TREATMENT OVERVIEW

Minimally Invasive SI Joint Fusion

Minimally Invasive Sacroiliac (SI) Joint Fusion is a surgical procedure that provides a permanent solution for chronic SI joint pain. For patients whose pain is confirmed to originate from the SI joint and has failed to respond to conservative care, this procedure stabilizes the joint by fusing it, thereby eliminating the painful motion that causes discomfort and restoring function.

Quick Facts

  • • Procedure Duration: Approximately 1 hour
  • • Recovery Time: Walking same day, gradual return to activity
  • • Pain Relief Onset: Gradual improvement as the joint fuses
  • • Success Rate: High patient satisfaction for pain reduction

PROCEDURE DETAILS

What is the Procedure?

SI Joint Fusion is a surgical procedure performed in an operating room under general anesthesia. While you are comfortably positioned face down, your surgeon will make a small incision, about one inch long, on the side of your buttock.

Using fluoroscopy (live X-ray) for continuous guidance, specialized instruments are carefully passed through the gluteal muscles to access the iliac bone. This minimally invasive approach avoids the need for large-scale muscle cutting, leading to a much faster recovery.

A channel is then prepared across the SI joint, and bone graft material is placed to encourage the bones to fuse together. Typically, three titanium implants are then inserted across the joint. These implants provide immediate stability and create the optimal environment for the bones to fuse permanently. The small incision is then closed, and you are taken to recovery.

TREATMENT ADVANTAGES

What are the Benefits?

For properly selected patients, minimally invasive SI joint fusion offers the chance to reclaim a pain-free, active life by providing a permanent solution to debilitating pain.

Permanent Pain Solution

By eliminating motion at the painful, arthritic joint, this procedure is designed to provide a lasting, permanent solution to chronic SI joint pain.

Minimally Invasive Approach

A small incision means less damage to muscle tissue, which leads to less post-operative pain, minimal scarring, and a significantly faster recovery.

High Success Rates

Clinical studies consistently show high rates of patient satisfaction, with significant and durable reductions in pain, disability, and opioid use.

Restored Stability & Function

Fusing the unstable joint restores stability to the pelvis, allowing patients to return to walking, standing, and other activities without debilitating pain.

Reduced Need for Opioids

By resolving the underlying mechanical problem, most patients are able to significantly decrease or completely stop their use of chronic pain medications.

Short Hospital Stay

Because the procedure is minimally invasive, it typically requires only a short hospital stay, with many patients going home the same or the next day.

IMPORTANT INFORMATION

What are the Risks and Side Effects?

SI Joint Fusion is a very safe and effective surgery, but as with any surgical procedure, it carries potential risks and side effects that your surgeon will discuss with you in detail.

Common Side Effects

  • Post-operative pain and soreness at the incision site
  • Bruising and swelling in the buttock area
  • Temporary difficulty walking or putting weight on the leg
  • Mild numbness around the incision

Rare Complications

  • Standard surgical risks (infection, bleeding, blood clots)
  • Nerve root injury or irritation
  • Improper healing of the fusion (nonunion)
  • Implant malposition or failure requiring revision

Important: Careful patient selection is the most critical factor for success. This procedure is only considered after your pain has been definitively diagnosed with successful SI joint injections.

PREPARATION GUIDE

How to Prepare for the Procedure?

Proper preparation for your surgery is essential for a smooth procedure and recovery. Please review the following important steps.

Review of Allergies

Ensure you have a thorough review with Dr. Fura. Disclose all allergies, especially to medications like contrast dye.

Medication Adjustments

Stop blood thinners and other specific medications as instructed by Dr. Fura before your procedure.

Fasting & Transportation

Do not eat or drink after midnight. You must arrange for a responsible adult to drive you home afterward.

Day of Procedure Attire

Wear comfortable, loose clothing. Avoid jewelry and leave valuables at home for safekeeping.

RECOVERY GUIDE

What is the Post-Procedure Care?

Your recovery is a gradual process focused on protecting the healing fusion while progressively returning to your normal activities.

First 24 Hours

After surgery, you will be monitored in recovery. A physical therapist will help you get up and walk with the assistance of crutches or a walker, often on the same day.

First Few Weeks

You will use walking aids and have restrictions on weight-bearing, bending, lifting, and twisting. The focus is on short walks and managing post-operative pain as your body begins to heal.

Weeks 6-12

Your first follow-up with X-rays will occur around 6 weeks. As healing progresses, you will be cleared to increase your activities and begin a formal physical therapy program to strengthen your core.

Full Recovery

Full fusion typically takes 3 to 6 months. Follow-up appointments will monitor your progress until you are fully healed and have returned to your desired level of activity.

When to Contact Your Doctor

  • Signs of infection (fever > 101°F, chills, drainage from incision)
  • Signs of a blood clot (calf pain and swelling, shortness of breath)
  • Severe, uncontrolled pain not helped by medication
  • New or worsening weakness or numbness in your leg
