The sacroiliac joint (SI joint) is located in the pelvis; it links the iliac bones (pelvis) to the sacrum (lowest part of the spine above the tailbone). It is an essential component for shock absorption to prevent impact forces from reaching the spine.
What are the symptoms of SI Joint Dysfuction?
Like any other joint in the body, the SI joint can be injured and/or become degenerative. When this happens, people can feel pain in their buttock and sometimes in the low back and legs. This is especially true while lifting, running, walking or even sleeping on the involved side.
According to scientific data, it’s common for pain from the SI joint to feel like disc or low back pain. For this reason, SI joint disorders should always be considered in low back pain diagnosis.
- Low back pain
- Sensation of low extremity: pain, numbness, tingling, weakness
- Pelvis/buttock pain
Hip/groin pain - Feeling of leg instability (buckling, giving way)
- Disturbed sleep patterns
- Disturbed sitting patterns (unable to sit for long periods, sitting on one side)
- Pain going from sitting to standing

SI Joint Fusion with the iFuse Implant System
The sacroiliac (SI) joint is a significant cause of low back pain. Clinical publications have identified the SI joint as a pain generator in 15-30% of chronic low back pain patients. In addition, the SI joint is a pain generator in up to 43% of patients with continued or new onset low back pain after a lumbar fusion. The iFuse Implant System® manufactured by SI-BONE®, Inc. is a minimally invasive surgical SI joint treatment option that provides stabilization and fusion of the SI joint for some causes of SI joint pain. This is accomplished by inserting triangular-shaped titanium implants across the joint to maximize post-surgical stability and weight bearing capacity. The procedure is done through a small incision, usually less than two inches long and takes about an hour. Under image guidance, the doctor inserts titanium implants across the sacroiliac joint to provide stability. The procedure usually takes less than an hour and is often performed in an outpatient setting. Multiple published studies on iFuse have documented procedure safety and effectiveness. There are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit.
