iFuse Implant System
Dr. David Paulson is now trained in the novel minimally invasive surgical technique called iFuse Implant System® from SI-BONE®, Inc., a medical device company pioneering MIS sacroiliac (SI) joint treatment. The iFuse Implant System is intended for sacroiliac joint fusion for some causes of SI joint pain. SI joint treatment using the patented triangular design of the iFuse Implant™ has produced unparalleled clinical results. More than seventy published, peer-reviewed articles demonstrate safety and effectiveness of the iFuse Implant System.
Do You Have SI Joint Problems or Sacroiliac Pain?
The SI joint is a significant cause of lower back pain. Clinical publications have identified the SI joint as a pain generator in 15-30% of chronic lower back pain patients. In addition, the SI joint is a pain generator in up to 43% of patients with continued or new onset lower back pain after a lumbar fusion.
​
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 lower 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 lower back pain. For this reason, SI joint disorders should always be considered in lower back pain diagnosis.

Making a Diagnosis
A variety of tests performed during physical examination may help reveal the SI joint as the cause of your symptoms. Sometimes, X-rays, CT-scan or MRI may be helpful in the diagnosis of SI joint-related problems.
​
The most relied upon method to accurately determine whether the SI joint is the cause of your lower back pain symptoms is to inject the SI joint with a local anesthetic. The injection will be delivered under either X-ray or CT guidance to verify accurate placement of the needle in the SI joint. If your symptoms are decreased by at least 50%, it can be concluded that the SI joint is either the source of or a major contributor to your lower back pain.
​
If the level of pain does not change after SI joint injection, it is less likely that the SI joint is the cause of your lower back pain.
Treatment Options
Once the SI joint is confirmed as the cause of your symptoms, treatment can begin. Some patients respond to physical therapy, use of oral medications, or injection therapy. These treatments are often performed repetitively, and frequently symptom improvement using these therapies is temporary. At this point, you and your surgeon may consider other options, including minimally invasive surgery and SI Fusion.
