Sacroiliac Joint Anatomy

Shannon L Roberts. Phys Med Rehabil Clin N Am. 2021 Nov.

Abstract

The sacroiliac joint can be a source of low back pain. This review article summarizes current anatomic evidence of the innervation of the intraarticular and extraarticular parts of the sacroiliac joint relative to bony landmarks identifiable with fluoroscopy and ultrasound. This article aims to provide clinicians with an anatomic basis for clinical application to diagnostic blocks and radiofrequency ablation for sacroiliac pain to optimize clinical outcomes.

Keywords: Anatomy; Blocks; Innervation; Landmarks; Radiofrequency ablation; Sacroiliac joint.
