# Hip Fracture

Hip fracture requires rapid confirmation, perioperative medical optimization without avoidable delay, fracture-pattern–appropriate fixation or arthroplasty, early rehabilitation, and secondary fracture prevention. In older adults, care is defined as much by delirium, thrombotic, functional, and mortality risk as by the operation.

**Clinical question:** How should physicians coordinate diagnosis, timely surgery, perioperative optimization, rehabilitation, and secondary prevention after hip fracture?

## What matters in practice
- Hip fractures are usually low-energy fragility injuries in older adults, but young patients more often require evaluation for high-energy trauma mechanisms. [5][22][23]
- Avoid medically unnecessary surgical delay: observational data identified waiting longer than 24 hours as a threshold associated with increased 30-day mortality risk; 30-day mortality was 7.0% overall. [2]
- AAOS-supported implant selection is fracture-pattern dependent: cephalomedullary fixation is strongly supported for subtrochanteric and reverse-obliquity fractures. [16]
- Hip fracture should trigger coordinated geriatric, rehabilitation, falls-risk, and osteoporosis evaluation because major long-term functional loss, institutionalization, and excess 1-year mortality are common. [21][22]

## Treat suspected hip fracture as a time-sensitive geriatric emergency

The first priorities are confirmation, analgesia, risk assessment, and preparation for definitive surgery.

Hip fracture predominantly affects older adults after a fall from standing height in the setting of osteoporosis or osteopenia, although fractures also occur after high-energy trauma in younger patients. [5][22][23] The immediate clinical task is not solely fracture identification: assess physiologic reserve, baseline mobility and cognition, anticoagulation and coagulopathy, anemia, renal function, and acute reversible illness that could materially alter anesthetic or surgical safety. [22][24]

Most patients require operative management. [5][22] Avoid broad, low-yield preoperative testing or medication changes that defer surgery without correcting an actionable problem. In a large observational study, surgery delayed beyond 24 hours was associated with increased 30-day mortality risk; overall 30-day mortality was 7.0%. [2] Timing must nevertheless be individualized when active instability or a correctable condition requires treatment.
- Obtain admission testing sufficient to identify anemia, renal dysfunction, and coagulation abnormalities; perform type and crossmatch because hip-fracture surgery can entail substantial blood loss. [22]
- Engage orthopedics, anesthesia, nursing, physical and occupational therapy, and geriatric or medical comanagement early; geriatric input is relevant before and after surgery for optimization, comorbidity management, falls assessment, osteoporosis evaluation, and rehabilitation planning. [22]
- Document prefracture residence, ambulatory status, assistive-device use, cognitive baseline, and goals of care, because these determine realistic operative, rehabilitation, and discharge goals. [17][21]

*Immediate decision domains in hip fracture care. [2][22][24]*

| Domain | Actionable focus | Clinical consequence |
| --- | --- | --- |
| Medical readiness | Assess anemia, renal function, coagulation status, and acute comorbidity; type and crossmatch. [22] | Identifies correctable operative and anesthetic risks without substituting routine optimization for timely surgery. [2][22] |
| Medication review | For ACE inhibitor or ARB therapy used only for essential hypertension, consider withholding during the 24 hours before surgery to reduce perioperative hypotension; weigh continuation individually in chronic heart failure. [24] | Reduces hypotension risk while avoiding indiscriminate interruption of heart-failure therapy. [24] |
| Beta-blockers | Do not initiate beta-blockers immediately before surgery in patients not already receiving them; continue chronic beta-blockade for systolic heart failure unless decompensation is present. [24] | Avoids immediate preoperative bradycardia and hypotension while preserving indicated chronic therapy. [24] |
| Surgical timing | Expedite definitive surgery once medically appropriate. [2][10][20] | Delay beyond 24 hours was associated with increased 30-day mortality in observational data. [2] |

## Match the operation to fracture location, stability, and patient factors

Fracture morphology and displacement determine the principal fixation-versus-arthroplasty decision.

Hip fractures encompass intracapsular femoral-neck fractures, intertrochanteric fractures, and subtrochanteric fractures. [22][23] Femoral-neck displacement carries particular relevance because femoral-head blood supply courses along the neck; this concern is especially consequential in displaced fractures and in younger patients. [23] Surgical planning should integrate fracture pattern, displacement, physiologic status, preinjury function, and expected capacity for postoperative rehabilitation.

