pediatric femur fractures found median stays of 3 days for isolated fractures treated with a spica cast and 6 days for those needing operative fixation. When children had other injuries alongside their femur fracture, the stays stretched to 5 and 17 days respectively.13PubMed. Paediatric femoral fractures: factors influencing length of stay and readmission rate Children’s bones heal faster than adult bones, and the concern about prolonged immobility that dominates adult care is less pressing, so the push to get pediatric patients home comes sooner.
Getting Up After Surgery
How quickly you start moving after your operation has a real effect on when you go home. A study comparing early mobilization (getting out of bed the day after surgery) with later mobilization found that early movers had significantly shorter hospital stays: about five and a half days compared with nearly seven days.14Turkish Journal of Medical Sciences. Effects of early mobilization and weight bearing on postoperative walking ability and pain in geriatric patients operated due to hip fracture A larger analysis identified mobilization on the first day after surgery as one of the two strongest modifiable predictors of a shorter acute stay, alongside getting surgery done within 48 hours.15PubMed. Shorter acute hospital length of stay in hip fracture patients after surgery predicted by early surgery and mobilization
Early mobilization is safe. Research shows it does not increase complication rates compared with waiting longer to get patients upright.16PubMed Central. Early Mobilization Post–Hip Fracture Surgery Yet it remains underused. Pain, fear, understaffing on weekends, and patient reluctance all conspire to keep people in bed longer than necessary. If you or a family member is recovering from femur surgery, asking about the mobilization plan and pushing (gently) to follow it is one of the few things within your control that can genuinely shorten the hospital stay.
Which Implant Gets Used
For intertrochanteric hip fractures (the most common type in older adults), surgeons choose between two main devices: a sliding hip screw, which attaches to the outside of the bone, or an intramedullary nail, which goes inside the bone’s canal. The choice affects recovery time. A large database study of over 4,400 procedures found that intramedullary nails were associated with a shorter postoperative stay: about five and a half days versus six and a half days for the sliding hip screw.17Journal of Bone and Joint Surgery. Extramedullary Compared with Intramedullary Implants for Intertrochanteric Hip Fractures
Interestingly, data from Scotland’s national hip fracture audit tells the opposite story. Sliding hip screws were associated with shorter acute stays (11 versus 12 days) and shorter overall stays (20 versus 24 days) compared with intramedullary nails. Patients who received sliding hip screws also mobilized earlier and were more likely to be discharged home within 30 days.4PubMed. Sliding hip screw constructs are associated with early mobilisation, return to domicile and shorter length of stay when compared to an intramedullary nail An older comparison similarly found that intramedullary nails were associated with longer initial hospital stays and more rehabilitation days in the six months after discharge.18PubMed Central. Is a sliding hip screw or im nail the preferred implant for intertrochanteric fracture fixation?
The disagreement likely reflects differences in patient selection, fracture patterns, and local practice rather than one implant being universally better. The practical takeaway is that implant choice can swing the stay by a day or two, but it is rarely the dominant factor.
When Surgery Is Not an Option
A small number of patients, usually those who are extremely frail or have medical conditions that make anesthesia too risky, are treated without surgery. This used to mean weeks of bed rest in traction, which carried its own serious dangers (blood clots, pneumonia, pressure sores). More modern non-surgical protocols skip the traction and instead get patients into wheelchairs and moving as soon as possible. One study of 87 elderly patients managed this way found a mean hospital stay of 17 days and one-year mortality of 18%, comparable to surgical outcomes in similar populations.19PubMed. Outcomes of an accelerated nonsurgical management protocol for hip fractures in the elderly Non-surgical management remains the exception, not the rule, and is generally reserved for patients who would not survive an operation or who have a very limited life expectancy.
Social Circumstances and Discharge Delays
Here is something most people do not think about when they hear “hospital stay”: a meaningful chunk of days spent in hospital after a femur fracture has nothing to do with medical recovery. It is waiting. Waiting for a rehabilitation bed. Waiting for home modifications. Waiting for social services to arrange support. Patients who live alone or lack social support are significantly more likely to experience delayed discharge. One study found that social isolation tripled the odds of a delayed discharge and added about two and a half extra days to the hospital stay on average. Being referred to a publicly funded rehabilitation unit added nearly five extra days of waiting.20PubMed. The impact of social isolation on delayed hospital discharges of older hip fracture patients and associated costs
A scoping review of social factors in hip fracture recovery confirmed that social isolation is a consistent predictor of delayed discharge.21PubMed Central. Understanding the role of social factors in recovery after hip fractures Socioeconomic deprivation compounds the problem further. A study of distal femur fractures found that patients from more deprived areas were about twice as likely to have a prolonged stay, even after controlling for injury severity and baseline function.22PubMed. Social deprivation results in longer perioperative admission and decreased rates of home discharge after distal femur fracture
If you are helping plan a family member’s care, this is worth paying attention to early. Starting discharge planning on or before the day of surgery, identifying who will be at home, what equipment is needed, and whether a rehabilitation placement will be required can prevent days of medically unnecessary hospitalization.
