About this study
Official title: Comparison of Pericapsular Nerve Group Block (PENG) Versus Fascia Iliaca Compartment Block (FICB) for Hip Fracture Analgesia in Emergency Department Patients
Regional anesthesia for hip fractures has been shown to decrease rates of delirium in elderly patients with hip fractures as well as improve pain compared to systemic opioids. The Pericapsular Nerve Group (PENG) block has recently received attention as an alternative approach to femoral nerve block and Fascia Iliaca Compartment Block (FICB). The investigators seek to evaluate if there is a difference between the PENG and FICB in terms of efficacy of pain control in ED patients presenting with hip fracture. We hypothesize that the PENG block may be superior based on previous research.
Read the detailed description
Fractures of the proximal femur are a common presentation to the emergency department and are an acutely painful condition. This condition predominantly affects elderly patients who are at risk for delirium and more susceptible to the adverse effects of systemic opioids. Regional anesthesia is an recommended component of pain control for elderly patients with hip fracture. The investigators seek to compare the efficacy of pain control of the Pericapsular Nerve Group (PENG) block with the Fascia Iliaca Compartment Block (FICB).
Previous studies have suggested that the PENG block may be superior to the FICB for pain control and results in less thigh motor weakness. The investigators will compare pain control (by difference in mean VAS score at set time points), systemic opioid use (in mean morphine equivalents prior to surgery), and motor function in patients with hip fractures who receive either block in the ED.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Regional anesthesia for hip fractures has been shown to decrease rates of delirium in elderly patients with hip fractures as well as improve pain compared to systemic opioids. The Pericapsular Nerve Group (PENG) block has recently received attention as an alternative approach to femoral nerve block and Fascia Iliaca Compartment Block (FICB). The investigators seek to evaluate if there is a difference between the PENG and FICB in terms of efficacy of pain control in ED patients presenting with hip fracture. We hypothesize that the PENG block may be superior based on previous research.

Questions about this trial
What is this clinical trial studying?
A study testing PENG and FICB in people with Femoral Neck Fractures and Intertrochanteric Fractures, run by University of Virginia at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 3 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain score (time frame: 6 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05505604, which also lists 23 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2026.
