PENG block to help pain after acetabular fracture surgery

Official title: Efficacy of Pericapsular Nerve Group (PENG) Block on Postoperative Pain Management After Acetabular Fracture Fixation: A Randomized Controlled Trial

Run by University of Puerto Rico · NCT07765095 · Data updated 2026-11-12

This trial tests whether giving a Pericapsular Nerve Group (PENG) block before hip socket fracture repair can lower pain and reduce opioid use after surgery.

Is this trial a fit for you?

Likely a good fit

Adults 18 years and older with an acetabular fracture suitable for Kocher-Langenbeck surgical approach and adequate weight-bearing prior to injury, able to provide informed consent.

Probably not a fit

Patients with fractures not amenable to Kocher-Langenbeck repair, bilateral acetabular fractures, or those with chronic opioid use or other exclusion criteria may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with acetabular fractures undergoing surgical fixation are randomly assigned to receive a PENG nerve block before anesthesia or no block. All participants then have standard postoperative pain care, and pain relief, opioid needs, and safety are assessed. The study aims to determine if the PENG block improves pain control and reduces opioid requirements without significant adverse effects. It is an interventional study conducted at a Puerto Rico medical center, led by the University of Puerto Rico.

Why it matters

Potential benefit: If successful, the PENG block could provide better postoperative pain control and lessen opioid use after acetabular fracture repair.

How similar studies have gone: Prior regional nerve blocks have shown promise for postoperative pain, but this specific PENG approach in acetabular fracture surgery is being tested for safety and efficacy.
