Sacral ESPB versus PENG nerve block for pain after hip hemiarthroplasty
Official title: Sacral Erector Spinae Plane Block Versus Pericapsular Nerve Group Block For Analgesia In Hip Hemi Arthroplasty: A Randomized Comparative Study
Run by Fayoum University Hospital · NCT07442721 · Data updated 2026-11-12
We will see if a sacral erector spinae plane (S-ESPB) block or a pericapsular nerve group (PENG) block gives better pain relief for adults 50–90 having hip hemiarthroplasty for a femoral neck fracture.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 50–90 with intracapsular femoral neck fractures scheduled for elective hip hemiarthroplasty and with ASA physical status I–III are the intended participants.
✕Probably not a fit
Patients with contraindications such as coagulopathy, infection at the injection site, BMI >35 kg/m2, peripheral or diabetic neuropathy, chronic opioid therapy, cognitive impairment, bilateral hip fracture, prior ipsilateral hip surgery, allergy to local anesthetics, or contraindication to spinal anesthesia are excluded and unlikely to benefit from this protocol.

What this trial studies
This is a double-blinded, randomized, parallel-group study at Fayoum University Hospital enrolling 80 patients aged 50–90 with intracapsular femoral neck fractures scheduled for elective hip hemiarthroplasty. Patients are randomized 1:1 to receive either a sacral erector spinae plane (S-ESPB) block or a pericapsular nerve group (PENG) block before surgery, with allocation concealed by opaque sealed envelopes. The patient, the data collector, and the outcome assessor are blinded to group assignment while blocks and equipment are prepared by independent personnel. Postoperative pain scores, opioid consumption, and motor function will be compared between the two groups.
Why it matters
Potential benefit: If successful, one block approach could offer better pain control with less motor impairment and lower opioid requirements after hip hemiarthroplasty.
How similar studies have gone: PENG block has clinical studies showing anterior hip analgesia but can be associated with motor weakness, while sacral ESPB currently has mainly case reports and is less well studied for hip surgery.
