Quadroiliac Plane Block vs Transmuscular Quadratus Lumborum Block for Hip Replacement Pain

Official title: Quadroiliac Plane Block Versus Transmuscular Quadratus Lumborum Block for Postoperative Analgesia After Total Hip Arthroplasty: A Randomized Clinical Trial

Run by Tanta University · NCT07815145 · Data updated 2026-11-12

This study tests whether the Quadroiliac Plane Block provides better postoperative pain relief and lower opioid use than the transmuscular quadratus lumborum block after total hip arthroplasty conducted under spinal anesthesia.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–75 undergoing elective unilateral THA under spinal anesthesia, without allergy to local anesthetics or contraindications to regional blocks.

Probably not a fit

Patients with BMI >40, chronic opioid use, significant organ dysfunction, infection at the injection site, or contraindications to regional anesthesia may not benefit.

What this trial studies

This interventional study compares two ultrasound-guided regional anesthesia techniques in adults undergoing elective unilateral total hip arthroplasty with spinal anesthesia. It will look at postoperative analgesia, opioid consumption, motor function preservation, and overall recovery quality to see which block offers superior pain control and faster recovery. Participants are adults 18 to 75 with ASA I–III and no contraindications to regional anesthesia. The QIPB is a newer approach targeting hip-related sensory innervation, while the QLB blocks similar regions via a different fascial plane. The trial is conducted at Tanta University with local procedures and standard perioperative care.

Why it matters

Potential benefit: If successful, patients could experience better pain relief after hip replacement with less opioid use and quicker recovery.

How similar studies have gone: Prior studies in regional anesthesia for hip surgery suggest some blocks provide effective analgesia; this head-to-head comparison explores newer QIPB against an established technique.
