Intra-Articular Sacroiliac Joint Injection: Technical Guide.

Sacroiliac (SI) joint pathology has been an increasingly discussed pathology as a potential etiology for significant low back and lower extremity pain. While patient history and examination maneuvers can assist with identifying the SI joint as a potential cause of pain, an intra-articular SI joint injection is critical to properly diagnose the SI joint as a clinically relevant pain generator. In addition to the diagnostic information from the injection, SI joint intra-articular injections can be performed for therapeutic benefit as part of a multi-modal, conservative treatment approach for SI joint pathology. We discuss our technique for safe and effective SI joint intra-articular injections as a both diagnostic and therapeutic aid for SI joint pathology.