For subtrochanteric and reverse-obliquity fractures, AAOS guidance reports strong evidence supporting a cephalomedullary device. [16] The supplied evidence does not provide sufficient detail to support a specific device, implant, or postoperative weight-bearing prescription for every other fracture pattern; use current institutional orthopedic protocols and the complete contemporary guideline for these decisions.
- Intracapsular femoral-neck injury: prioritize orthopedic assessment of displacement, patient age, and concern for femoral-head vascular compromise. [23]
- Intertrochanteric injury: define stability and operative fixation strategy with orthopedics; the available sources do not support more granular implant recommendations. [16][22]
- Subtrochanteric or reverse-obliquity injury: use cephalomedullary fixation unless patient-specific anatomy or surgical considerations dictate otherwise. [16]

### Preoperative optimization without harmful delay

Medical optimization should target reversible conditions rather than pursue routine normalization of chronic disease. Enhanced-recovery principles described for acute hip fracture include minimizing catabolic fasting, reducing opioid exposure when feasible, and using regional anesthesia when possible. [24] Clear carbohydrate drinks up to 2 hours before surgery are described in this review as a strategy associated with less delirium and acute kidney injury, but local anesthesia and fasting policies should govern implementation. [24]
- Do not newly start beta-blockers in the immediate preoperative period. [24]
- Recognize that perioperative myocardial infarction may lack typical chest pain or ST-segment elevation; manage identified events using a guideline-directed non-ST-elevation myocardial infarction approach. [24]

*Fracture-pattern considerations supported by available sources. [16][22][23]*

| Pattern | Key decision issue | Supported management point |
| --- | --- | --- |
| Femoral neck | Intracapsular location and displacement affect concern for femoral-head vascular injury. [23] | Use orthopedic assessment to guide fixation versus arthroplasty planning; no specific selection rule is supported by the supplied results. [23] |
| Intertrochanteric | Assess stability and fixation requirements. [16][22] | The supplied evidence supports operative management broadly but does not provide a granular implant recommendation. [5][16][22] |
| Subtrochanteric or reverse obliquity | Mechanical instability requires durable fixation. [16] | Cephalomedullary device is strongly supported by AAOS evidence. [16] |

## Prevent immobility-related complications and mobilize through multidisciplinary care

Postoperative care should be organized around mobility restoration, delirium avoidance, complication surveillance, and discharge readiness.

Recovery requires more than technically successful fixation or arthroplasty. Rehabilitation guidance emphasizes multidisciplinary management, physical and occupational therapy, management of comorbidities and complications, and planning for community-based rehabilitation after intensive treatment. [17] Rehabilitation goals include restoration of mobility and physical function, improvement in quality of life, and reduction of refracture and mortality risk. [17]

Pain, venous thrombosis, urinary tract infection, osteoporosis, and nutrition are recognized post-fracture rehabilitation issues. [17] The supplied sources do not provide enough evidence to specify an analgesic regimen, venous thromboembolism prophylaxis drug, dose, duration, or universal mobilization timeline; apply current institution-specific orthopedic, anesthesia, and thromboprophylaxis protocols.
- Use multidisciplinary rounds to identify pain limiting participation, delirium or cognitive change, infection, urinary complications, nutritional barriers, and functional obstacles to transfer and ambulation. [17][22]
- Begin discharge planning early because rehabilitation setting should reflect functional deficits, comorbidity burden, rehabilitation needs, and available support services. [21]
- Communicate expected outcomes explicitly: hip fracture is associated with impaired ambulation, institutionalization in at least one-third of survivors in some studies, and excess 1-year mortality of 12% to 25%. [21]

*Postoperative domains requiring active coordination. [17][21][22]*

| Domain | What to assess | Why it matters |
| --- | --- | --- |
| Function | Prefracture mobility, transfer ability, self-care capacity, and therapy progress. [17][21] | Determines rehabilitation intensity, destination, and needed caregiver support. [21] |
| Medical complications | Pain, venous thrombosis, urinary tract infection, nutrition, and comorbidity management. [17] | These can delay recovery and reduce functional gains. [17] |
| Cognition and delirium risk | Baseline cognition and postoperative mental-status changes. [24] | Delirium prevention is a component of enhanced-recovery approaches. [24] |
| Secondary prevention | Falls risk and osteoporosis evaluation before transition from fracture care. [22] | A hip fracture identifies a patient at high risk for future skeletal morbidity. [12][13][22] |

## Use hip fracture as a mandatory secondary prevention trigger

The fracture episode should close with a documented plan for bone health and recurrent-fall risk.

