How does sacroiliac fusion work?

Sacroiliac fusion works by stabilizing the SI joint to eliminate abnormal movement that causes inflammation and pain. A specialized implant is placed across the joint, reducing motion and promoting long-term bone fusion. We use the IntraX system for sacroiliac joint fusion in Huntington. It is a minimally invasive SI joint fusion technology designed for precise implant placement with minimal disruption to surrounding tissue. Its design allows for strong stabilization while supporting natural bone growth around the implant for durable results.

What can I expect after the procedure?

Most patients experience some soreness initially, followed by gradual improvement as inflammation decreases and the joint stabilizes. Activity can be gradually increased over several weeks, and many patients report meaningful pain reduction within a few months.

Are there alternatives to sacroiliac fusion?

Yes. Conservative options include physical therapy, anti-inflammatory medications, bracing, and SI joint injections. Radiofrequency ablation may also provide temporary relief. Fusion is typically considered only after these measures fail.

When is SI fusion most often recommended?

At North Shore, we recommend SI joint fusion in Huntington when diagnostic injections confirm the SI joint as the pain source and when nonsurgical treatments no longer provide adequate or lasting relief.

Dr Ocasio is the best Dr. I have seen. He listens to you & explains everything. He's not one for putting his head in the computer & not making eye contact.
