The treatment modality for failed back surgery syndrome (FBSS) is currently being researched. We evaluated whether a posterior sacroiliac ligament block could successfully alleviate sacroiliac joint (SIJ) pain in 64 patients with FBSS. The sequential changes in the numerical rating scale (NRS) were evaluated in out-patients, following the administration of a posterior sacroiliac ligament block. The duration of symptoms of FBSS, the sites of pain, and the type of surgery required were analyzed. Out of 64 patients with FBSS, 55 patients were diagnosed with SIJ pain. In 47 of these 55 cases (85.5%), the pain was relieved using a posterior sacroiliac ligament block alone. The average duration of the FBSS was 18 months. It was noted that 68.1% of the patients complained of not only low back pain, but also leg pain. Greater than 50% improvement in the NRS from the first block was observed in 53.2% of patients. This study showed that a posterior sacroiliac ligament block may be effective in relieving FBSS pain, both as a diagnostic method and as treatment.
