Analgesia boost from adding a sacral submultifidus block to SIJ injection

Official title: Analgesic Effect of Sacral Submultifidus Block as an Adjunct to Sacroiliac Joint Injection: A Randomized Controlled Double-Blind Trial

Run by Fayoum University Hospital · NCT07814729 · Data updated 2026-11-12

This study tests whether adding a sacral submultifidus block to a standard image-guided sacroiliac joint injection provides better pain relief and function for adults with chronic SIJ‑related pain.

Is this trial a fit for you?

Likely a good fit

Adults 21 years or older with chronic SIJ pain (NPRS ≥5) and a positive diagnostic SIJ block (≥75% pain relief) who have failed conservative therapy and have no contraindications.

Probably not a fit

Some participants may not experience additional pain relief or functional improvement from the added sacral submultifidus block.

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

What this trial studies

Participants with chronic sacroiliac joint pain receive either the standard image-guided SIJ injection or the SIJ injection plus a sacral submultifidus block. The study compares analgesia and functional outcomes between the two approaches. The SIJ pain mechanism and innervation are reviewed, and eligibility requires persistent pain, positive provocative tests, and a diagnostic SIJ block response. Exclusion criteria include allergy to anesthetics, coagulation disorders, opioid abuse, and pregnancy. The study is conducted at Fayoum University Hospital in Egypt and aims to determine if the added block yields superior relief beyond SIJ injection alone.

Why it matters

Potential benefit: If successful, patients could experience greater and longer-lasting pain relief and improved function with the combination procedure.

How similar studies have gone: Prior SIJ injections show modest benefits with variability; this combination approach is being explored to enhance efficacy.
