Previously reported treatment strategies for this pain include conservative management, SI joint injection, radiofrequency denervation ablation, and SI joint fusion. Here, we describe the use of biportal endoscopic radiofrequency ablation (BERA) to treat patients with low back pain. From April 2018 to June 2020 he included her 16 patients who underwent ABR. The S1, S2, S3 foramen and her SIJ line were marked under fluoroscopy. The skin entry point was placed 0.5 cm medial to the SIJ line, at the level of the S1 and S2 foramen. Under local anesthesia, her 30° arthroscope with a diameter of 4 mm was inserted through the viewing portal. Surgical instruments were introduced through a separate caudal working portal. We resected the lateral branch of the S1-S3 foramen and the dorsal branch L5, which is the cause of SI arthralgia. At 1, 6 and 12 months post-surgery follow- up, clinically relevant improvements were noted in both the Visual Analogue Scale and the Oswestry Disability Index score. The patient's overall satisfaction rate was 89.1% for him. BERA for ISG pain treatment has the advantage that the innervating nerves to the joint are identified and removed directly. This technology allows for a wider working angle compared to traditional single-port endoscopes. Our study showed promising preliminary results.
