Sacroiliac joint injections and radiofrequency ablation for pain management: A clinical review

Figure 6 This medical illustration compares the sacroiliac joint pre and post radiofrequency ablation. A: This image shows the correct posterior anatomical view of the sacrum and ilium. The lateral branches of the posterior sacral nerves are visible, and a radiofrequency ablation probe is positioned on one of them, ready for the procedure; B: This image shows the same posterior view after the radiofrequency ablation procedure has been performed. A thermal lesion is now visible at the tip of the probe, and the targeted nerve is ablated, interrupting the pain signals. RFA: Radiofrequency ablation.
