Middle cluneal nerve entrapment neuropathy (MCN-EN) is a known cause of low back pain (LBP). Here, we succeeded in treating a patient with a lumbar disc herniation who actually had MCN-EN with a nerve block and neurolysis.
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.
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.
臀中皮神经卡压性神经病变（MCN-EN）是已知的下腰痛（LBP）病因。在此，我们成功治疗了一名腰椎间盘突出症患者，该患者实际患有MCN-EN，采用了神经阻滞和神经松解术。
一名52岁女性因严重的左下腹和大腿外侧疼痛而行走困难。腰椎MRI显示L5/S1水平左侧椎间盘突出。触诊时，我们在臀中皮神经穿过后上棘和后下棘之间的骶髂后长韧带处的臀部发现了一个触发点。在局部麻醉下进行了两次左侧MCN阻滞，随后进行了左侧MCN神经松解术。在术后10个月的最后一次随访中，下腰痛未复发，且她无需服用止痛药物。
在此，一名患有左侧L5S1椎间盘突出症和腰腿痛的患者通过神经阻滞继以神经松解术成功治疗了MCN-EN。
