Resumen

Radiofrequency ablation (RFA) is a potential treatment for those with sacroiliac joint (SIJ) pain. There is no consensus on the optimal procedural techniques for SIJ diagnostic blocks, or RFA. This article describes different techniques for SIJ diagnostic blocks and RFA, including the relevant innervation that underlies these techniques. SIJ RFA techniques differ in important ways, including lesioning techniques, needle placements, and type of RFA cannula used. Clinicians utilize a variety of image guidance modalities for SIJ RFA; fluoroscopic guidance is standard, although endoscopic and ultrasound-guided techniques are described. Additional studies are necessary to delineate potential differences between SIJ RFA techniques.
