Current Diagnostic Practices for Sacroiliac Joint Pain Among Interventional Pain Physicians: Results of an Exploratory Practice Survey

Background

Sacroiliac (SI) joint pain contributes to chronic axial low back pain, but diagnosis remains challenging because no single historical feature, physical examination maneuver, imaging finding, or injection response is universally accepted as definitive. Although guidelines recommend multimodal assessment, less is known about how interventional pain physicians diagnose SI joint pain in real-world practice.
