Sacroiliac (SI) joint injections deliver anti-inflammatory medication directly into the SI joint — the joint connecting the spine to the pelvis — to reduce pain and inflammation. SI joint dysfunction is a common cause of lower back and buttock pain following car accidents and workplace injuries.
Diagnostic and Therapeutic SI Joint Injections
Like facet joint injections, SI joint injections can be used diagnostically (to confirm the SI joint as the pain source) or therapeutically (to reduce inflammation and pain). Diagnostic injections use local anesthetic; therapeutic injections add corticosteroid. The procedure is performed under fluoroscopic guidance to ensure accurate needle placement within the joint.
Recovery and Next Steps
Most patients experience significant pain relief within a few days of the injection. Pain relief from corticosteroid injections typically lasts weeks to months. If diagnostic injections confirm the SI joint as the primary pain source but relief is temporary, radiofrequency ablation of the sacral lateral branch nerves may be recommended for more durable pain relief.