Coordinated Geriatric Care Shortens Stays
One of the biggest changes in hip fracture management over the past decade has been the rise of orthogeriatric care models, where an orthopedic surgeon and a geriatrician share responsibility for the patient from admission onward. This is not just a feel-good team approach; it produces measurable differences. One hospital that introduced an orthogeriatric service saw its average stay for hip fracture patients drop from about 17 and a half days to around 10 days. The improvement held across all discharge destinations, including patients going home, to rehabilitation, and to residential care.3PubMed Central. An orthogeriatric service can reduce prolonged hospital length of stay in hospital for older adults admitted with hip fractures Having a geriatrician involved from the start means medical complications get caught and managed faster, medications are optimized for an older body, and delirium, one of the major stay-extenders, gets prevented or treated earlier.
Even in the emergency department, a multidisciplinary approach makes a difference. One study found that coordinated ED-based care for hip fractures cut the emergency department stay roughly in half: about three hours versus nearly five and a half hours, with better pain control as well.23PubMed Central. Orthogeriatric multidisciplinary care for hip fractures in emergency department reduces length of stay These gains compound. Faster ED processing leads to earlier surgery, which leads to earlier mobilization, which leads to fewer complications, which leads to earlier discharge. The system matters as much as the surgery.
High-Energy Trauma and Multiple Injuries
Everything discussed so far assumes the femur fracture is the main event. When a broken femur comes as part of a car crash, a fall from height, or another high-energy trauma with multiple injuries, the hospital stay enters a different category entirely. These patients often go to the ICU before surgery is even possible. A published case of a patient with bilateral femur fractures after polytrauma described two days of intubation in the ICU followed by transfer to the orthopedic ward on the ninth day after surgery, and that was just the beginning of the inpatient course.24PubMed Central. A case of damage control after polytrauma and bilateral femur fracture In polytrauma, the femur fracture is often managed using “damage control” principles: a temporary external fixator is placed first to stabilize the patient, and definitive fixation with a nail or plate comes days later once the person is stable enough for a longer operation.
Pediatric data illustrates the same pattern. Children with isolated femur fractures and operative fixation had a median stay of 6 days, but those with associated injuries stayed a median of 17 days.13PubMed. Paediatric femoral fractures: factors influencing length of stay and readmission rate The additional injuries, whether to the chest, abdomen, head, or other limbs, drive the extended stay far more than the femur break itself.
The Readmission Question
A shorter initial stay sounds appealing, but it is worth asking whether getting out faster just shifts problems to later. Research on 30-day readmission after hip fracture offers a nuanced picture. Patients who were readmitted had averaged about one extra day of hospitalization during their initial stay compared with those who were not readmitted (roughly 8 days versus 7 days). Patients whose first stay lasted eight days or longer were nearly twice as likely to need readmission.25PubMed Central. Readmission Within 30 Days of Discharge After Hip Fracture Care That might seem contradictory: longer stays predict readmission? But it makes sense when you consider that the patients who stay longest are the sickest, and their underlying complexity follows them home.
Finnish data reinforces that the shortest stays are not always the safest either. Patients discharged within four days of hip fracture surgery had the highest risk of dying within 30 days, nearly three times higher than those who stayed about three weeks.26PubMed Central. Length of Hospital Stay for Hip Fracture and 30-Day Mortality in People With Alzheimer’s Disease This does not mean longer stays are better by default. It means there is a sweet spot: long enough to manage acute recovery, treat complications early, and set up safe discharge, but not so long that hospital-acquired problems (infections, deconditioning, delirium) pile up. Determining that sweet spot for any individual patient is one of the hardest judgment calls in orthopedic and geriatric care.
What to Expect After Discharge
Leaving the hospital does not mean recovery is over. Depending on your age and functional level, you might go directly home, transfer to an inpatient rehabilitation facility, or move to a skilled nursing facility. A rehabilitation cohort study found that about 82% of patients eventually returned home, but the median rehab stay was about 21 days on top of whatever time they spent in the acute hospital.11Geriatrics. Factors Influencing Length of Stay and Discharge Destination of Patients with Hip Fracture Rehabilitating in a Private Care Setting For younger patients with femoral shaft fractures who go directly home, outpatient physical therapy typically continues for weeks to months. Weight-bearing restrictions may persist for six to twelve weeks depending on how the fracture was fixed and how healing progresses on follow-up X-rays.
The total time away from normal life, then, is considerably longer than the hospital stay alone. A week in the hospital might be followed by three weeks of inpatient rehab and then months of outpatient recovery. Planning for the full arc, not just the acute admission, saves families from scrambling at each transition point.
