The sacroiliac (SI) joint is located between the sacrum (the triangular bone at the base of the spine) and the iliac bones (the pelvis). This joint helps to stabilize the pelvis, bear the upper body’s weight, and absorb the impact of movements such as walking or lifting. However, the SI joint can sometimes become a source of chronic pain due to conditions like arthritis, trauma, or dysfunction.
What is SI Joint Fusion?
SI joint fusion is a minimally invasive surgical procedure that stabilizes the sacroiliac joint by “fusing” it. During the procedure, small implants are placed to prevent the bones in the joint from moving against each other, reducing pain. This procedure is usually considered for patients who have not responded to other treatments, such as physical therapy, pain medications, or steroid injections, and continue to experience pain due to SI joint dysfunction.
What Does SI Joint Fusion Treat?
SI joint fusion can help with:
Patients who undergo this procedure often report a significant reduction in pain, improved mobility, and a better quality of life.
Procedure Steps
You’ll be given specific instructions on how to prepare for the procedure, which may include fasting before surgery and adjusting certain medications. The procedure is generally done in an outpatient surgical setting.
The procedure is usually performed under general anesthesia or spinal anesthesia, depending on what’s best for your specific case.
A small incision (about 1-2 inches) is made along the lower back, over the SI joint. Using imaging guidance (X-ray or CT), specialized instruments are inserted through the incision to place small implants across the SI joint.
The surgeon inserts one or more titanium or other specialized implants to stabilize the joint. These implants encourage bone growth across the joint, promoting long-term fusion and stability.
The incision is closed, and a dressing is applied. The entire procedure typically takes about one to two hours.
After the Procedure: When Can I Go Home?
Since SI joint fusion is minimally invasive, most patients can go home the same day or within 24 hours. You’ll be monitored for a few hours after the procedure, and once you’re comfortable, you’ll be discharged with specific post-operative instructions.
Post-Operative Care
How Many Procedures Are Needed to See Pain Relief?
SI joint fusion is generally a one-time procedure designed to provide long-term relief. Patients typically notice a reduction in pain within the first few weeks to months following surgery, with full effects seen as the fusion matures. In some cases, additional interventions might be considered if full relief isn’t achieved, though repeat fusions are uncommon.
Final Thoughts
While individual results vary, studies have shown that most patients experience significant pain relief, improved function, and greater stability after SI joint fusion. Some patients may experience full relief, while others report partial but meaningful pain reduction.
