Quadro‑Iliac Plane Block versus Erector Spinae Plane for pain after total hip replacement
Analgesic Efficacy of Quadro-Iliac Plane Block Versus Erector Spinae Plane in Total Hip Arthroplasty: A Randomized Non-Inferiority Trial
This will test whether the quadro‑iliac plane block or the erector spinae plane block controls pain better after total hip replacement in adults having spinal anesthesia.

What this trial studies
Total hip arthroplasty is commonly performed and effective postoperative pain control is important to minimize opioid use and its side effects. This interventional comparison applies either a quadro‑iliac plane block (QIPB) or an erector spinae plane block (ESPB) after THA performed under spinal anesthesia. Participants will receive one of the two regional blocks and postoperative pain, opioid consumption, and related side effects will be monitored. The aim is to determine which block provides superior analgesia and fewer opioid-related complications for adult patients.
Who should consider this trial
Good fit: Adults aged 18 or older scheduled for elective total hip arthroplasty under spinal anesthesia with ASA physical status I–III, BMI ≤ 35 kg/m2, no opioid dependency, and no contraindications to local anesthetics.
Not a fit: Patients with allergies to local anesthetics, opioid dependency, BMI > 35, cognitive impairment, bleeding/coagulation disorders, local infection at the injection site, severe organ dysfunction, psychiatric or neurological disorders, or those undergoing emergency surgery may not benefit or be eligible.
Why it matters
Potential benefit: If successful, one block could provide better pain relief with lower opioid use and fewer opioid-related side effects after hip replacement.
How similar studies have performed: Fascial plane blocks such as ESPB and various quadratus/iliac approaches have shown opioid-sparing and pain-reducing effects in some studies, but the quadro‑iliac plane block is relatively new and direct head-to-head evidence is limited.
