What Is a Sacroiliac Joint Fusion Procedure and How Does It Work?

A sacroiliac joint fusion procedure is a minimally invasive procedure used to treat chronic sacroiliac joint pain caused by sacroiliac joint dysfunction. The sacroiliac joint, often referred to as the SI joint, connects the sacrum and ilium, linking the spine to the pelvis. Because the body has two SI joints, dysfunction in one or both can lead to significant pain and reduced stability.

During sacroiliac joint fusion, a small incision is made and titanium implants are carefully placed across the joint. These implants help stabilize the joint and encourage joint fusion between the two bones, limiting excessive movement that contributes to inflammation and pain. By stabilizing the affected area, many patients experience meaningful pain relief and improved quality of life.

Does Sacroiliac Joint Fusion Treat SI Joint Pain?

Yes. SI joint fusion is a treatment option for patients experiencing chronic low back pain, pelvic pain, or pain that radiates into the hips, buttocks, groin, or legs. Sacroiliac joint pain may develop due to injury, arthritis, degenerative sacroiliitis, pregnancy-related changes, or joint instability.

Most patients begin with non-surgical treatment options, such as physical therapy, medications, SI joint injections, steroid injections, nerve blocks, or radiofrequency ablation. When these conservative treatments no longer provide adequate relief and pain becomes persistent or increases over time, a sacroiliac joint fusion procedure in Dripping Springs may be considered as a longer-term solution.

What to Expect from the Sacroiliac Joint Fusion Procedure

The SI joint fusion procedure is typically an outpatient procedure performed at a surgery center. It usually takes about an hour and is performed using mild sedation and a local anesthetic.

Because this is a minimally-invasive approach, the procedure involves a small incision, minimal disruption to surrounding tissue, and reduced recovery demands compared to traditional surgery. Most patients are able to begin walking shortly after the procedure, with post-procedure instructions tailored to their individual treatment plan.

Risks of the SI Joint Fusion Procedure

Sacroiliac joint fusion is generally considered a low-risk procedure, but as with any surgery, potential complications exist. These may include:

  • Infection at the procedure site
  • Bleeding
  • Injury to the surrounding nerves or tissue
  • Adverse reactions to medications or anesthesia

In rare cases, additional intervention or revision surgery may be required. All risks, including recovery expectations and potential outcomes, are reviewed in detail during your thorough evaluation with your pain management provider.

Frequently Asked Questions

Can sacroiliac SI joint dysfunction cause acute or radiating pain?

arrow icon

Yes. Sacroiliac SI joint dysfunction can cause acute pain as well as radiating pain that travels through the lower back, buttocks, hips, groin, or legs. In some cases, patients may also experience discomfort that affects posture and movement patterns throughout the upper body, as the spine and pelvis work together to maintain balance and stability.

Why does SI joint pain sometimes worsen over time?

arrow icon

Without proper treatment, SI joint dysfunction may lead to increased pain due to ongoing inflammation, joint instability, or compensatory stress on surrounding muscles and joints. As symptoms progress, pain may interfere more significantly with daily activities, making early evaluation and a personalized treatment plan important for long-term relief.

Is the SI Joint Fusion Procedure Covered by Insurance?
