Pain originating from the posterior sacroiliac complex is notoriously difficult to effectively treat due to its complex anatomy and variable innervation. Data on radiofrequency ablation (RFA) is limited. The Abbott Simplicity probe creates 3 monopolar lesions along the medial aspect of the sacroiliac joint and 2 bipolar lesions between the active portions of the probe. This device has been studied previously with improvement of pain-associated disability and pain reduction, but insufficient data is present to determine its utility at this time. Using the most recent literature for the potential innervation of the posterior sacroiliac joint, it is reasonable to explore this novel device and its ability to treat sacroiliac joint pain.
