Here, we succeeded in treating a patient with a lumbar disc herniation who actually had MCN-EN with a nerve block and neurolysis. Case Description: A 52-year-old female presented with severe left lower back and lateral thigh pain making it difficult to walk. The lumbar MRI revealed a disc herniation on the left at the L5/S1 level. On palpation, we identified a trigger point on the buttock where the MCN penetrates the long posterior sacroiliac ligament between the posterior superior and inferior iliac spine. Two left-sided MCN blocks, followed by the left MCN neurolysis procedure, were performed under local anesthesia. At the last follow-up, 10 months after surgery, the LBP has not recurred, and she requires no medications for pain control. Conclusion: Here, a patient with a left-sided L5S1 disc herniation and low back/leg pain was successfully treated for MCN-EN with nerve block followed by neurolysis.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/b30d6484-e12c-48fa-bff4-e81e0ab1574b/featured/hero-1781562605968.png","publishDate":"2021-03-30T00:00:00.000Z","doi":"10.25259/SNI_167_2021","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2021/03/10677/SNI-12-132.pdf"}
