Image-Guided Sacroiliac Joint Injections: an Evidence-based Review of Best Practices and Clinical Outcomes.

Abstract

Injections into the intraarticular sacroiliac joint (SIJ) are commonly done for both diagnostic and therapeutic reasons. Injection of an anesthetic can aid in the diagnosis of SIJ pain. Corticosteroids can be administered with the goal of providing a therapeutic effect. This article summarizes the literature regarding the diagnostic and therapeutic effects of these injections. It includes a review of the various imaging modalities including fluoroscopy, ultrasound, and computed tomography guidance, as well as a discussion on the prevalence data and other variables that may affect the reported outcomes.
