An interventional study of Pericapsular nerve group (PENG) block in Acetabular Fractures, sponsored by University of Puerto Rico. Recruiting at 1 site in Puerto Rico. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-14.
Sponsored by University of Puerto Rico · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to find out whether a Pericapsular Nerve Group (PENG) block, a type of nerve block used to control pain, can reduce pain after surgery in adults with an acetabular (hip socket) fracture who are undergoing surgical repair. The study will also evaluate the safety of the PENG block.
The main questions this study aims to answer are:
Does a PENG block reduce pain after surgery? Does a PENG block reduce the need for opioid pain medications after surgery? Are there any side effects or complications related to the PENG block? Researchers will compare patients who receive a PENG block with patients who do not receive a PENG block to determine whether the block improves pain control after surgery.
Participants will:
Be randomly assigned to receive either a PENG block or no PENG block before surgery while under general anesthesia.
Undergo surgery to repair their acetabular fracture. Receive the same standard pain medications after surgery. Be asked to rate their pain at several time points after surgery using a standard pain scale.
Have their use of pain medications, recovery, and any side effects recorded during their hospital stay and follow-up.
Exclusion Criteria:
This group includes participants who will receive the pericapsular nerve group (PENG) block after surgical intervention.
Procedure: Pericapsular nerve group (PENG) block
This group includes participants who will not receive the pericapsular nerve group (PENG) block after surgical intervention and will be considered our control group.
PENG Block is a regional block technique well documented in the literature for certain orthopedic injuries and interventions. However, the efficacy of this intervention on acetabular fracture fixation has not been well studied or addressed in previous literature.
Numeric Pain Rating Scale (NPRS)
The NPRS is an 11-point scale scored from 0-10, with " 0 " representing no pain and "10" being the most intense pain experienced. Patients verbally select a value that is most in line with the intensity of pain that they have experienced at each time point under evaluation.
Time frame: From surgery to 48 hours after surgery (12 hour Intervals)
Morphine Miligram Equivalent (MME)
MME is the total amount of an opioid drug converted to an equivalent strength of oral morphine. This measure is used to track the consumption of opioids in a standardized, uniform way.
Time frame: From surgery to 48 hours after surgery (12 hour Intervals)
Time to first opioid dose
Will measure in minutes the time that patient spent without consuming opioids before requesting their first rescue therapy (opioid) dose.
Time frame: From surgery to 48 hours after surgery (Will quantify from surgery to time of administration)
Postoperative Complications
Inpatient complications are unforeseen medical issues that arise during a hospital stay, potentially extending recovery time or requiring additional treatment.
Time frame: From surgery to 48 hours after surgery
