Supra-inguinal fascia iliaca nerve block for pain after hip replacement

Official title: Supra Inguinal Fascia Iliaca Block as Rescue Analgesia Following Total Hip Arthroplasty

Run by Institut Mutualiste Montsouris · NCT06982625 · Data updated 2026-11-12

This project will try a supra-inguinal fascia iliaca nerve block during primary total hip replacement to see if it reduces pain and the need for opioids afterward.

Is this trial a fit for you?

Likely a good fit

Adults scheduled for a primary total hip arthroplasty under general anesthesia who can give written informed consent and have no contraindication to ropivacaine are eligible.

Probably not a fit

Patients who have surgical complications that prevent weight-bearing or walking, those without significant postoperative pain, or those allergic to local anesthetics are unlikely to benefit from this intervention.

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

What this trial studies

Adults scheduled for primary total hip arthroplasty under general anesthesia are randomized to receive either an ultrasound-guided supra-inguinal fascia iliaca block with ropivacaine or a placebo injection in addition to the standard surgical and anesthetic protocol. Pain scores, opioid consumption, and recovery milestones are recorded after surgery to compare groups. Rescue analgesia is available per protocol and perioperative care follows enhanced recovery principles. The trial focuses on whether adding this regional block improves early postoperative pain control and functional recovery.

Why it matters

Potential benefit: If successful, the block could lower postoperative pain and opioid requirements and speed early rehabilitation after hip replacement.

How similar studies have gone: Regional nerve blocks have reduced pain in other orthopedic procedures, and the supra-inguinal fascia iliaca block is a newer technique with encouraging but not yet definitive results for hip arthroplasty.
