Sacroiliac Joint Pain

Sacroiliac joint pain, also known as SI joint pain, often presents as low back or hip pain. In fact, up to 30% of low back pain is caused by sacroiliac joint pain or sacroiliitis. The physicians at Centurion Spine & Pain Centers are experts at diagnosing and treating SI joint pain.

What Is

SI Joint Pain?

The SI joint connects the spine to the pelvis. Sacroiliac joint pain is usually felt in the lower back, buttock or hip region, and can spread down the back of the leg or into the groin. It is often worse with getting up out of a chair or walking.

Causes of

SI Joint Pain

Sacroiliac joint pain most commonly affects people who have had previous back surgery, joint replacement, or have leg length discrepancies. All of which can cause excess stress on the joint. Sacroiliac joint dysfunction can also be seen after or during pregnancy due to the stress on the pelvis.

Treatments for

SI Joint Pain

Centurion Spine & Pain Centers offers several treatment options for SI joint pain, including:

  1. Medication Management & Therapy
  2. Sacroiliac joint injections
  3. Nerve Blocks
  4. Radiofrequency Ablation
  5. Sacroiliac Joint Stabilization
  6. Sacroiliac joint fusion
  7. Neurostimulation


Sacroiliac Joint


Sacroiliac joint stabilization (also referred to as a posterior sacroiliac joint fusion) is a minimally invasive procedure involving one small incision that can be done in an outpatient surgery center. It is a quick procedure that can usually be done in less than 30 minutes and only requires light sedation. 

During a sacroiliac joint stabilization, a bone graft smaller than the size of an almond is placed in the center part of the sacroiliac joint through a small incision. The implant will help to initially stabilize the SI joint, and prevent it from causing irritation, inflammation and pain.

Patients go home the same day and have very few restrictions for two weeks. By 4-6 weeks, most patients will experience a significant reduction in their SI joint pain.
