Evaluation and Management of Suspected Hip Fracture
Immediate Clinical Needs
- Ambulance transport enables essential immobilization, opioid analgesia administration, intravenous fluid therapy, and patient warming strategies that are critical for hip fracture patients 1
- Patients typically present with inability to ambulate, shortened and externally rotated affected limb, and severe pain on movement 2, 3, 4
- Hip fractures cannot be reliably diagnosed or excluded on physical examination alone, making immediate imaging essential 5, 6
Time-Sensitive Nature of Hip Fractures
- Delays in diagnosis and treatment are associated with increased cost, complication rate, length of hospital stay, and both short-term and long-term mortality 5, 6
- Surgery should occur within 24-48 hours of admission to significantly reduce mortality rates and medical complications 7, 2
Essential Emergency Department Capabilities
- Standard radiographic evaluation requires AP pelvis and cross-table lateral hip views, which are the initial imaging of choice 5, 8
- Approximately 10% of proximal femoral fractures are not identified on initial radiographs, requiring MRI without IV contrast when clinical suspicion remains high 8
- Interdisciplinary care should be provided to decrease complications and improve outcomes (strong strength of evidence, strong recommendation) 2, 3, 4
Multidisciplinary Assessment and Stabilization
- Comprehensive assessment must include chest X-ray, ECG, full blood count, clotting studies, renal function, and cognitive baseline evaluation 7
- Approximately 70% of hip fracture patients are ASA physical status 3-4 with multiple comorbidities requiring immediate medical optimization 1
Pain Management Protocols
- Pain relief should be provided before diagnostic investigations begin, with formalized analgesia protocols including regular paracetamol and cautious opioid use 1, 7
- Nerve blocks (femoral/fascia iliaca) significantly reduce acute pain and should be administered by trained emergency department staff 1, 7
- Approximately 40% of patients have moderate renal dysfunction requiring careful medication selection 1
Critical Pitfalls of Office-Based Evaluation
- Office settings lack the capability for immediate orthogonal radiographic views, IV access, continuous monitoring, and rapid surgical consultation 5, 8
- Fast-track triage systems in emergency departments enable early clinical recognition and rapid ward admission 1
Mortality Impact
Special Considerations
- Patients with negative initial radiographs but persistent clinical suspicion require advanced imaging (MRI) that is typically only available through emergency department protocols 8
- The emergency department provides essential coordination for orthogeriatric comanagement, which has been shown to have the shortest time to surgery and lowest mortality rates 7
