Sacro-Iliac (SI) Joint Fusion

The SI joint has received significantly more attention as a possible pain generator in recent years. It is a possible source of low back pain in patients with prior lumbar fusions but can also be a source of pain in patients without prior surgeries.

Diagnostic injections are often helpful in identifying this area as a pain generator and can be completed in our outpatient surgery center. Should criteria be met for SI joint dysfunction, then it is possible your provider may recommend an SI joint fusion as a possible therapeutic intervention. Please enquire further with your provider regarding this common source of low back pain.
