Reducing Pain and Opioids in Hip Fracture Patients: The Role of Ultrasound-Guided Fascia Iliaca Block in the Emergency Department

Moultrie, GA

Introduction

Hip fractures are a common and serious injury in the aging population and are associated with significant morbidity and mortality, resulting from falls and age-related bone degeneration. As life expectancy increases, the number of new hip fractures worldwide is expected to exceed 6 million by 2050. Severe pain following a hip fracture is strongly associated with increased morbidity, delayed recovery, and prolonged hospitalizations, demonstrating the need for early and effective pain management strategies.

Traditionally, systemic opioids have been the primary treatment for acute hip fracture pain. However, opioid therapy is associated with several adverse effects, therefore, recent interest has focused on the use of ultrasound-guided fascia iliaca nerve blocks as an alternative for hip fracture pain. Evidence suggests that fascia iliaca nerve blocks may improve pain control, facilitate earlier mobilization, and reduce opioid requirements making them potentially safer and more effective for early pain management.

Methods

A literature review was conducted on fascia iliaca and femoral nerve blocks for hip fracture pain management in the emergency department using publications from 2015 to 2025 via PubMed, Cochrane, and major peer-reviewed medical literature. Search terms included ("fascia iliaca block" OR "femoral nerve block") AND (“emergency department" OR "emergency medicine") AND ("hip fracture"). After screening the abstracts, full-text articles were analyzed.

Inclusion criteria included adult patients with hip fractures treated in the emergency department or acute care setting, with a variety of study designs. Outcomes of interest included pain scores, opioid consumption, and complications or adverse effects.

Results

The reviewed literature consistently demonstrates that fascia iliaca compartment block (FICB) provides effective analgesia for patients presenting with hip fractures. Across randomized controlled trials, cohort studies, and meta-analyses, FICB was associated with improved early pain control and reduced opioid consumption compared with systemic analgesia alone.

Meta-analyses by Hong and Ma and Makkar et al. evaluated randomized and controlled trials of FICB for hip fracture patients treated in emergency settings, and found that FICB was associated with significantly reduced pain scores, opioid use and opioid-related adverse effects. Trial sequential analysis supported the robustness of these findings, suggesting sufficient cumulative evidence for the analgesic benefit of the intervention.

A randomized controlled trial by Chen et al. demonstrated improved perioperative pain control and decreased opioid use in patients receiving ultrasound-guided FICB during arthroplasty. Observational studies by Kolodychuk et al., Salottolo et al., and Snapp et al. reported reduced opioid use, shorter hospital stays, and reduced delirium among patients receiving fascia iliaca nerve blocks. These findings suggest that decreased opioid use may contribute to improved clinical outcomes in older adults.

Discussion

Current evidence supports ultrasound-guided FICB as an effective analgesic strategy for adults presenting to the ED with hip fractures. Compared with systemic opioids alone, FICB provides superior pain control, reduced opioid consumption, and potentially fewer opioid-related complications. Further large randomized controlled trials are needed to clarify optimal timing and long-term patient outcomes. Current evidence supports the integration of ultrasound-guided regional anesthesia into emergency departments for management of acute hip fracture pain.
