SI Joint Fusion
 

Introduction to SI Joint Fusion

SI joint fusion is a minimally invasive surgical procedure designed to provide long term relief from chronic sacroiliac (SI) joint pain. By stabilizing and fusing the SI joint using specialized implants, this treatment reduces abnormal motion that causes inflammation and pain, allowing patients to regain stability, comfort, and improved function in their daily lives.

​

Procedure Details

Preparation:

Before the Procedure: Patients may be instructed to avoid eating for several hours prior to surgery and should arrange for someone to drive them home. Preoperative imaging and medical clearance may be required.

​

Procedure Description:

  • Positioning: Patients are positioned comfortably on the operating table to allow precise access to the SI joint.

  • Incision and Implant Placement: Using fluoroscopic (x ray) guidance, a small incision is made. Specialized instruments are used to prepare the joint, and small implants are inserted across the SI joint to stabilize and promote fusion.

  • Stabilization: The implants secure the joint, limiting painful motion and allowing bone growth over time to achieve fusion.

​

Duration:

The procedure typically takes about 45 to 90 minutes and is commonly performed on an outpatient basis, allowing patients to return home the same day.

​

Frequency:

SI joint fusion is generally performed once per affected side. Because it is designed as a long term solution, repeat procedures are uncommon unless symptoms develop on the opposite side or complications occur.

​

Expected Results:

  • Patients may experience early pain relief from stabilization of the joint.

  • Full benefits are typically realized over several months as the joint fuses and heals.

  • Many patients report significant reduction in low back and buttock pain, improved mobility, and decreased reliance on pain medications.

​

Risks and Side Effects:

  • Common Side Effects: Temporary soreness at the incision site, swelling, or mild postoperative discomfort.

  • Serious Risks: Rare risks include infection, bleeding, nerve irritation, implant migration, or failure of the joint to fully fuse.

​

Post-Treatment Care:

  • Recovery: Patients are usually encouraged to walk the same day. Activity restrictions may be recommended for several weeks to allow proper healing.

  • Follow Up: Scheduled follow up appointments and imaging help monitor healing and confirm successful fusion.

​

​

Patient Eligibility:

  • Candidacy: Ideal for patients with confirmed SI joint dysfunction who have not responded to conservative treatments such as physical therapy, medications, or injections.

  • Contraindications: Not suitable for patients with active infections, certain severe medical conditions, or those unable to undergo surgery safely.

​

Start Living an Improved Life:

With long term stabilization through SI joint fusion, patients can move forward with greater confidence and less pain. Return to the activities you enjoy without the constant limitation of SI joint instability. At Vitruvian Health, our goal is to help you achieve lasting relief and restore an active, fulfilling life.
