SI JOINT FUSION
Learn About Sacroiliac (SI) Joint Fusion
Sacroiliac (SI) joint fusion immobilizes the large bones and bone fragments of the pelvis. This is completed through a minimally invasive approach.
Common Causes and Symptoms
For conditions including degenerative sacroiliitis and sacroiliac joint disruptions, sacroiliac joint fusion may be an option.
Symptoms may seem like lower back pain and it may be felt while sitting or lying down. This pain may increase when climbing hills or stairs. In addition to a dull ache, pain may be felt in the groin, thigh, or buttocks. An exam, SI joint provocation tests, and SI joint injections should be used to determine if the SI joint is the primary pain generator.
Depending on the pathology, a SI joint fusion may be an option when non-surgical techniques do not relieve symptoms. Primary goals are to provide relief of symptoms by stabilizing the sacroiliac joint.
Speak with your doctor if you are experiencing symptoms or for more information.

There are possible risks involved with any surgical procedure. Reasonable expectations and compliance with the surgeon’s pre and post-operative instructions are vital. All aspects of any potential surgery should be thoroughly discussed with your healthcare provider.
Risks associated with SI joint fusion procedures include:
- General adverse effects related to surgical procedures, such as bleeding, infection, blood clots, or allergic reactions
- Failure of adequate fusion to occur
- Local injury to the pelvis
It is important to discuss these and all other aspects of any potential surgery with your physician.

Frequently Asked Questions
Below are answers to some frequently asked questions for this procedure.
What is a spinal cage?
A spinal cage, also known as an interbody, is used in procedures that remove intervertebral discs from the spine. The cage is placed in the disc space to help fuse the spine for stability and/or to restore curvature of the spine. The shape of the cage differs based on the procedure and location on the spine.

What are spine biologics?
Spine biologics provide mechanisms for bone growth. They help in the healing and fusion process during spine surgeries and may include scaffold, signaling, or cell elements for bone formation. Click here to learn more about the types of spine biologics.
What is the difference between PEEK and 3D printed implants?
Poly-ether-ether-ketone (PEEK) implants are comprised of a synthetic material that is “bioinert”, meaning it does not interact when introduced to biological tissue. 3D printed implants are comprised of titanium alloy (Ti-6AL-4V ELI) and are created through additive manufacturing.
