• SI Joint Fusion

      Sacroiliac (SI) Procedures

    • Treatments can range from injections, sacroiliac joint belts, physical therapy or the iFuse procedure. Local Parker Adventist spine surgeon, Dr. Brad Duhon, has performed more than 100 sacroiliac fusion surgeries using the minimally invasive iFuse Implant System.
    • The iFuse procedure is a promising procedure for patients with unresolved low back symptoms related to the sacroiliac joint. This joint can become damaged either due to normal wear and tear over time or through injury. When such damage happens, it can cause significant discomfort from the lower back down to the lower buttock region and the upper leg. 
    • Sacroiliac joint pain can account for up to 30% of all lower back symptoms, but may not be included when your physician diagnoses for lower back pain. The iFuse procedure is designed to offer a minimally invasive solution for patients who are no longer responding satisfactorily to conservative care, but for whom the prospect of a traditional open surgery is not desirable.
    • The iFuse procedure takes about an hour and involves three small titanium implants inserted surgically across the sacroiliac joint. The entire process is done through a small incision, with no soft tissue stripping and minimal tendon irritation. Patients typically leave the hospital the next day after surgery and can usually resume daily living activities within six weeks, depending on how well they are healing and based on physician’s orders.
    • “SI joint dysfunction is such a widely under-diagnosed pathology, that many of these patients live in pain for years before it is finally identified” says Dr. Duhon. “Treatment, upon diagnosis, relies upon a multidisciplinary approach.  I am fortunate to work with a team of physical therapists here at Parker Adventist Hospital who are dedicated to conservative treatment of SI joint dysfunction.  In addition, our interventional pain colleagues help us to confirm diagnosis and also provide non-surgical therapeutic options.  Finally, only when those patients have truly exhausted all conservative modalities does surgery become a viable treatment option.  We have done our best here at Neurosurgical & Spine Specialists to follow the outcomes of our SI fusion patients to ensure that the procedure is not only safe, but effective as well.”
    • Congratulations to Dr. Duhon for reaching the impressive landmark of his 100th iFuse procedure. If you are experiencing lower back pain and interested in learning about your options, contact our physician referral services or visit Parker Adventist Website.

    Dr. Brad Duhon - SI Joint Dysfunction


    Parker Adventist Hospital neurosurgeon Dr. Brad Duhon, discusses sacroiliac (SI) joint dysfunction which causes back pain as well as pain in the upper buttocks and upper legs. Dr. Duhon explains how SI fusion surgery is highly effective in eliminating the pain.


    1. What are the symptoms of Sacroiliitis?
      • Pain centered in the upper buttock or very low back. It can extend into the buttock, groin, or even down the leg. Pain is worse with sitting on affected side, prolonged standing, climbing, squatting, or lying on the affected side. It can be unilateral or bilateral.
    2. How does one develop SI Joint pain?
      • Trauma (falls or car accidents most common), from pregnancy, or just from arthritis and no other cause
    3. Who else is at risk for Sacroiliitis?
      • Those who have had previous lumbar surgery. The SI joint has found to be the most common cause of pain after lumbar fusion.
    4. How is it diagnosed?
      • There are no good imaging tests to diagnose SI joint pain. It is a diagnosis suggested by history and physical examination. To confirm, an interventional pain physician must inject the SI joint with anesthetic. Dramatic relief (albeit for a brief period of time) confirms the diagnosis.
    5. What are treatment options?
      • The mainstay of treatment includes rest, anti-inflammatories, physical therapy, and chiropractor interventions. Those that fail to respond may benefit from more aggressive interventions consisting of injections, selective nerve ablation (burning) therapies, or surgical stabilization of the joint.
    6. How is it that I've had these symptoms for years but never been diagnosed?
      • This is a diagnosis that many physicians, including surgeons, often overlook. The symptoms can mimic hip or lumbar spine pathology so attention is often directed to other structures. Lately increased awareness has been given to Sacroiliitis because we feel it's incidence is increasing.
    7. What do I do if I feel I have a problem with my SI Joint?
      • Ask your doctor about it. I recommend a referral to a pain physician or spine surgeon with an interest in the SI Joint.