A hip fracture should prompt osteoporosis assessment and treatment planning rather than deferral to an unspecified outpatient visit. Geriatric involvement is specifically relevant to osteoporosis investigation and falls-risk assessment during recovery. [22] In men aged 50 years or older, Endocrine Society guidance recommends pharmacologic treatment after a hip or spine fracture, independent of bone mineral density, and also recommends treatment for a T-score of −2.5 or lower or high fracture risk. [13]

U.S. observational data have documented low osteoporosis medication treatment rates after hip fracture, despite the position that affected patients should be considered for FDA-approved osteoporosis medication. [12] The supplied search results do not provide medication-specific selection criteria, doses, renal thresholds, sequencing, or monitoring; avoid prescribing details beyond current labeling and comprehensive osteoporosis guidance.
- Before discharge or transfer, assign ownership for osteoporosis evaluation, pharmacotherapy decision-making, and falls-risk intervention. [12][22]
- For men aged 50 years or older with hip fracture, pharmacologic osteoporosis treatment is guideline-supported. [13]
- Review prior antiresorptive exposure and new thigh or groin pain when clinically relevant: atypical femoral fractures have been reported with anti-osteoporosis therapies, including bisphosphonates and denosumab, but adverse-event reporting cannot establish comparative causality or incidence. [8]

*Secondary prevention actions after hip fracture. [12][13][22]*

| Action | Evidence-supported rationale | Implementation limitation |
| --- | --- | --- |
| Osteoporosis assessment | Hip-fracture care should include evaluation for osteoporosis and calcium abnormalities. [22] | Specific laboratory and imaging protocols are not defined in the supplied sources. [22] |
| Pharmacotherapy decision | Patients with hip fracture should be considered for FDA-approved osteoporosis medication; men aged 50 years or older with hip fracture meet Endocrine Society treatment criteria. [12][13] | Agent selection and dosing require current drug labeling and osteoporosis guidance not supplied here. [12][13] |
| Falls-risk assessment | Geriatric medicine involvement includes assessment of falls risk. [22] | The supplied sources do not specify a validated fall-risk instrument or intervention bundle. [22] |

## Frame prognosis around survival, mobility, and living independence

Prognosis should guide goals-of-care discussions, rehabilitation planning, and caregiver counseling.

Hip fracture carries substantial short- and long-term risk. In a large cohort evaluating surgical wait time, 30-day mortality was 7.0%. [2] Earlier U.S. effectiveness-research synthesis reported excess 1-year mortality of 12% to 25%, impaired ambulation, and institutionalization in 33% or more of survivors; some studies reported long-term care needs in as many as 50% of patients. [21] These estimates should support honest counseling but should not replace individualized prognostication based on baseline function, cognition, comorbidity, fracture pattern, perioperative course, and rehabilitation response.

The most useful communication is functional: establish whether the expected goal is restoration of prior community mobility, transfer-level independence, limited ambulation, or comfort-focused care. Rehabilitation needs and setting depend on the number of problems to address, severity of functional deficits, severity of comorbid conditions, and access to alternative services. [21]
- Discuss likely discharge needs with patients and caregivers early, particularly when prefracture function or cognition was limited. [21]
- Use survival estimates as population-level context, not as a reason to delay indicated rehabilitation, secondary prevention, or shared decision-making. [2][21]

*Outcome data useful for prognostic discussions. [2][21]*

| Outcome | Reported estimate | Interpretation |
| --- | --- | --- |
| 30-day mortality | 7.0% overall in a cohort of adults undergoing hip-fracture surgery. [2] | Short-term mortality is clinically material and may rise with surgical delay beyond 24 hours. [2] |
| Excess 1-year mortality | 12% to 25%. [21] | Older synthesis; use as contextual, not individualized, prognostic information. [21] |
| Institutionalization | 33% or more of survivors in some studies. [21] | Supports early discharge planning and caregiver counseling. [21] |

## Common questions

### Should hip-fracture surgery be delayed for extensive medical optimization?

Correct reversible instability and clinically meaningful acute problems, but avoid nonessential delay. Waiting longer than 24 hours was associated with increased 30-day mortality risk in observational data. [2]

### Which fracture pattern has a clear implant recommendation in the available evidence?

AAOS guidance strongly supports a cephalomedullary device for subtrochanteric or reverse-obliquity fractures. [16]

### What osteoporosis action is supported after hip fracture?

Arrange osteoporosis evaluation and treatment ownership. Hip-fracture patients should be considered for FDA-approved osteoporosis medication; men aged 50 years or older with hip fracture meet Endocrine Society treatment criteria. [12][13][22]

### What should determine rehabilitation disposition after hip fracture?

Base disposition on functional deficits, comorbidity severity, rehabilitation needs, and access to alternative support services. [21]
