  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Adult (>18 y/o) males and females referred for therapeutic injection to the investigators spine interventional service by a physiatrist or pain anesthesiologist with a clinical diagnosis of SIJ pain confirmed by history
  • 50% or greater reduction in pain by a diagnostic anesthetic block using no more than 1.5 cc 2% lidocaine performed under imaging guidance by a pain interventionalist (PM\&R, Pain Anesthesia, or Neuroradiology Spine Intervention).
  • Baseline pain must be >/=4 by numeric rating scale (NRS), at least 6 weeks in chronicity, and must not be multi-factorial (related to radiculopathy or axial pain localizing elsewhere) by physical examination or confounding medical history (infection, inflammatory spondyloarthropathy, or osseous metastatic disease).

About this study

Official title: Treatment for Sacroiliac Joint Pain Using Platelet-rich Plasma (PRP) Regenerative Therapy: A Randomized Controlled Trial in Comparison With Steroid/Anesthetic Injection With Advanced MR Analysis

The purpose of this study is to determine if platelet-rich plasma is superior to steroid/anesthetic for the treatment of sacroiliac joint pain.

Read the detailed description

All patients with sacroiliac joint pain diagnosed by a back pain specialist will undergo physical examination maneuvers and a test lidocaine injection of the joint. Patients who meet eligibility requirements will be randomized in a single-blind randomized controlled manner with a 50% chance of receiving platelet-rich plasma versus steroid/anesthetic injection of the sacroiliac joint(s).

Being tested
Sacroiliac intra-articular injection
Medical subject headings
Low Back Pain

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sacroiliac intra-articular injectionProcedure or surgery

    CT guided injection of platelet-rich plasma versus steroid/anesthetic into the sacroiliac joint

Platelet-rich PlasmaExperimentalPatients will receive an intra-articular injection 3 mL of autologous platelet-rich plasma in the sacroiliac joint.
Receives: Procedure: Sacroiliac intra-articular injection
Steroid/AnestheticActive comparatorPatients will receive an intra-articular injection 40 mg Depo-medrol mixed with 2 mL 0.25% bupivicaine in the sacroiliac joint.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Numeric Rating Scale

    Validated pain scale rating pain on a scale of 0 through 10. 0 for no pain, and 10 for the highest pain the patient can imagine.

    Measured: Change between baseline and 3-months post-intervention

Secondary outcomes (4)
  1. Modified Oswestry Disability Questionnaire

    Validated questionnaire used to evaluate function in patients with low back pain. The final score/index ranges from 0-100. A score of 0-20 reflects minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled, and 81-100 bed-bound.

    Measured: Change between baseline and 3-months post-intervention

  2. Short-Form 12 Survey

    Validated survey used to evaluate function in patients with low back pain. Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning.

    Measured: Change between baseline and 3-months post-intervention

  3. Functional testing

    2 validated tests for low back pain "get up and go," "5 time sit to stand." Shorter times indicate better physical function, and longer times indicate poorer physical function.

    Measured: Change between baseline and 3-months post-intervention

  4. Opiate/pain medication usage questionnaire

    Questionnaire on type, dose, and frequency of pain medications being used by the patient. All opiates will be converted to the morphine milligram equivalent scale with lower values indicating lower opiate content and higher values indicating higher opiate content

    Measured: Change between baseline and 3-months post-intervention

Questions about this trial

What is this clinical trial studying?

A study testing Sacroiliac intra-articular injection in people with Low Back Pain and Sacroiliac Joint Synovitis, run by University of Utah at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Numeric Rating Scale (time frame: Change between baseline and 3-months post-intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Apr 2026.
