Sacroiliac Fusion at our Clifton, NJ location offers Northern New Jersey patients a minimally invasive surgical solution for chronic SI joint pain that has been confirmed through careful diagnostic evaluation and has not responded to conservative care.

Chronic Lower Back and Pelvic Pain May Have a More Specific Source Than You Think

The sacroiliac joint is consistently one of the most underdiagnosed sources of chronic lower back, buttock, and pelvic pain. Its symptoms overlap closely with lumbar disc disease and radiculopathy, and many patients spend considerable time in treatment directed at the wrong target. When a thorough diagnostic evaluation confirms the SI joint as the source and conservative care has not provided lasting relief, SI Fusion offers a precise, minimally invasive path to permanent stabilization.

At Gerling Spine Care and Research Institute, Clifton patients benefit from a team that approaches SI joint dysfunction with the same diagnostic rigor and surgical precision applied across every condition we treat. Contact our Clifton office today to find out whether SI Fusion is right for you.

What Is Sacroiliac Fusion?

Sacroiliac Fusion is a minimally invasive procedure that permanently stabilizes the SI joint by placing titanium implants or bone graft material across the joint under fluoroscopic or navigation guidance.

This eliminates the painful micro-motion at the joint surface and promotes biological fusion over time, producing lasting structural stability and a significant reduction in the chronic pain and inflammation the joint was generating.

The Role of the Sacroiliac Joint

The SI joint connects the sacrum at the base of the spine to the iliac bone of the pelvis on each side of the body. Its primary function is stability rather than movement, transferring load from the upper body to the lower extremities through a dense network of surrounding ligaments. When this stability is compromised through injury, degeneration, or inflammation, the resulting pain can be severe, persistent, and easily misattributed to lumbar spine or hip pathology without a careful targeted diagnostic process.

Why Minimally Invasive Technique Matters

The minimally invasive approach to SI fusion uses a small incision, causes significantly less tissue disruption than open surgery, results in reduced blood loss, and supports a faster and more comfortable recovery. Most patients are ambulatory within 24 hours and discharged within one to two days of the procedure.

Conditions Treated With SI Fusion

SI Fusion is considered when the sacroiliac joint has been confirmed as the primary pain generator and conservative care has not produced lasting relief. Appropriate conditions include:

Sacroiliac joint dysfunction or instability
Sacroiliitis from degenerative or inflammatory causes
Degenerative arthritis of the SI joint
Post-traumatic SI joint injury or disruption
Post-partum SI joint instability
Adjacent segment stress following lumbar fusion at L5-S1
Chronic SI joint pain confirmed through diagnostic injection that has not responded to therapeutic injections

Are You a Candidate for SI Fusion in Clifton?

Good candidates have chronic lower back, buttock, or pelvic pain lasting six months or more, confirmed as originating from the SI joint through diagnostic injection, that has not responded adequately to physical therapy, anti-inflammatory medications, and therapeutic SI joint injections.

Overall health, the specific cause of SI joint dysfunction, and the absence of other significant pain generators all factor into candidacy. Our Clifton team conducts a thorough evaluation before recommending surgical intervention, and will not proceed to fusion without the diagnostic foundation that gives the procedure its best chance of producing meaningful and lasting relief.

What to Expect From SI Fusion in Clifton

From your first appointment through your full recovery, our team provides individualized guidance and support at every stage of your care.

Before Your Sacroiliac Fusion

Your consultation will include a detailed review of your symptoms, imaging, and prior treatments, including all prior injection history. Diagnostic SI joint injections are used to confirm the joint as the pain source before any surgical recommendation is made. Our team ensures every patient is fully informed and prepared before any decision is made.

The Day of Your Surgery

The procedure is minimally invasive and typically completed in under an hour. A small incision is made, and implants are placed across the SI joint under fluoroscopic or navigation guidance. Most Clifton patients are ambulatory the following day and discharged within one to two days.

Recovering After Your Procedure

Most patients notice meaningful improvement in pain within the first few weeks as stabilization reduces the micro-motion responsible for their symptoms. Full biological fusion of the SI joint, confirmed by imaging, typically takes six to twelve months. Physical therapy begins several weeks after surgery, focused on core stability and lower extremity strengthening. Our team monitors your progress closely and remains actively involved throughout recovery.

Why Choose Gerling Spine Care and Research Institute?

SI joint dysfunction is a condition that rewards careful diagnosis and precise surgical technique in equal measure. Our Clifton team brings both, alongside the broader spine and joint expertise of a practice that treats the full spectrum of conditions producing lower back and pelvic pain.

For Northern New Jersey patients who have spent months or years searching for the true source of their pain, our commitment to diagnostic rigor before any surgical recommendation sets us apart from practices that treat based on assumptions rather than confirmed findings.

Sacroiliac Fusion (SI Fusion) Frequently Asked Questions

How do I know if my pain is coming from the SI joint?

SI joint pain is typically felt just below the beltline on one side, worsens with prolonged sitting or transitional movements, and does not follow a clear nerve root pattern into the leg. A guided diagnostic SI joint injection is the most reliable confirmation of the SI joint as the pain source, and our Clifton team uses it as a central part of the diagnostic process before any treatment recommendation is made.

How is SI fusion different from spinal fusion?

Both procedures join two bones together using implants and bone grafts, but SI fusion targets the joint between the sacrum and the iliac bone rather than the vertebrae of the spine. The surgical approach, implant system, and recovery profile are distinct from those of lumbar spinal fusion.

Will SI fusion limit my movement?

The SI joint has a very limited natural range of motion, so fusion has minimal impact on overall mobility for the vast majority of patients. The goal is to eliminate the painful micro-motion at the joint while preserving normal walking, sitting, and standing function.

What if my SI joint injections have not provided lasting relief?

Short-term relief from a diagnostic injection that confirms the SI joint as the pain source, even when that relief did not last, is a meaningful indicator of surgical candidacy. Patients with confirmed SI joint pain who have not achieved lasting therapeutic benefit from injections are often well-suited for surgical stabilization, and our team will review your full injection history as part of the evaluation.

How successful is minimally invasive SI fusion?

Research consistently shows that approximately 80% of appropriately selected patients achieve meaningful and lasting pain relief following minimally invasive SI fusion. Outcomes are strongest when the SI joint has been carefully confirmed as the primary pain generator and the procedure is performed by an experienced surgical team with a systematic approach to patient selection.
