Radiofrequency ablation, nerves innervating the sacroiliac joint, with image guidance (ie, fluoroscopy or computed tomography)

Radiofrequency ablation (RFA) of the nerves innervating the sacroiliac (SI) joint is a medical procedure designed to alleviate pain associated with dysfunction of the SI joint. The SI joints are located where the sacrum meets the hip bones on either side of the spine, playing a crucial role in weight-bearing and movement. This procedure targets the specific nerves that transmit pain signals from the SI joint, providing patients with longer-lasting relief from low back pain and/or sciatic pain. RFA is considered a minimally invasive technique, often performed under mild sedation to enhance patient comfort. Prior to the RFA, a lateral branch block may be performed to assess the effectiveness of the procedure by temporarily blocking pain signals from the affected nerves. The use of imaging guidance, such as fluoroscopy or computed tomography, ensures precise placement of the RFA needle, which is essential for the success of the procedure. Overall, RFA is a valuable option for patients suffering from chronic pain related to SI joint dysfunction, aiming to improve their quality of life through effective pain management.
