The sacroiliac (SI) joints are the foundation of the spine, located at the junctions of the sacrum and ilium on each side.

These complex joints, composed of systems of ligaments and multiplanar joint surfaces, transmit the forces exerted through the spine from the upper body to the legs. The SI joint is designed to absorb shock forces and is naturally limited to only minute motion. Instability in the SI joint is a major pain generator in some patients.

Although there have been many advances in surgical techniques to address instability problems in the lumbar spine, instability in the SI joint has remained unaddressed, with most patients running out of options once conservative treatments have failed to offer continued relief from painful SI symptoms.

Causes of SI Joint Instability and Pain

• Prior injury or accident
• Arthritis
• Low back instability or prior low back surgery
• Ligamentous loosening due to pregnancy

When it is suspected that some or all of the patient’s symptoms could be attributed to SI joint instability, it is recommended to begin with conservative treatment options. Conservative treatment may include physical therapy, chiropractic manipulation, patient-specific exercise programs, or bracing.

Pain management evaluation and intervention may be the next step, including pain medications or therapeutic injections that may provide some patients temporary relief but often only work short term. Radiofrequency ablation (RFA) has also been used with some success, but similar to injections, it may only provide temporary relief.

SI joint stabilization should only be considered after non-surgical interventions have failed to provide a patient with an enduring solution to their pain. Stabilizing the SI joint can provide enduring pain relief.
