Still Hurting After Spinal Fusion? Your SI Joint May Be the Reason
Spinal fusion surgery is meant to bring relief, and for many people it does. But a surprising number of patients find that pain continues, or even starts in a new place, after their fusion has healed. If your lower back, buttocks, or upper legs still ache months after surgery, the sacroiliac joint (SI joint) may be responsible. SI joint problems are one of the most commonly identified causes of persistent pain after spinal surgery, and they often respond well to a targeted, minimally invasive treatment called an SI joint injection.

What the SI Joint Is and Why Fusion Can Affect It
The sacroiliac joint sits where your sacrum (the triangular bone at the base of your spine) meets your ilium (the large wing-shaped hip bone) on each side of your pelvis. You have one on each side, and together they carry the weight of your upper body and absorb shock when you walk, stand, or climb stairs.
When a lumbar spinal fusion is performed, the vertebrae above the SI joint are permanently joined together. That’s the whole point of the surgery. But fusing those segments changes how forces move through your lower back. The SI joint can end up absorbing more stress than it did before. Over time, that extra load may cause inflammation (swelling and irritation inside the joint), cartilage wear, and real pain. According to research cited by the Mayo Clinic, SI joint dysfunction is estimated to account for up to 25% of lower back pain cases, and the risk is meaningfully higher in patients who have had lumbar fusion surgery.
The pain usually shows up in the lower back, one or both buttocks, or the back of the thigh. It gets worse when you stand up from sitting, climb stairs, or lie on the affected side. Sound familiar?
What an SI Joint Injection Involves and May Offer
An SI joint injection is a targeted outpatient procedure designed to deliver medication directly into the joint space with image guidance. Here’s what the procedure involves and what it may offer:
- Precise delivery: A corticosteroid (a powerful anti-inflammatory medication) and a local anesthetic are injected directly into the SI joint, guided by fluoroscopy (real-time X-ray) or ultrasound so the physician can confirm accurate placement.
- Potential pain reduction: The injection may help reduce inflammation inside the joint, which can lead to meaningful relief for some patients, though results vary.
- Diagnostic value: If your pain significantly decreases within the first hour after the anesthetic takes effect, that response strongly suggests the SI joint is contributing to your pain, which helps guide future treatment decisions.
- Short procedure time: The injection itself often takes about 15 to 30 minutes, and most patients go home the same day.
- Non-surgical approach: It’s a minimally invasive option that doesn’t require general anesthesia or an overnight hospital stay.

The clinic is conveniently located near I-20 and State Highway 360, making it easy to reach from Arlington, Irving, and the surrounding Mid-Cities.
Who May Be a Good Candidate for This Procedure?
Not every patient with post-fusion pain is automatically a candidate for an SI joint injection. An individualized evaluation is always the right starting point. Generally speaking, candidates often share several of these characteristics:
- Confirmed SI joint involvement: Pain that’s consistent with SI joint dysfunction based on physical exam findings and movement tests.
- Failed conservative measures: Symptoms that haven’t responded adequately to rest, over-the-counter anti-inflammatory medications, or physical therapy for the spine.
- Post-fusion pain pattern: New or worsening lower back, buttock, or thigh pain that developed after lumbar spinal fusion surgery.
- No contraindications: No active infection at the injection site, no bleeding disorders, and no allergies to the medications used.
Who This Procedure May Not Be Ideal For
Honest information matters when you’re making a treatment decision. SI joint injections aren’t generally recommended for patients with active systemic infection, those who are pregnant, or patients whose imaging and clinical findings point clearly to a different pain source. Your physician will review your spinal fusion imaging, your full medical history, and your current symptoms before recommending this or any other procedure. If the SI joint isn’t the primary driver of your pain, there are other injection and nerve block options that may be more appropriate.
How the Procedure Typically Works: What to Expect on Appointment Day
Walking into a procedure room can feel intimidating, especially after you’ve already been through spinal surgery. Here’s a realistic, step-by-step picture of what a typical SI joint injection appointment looks like at an interventional pain clinic.
What to Expect During Recovery
Recovery from an SI joint injection is generally straightforward compared to surgical recovery. Most people can return to light daily activities within 24 to 48 hours. You may notice some temporary soreness at the injection site, which typically fades within a day or two.
The local anesthetic often provides quick, short-term relief within the first few hours. The corticosteroid, which is the longer-acting component, typically takes a few days to begin working. If the injection is going to provide meaningful relief, many patients report noticing a difference within one to two weeks.

Comparing Your Options: SI Joint Injection vs. Conservative Care
Understanding how an SI joint injection fits into the broader treatment landscape helps you have a more productive conversation with your physician. The table below offers a general comparison. Individual circumstances vary significantly, and your care team will always recommend the approach that makes sense for your specific situation.
| Approach | How It Works | Typical Setting | Recovery Time | Best Suited For |
|---|---|---|---|---|
| Physical therapy | Strengthens stabilizing muscles | Outpatient clinic | Ongoing, weeks to months | Mild to moderate dysfunction |
| Oral anti-inflammatories | Systemic inflammation reduction | Home or primary care | Variable | Early or mild pain |
| SI joint injection | Targeted steroid and anesthetic | Outpatient procedure room | 24-48 hours light activity | Confirmed SI joint pain, post-fusion |
| Radiofrequency ablation (RFA) | Interrupts nerve pain signals with heat | Outpatient procedure room | Several days, generally | Positive response to SI injection |
For many patients, physical therapy for the spine is a valuable companion to injection treatment, not a replacement. Strengthening the muscles around the SI joint can help maintain any relief achieved through the injection and reduce the chance of pain returning quickly.
Questions to Ask at Your Consultation
Going in prepared makes your appointment more productive. Here are some practical questions worth asking your pain specialist:
- Based on my imaging and exam, do my symptoms fit SI joint dysfunction?
- How many injections might I need, and how far apart would they be spaced?
- What should I do if I get only partial relief?
- Is radiofrequency ablation something I might benefit from if the injection helps?
- Will my insurance cover this procedure, and can the clinic help verify my benefits?
