Percutaneous Sacroiliac Fusion

Percutaneous Sacroiliac Fusion

Percutaneous sacroiliac fusion is a minimally invasive surgery to treat SI joint dysfunction.  SI joint dysfunction causes lower back, hip, pelvic, and groin pain and results from inadequate motion or inflammation in the joint . Evidence suggests that patients who have previously had a lumbar fusion, a traumatic event like an automobile accident and pregnant women have a higher risk of SI troubles.

Who Benefits

Sacroiliac joint problems begin in the lower back but can also involve the pelvis, legs, and groin. Surgery is appropriate when:

  • The pain stays mainly in the lower back but may continue radiating down the legs
  • You have pain or difficulty standing, walking, or getting up from a sitting position
  • Pain worsens when climbing stairs or walking on an incline
  • Pain is worse after prolonged sitting, standing, or sleeping in one position
  • The symptoms linger longer than a few months and don’t respond to other non-surgical treatment options

If your pain is new onset, doctors won’t immediately jump to surgery. Instead, they will recommend you try non-surgical options, including physical therapy, massage, medications, steroid shots, and more. And remember: no two patients are the same. You may get relief from one, some, all, or none of the non-surgical treatments. Also, be aware that a treatment that works now may not continue to do so.


Diagnosing SI problems is tricky because the muscles and joints in the lower pelvis are interconnected. Sometimes, SI joint difficulties are diagnosed through elimination rather than a positive diagnosis. Testing and evaluation regularly include:

  • Injections, including steroids or anesthetic is the primary diagnostic tool to confirm this diagnosis (If you experience a 50 to 75% reduction in your pain with a sacroiliac injection it confirms your SI is causing the problem.)
  • A comprehensive physical history will be taken
  • Completing a hands-on physical and neurological exam will be completed
  • Diagnostic imaging, including X-rays, MRIs, or CT scans may be ordered

Percutaneous sacroiliac fusion is, as previously stated, a minimally-invasive procedure, performed entirely through a small incision in your buttocks. The surgeon uses a guide pin to make a small hole in your ilium, the large bone that forms the top of your pelvis. The opening is drilled to allow access to the sacrum, which sits at the bottom of your spinal cord.

How the surgery progresses depends on each individual’s situation: bone grafts require cleaning out bone and cartilage before the graft is performed, while implants require screws and pins. The surgical site is irrigated or flushed, and the incision is closed with sutures. Surgery typically takes about an hour and, barring complications, you’ll go home the same day.

Postoperative Care

Full recovery takes around six months in order to allow the bone to fuse completely, but you can expect to see some symptom alleviation within a few weeks, sometimes immediately. 

If you exhibit the following signs upon returning home, contact your doctor:

  • Tenderness or swelling
  • Excessive drainage (changing the dressing every 4 hours)
  • Chills
  • A fever higher than 100.4 F
