目的：探讨上级臀神经（SCN）切断术治疗顽固性下腰痛（LBP）的临床和病理特点，以确定坐骨神经受压是否是导致这种类型LBP的机制。他们的临床结果和7神经的病理特征进行了review.ResultsAll患者报告LBP缓解后立即SCN神经切除术。7条切除神经的病理学研究显示明显肿大、有髓纤维密度降低、薄髓纤维增加（n= 2）、神经束膜增厚（n= 5）、神经束膜下水肿（n= 4）和雷诺体（n= 4）。在1条扩大神经的远端，我们观察到密度中度降低，大型有髓纤维数量显著减少。讨论神经切除术的病理结果和有效性表明，在我们的患者中，SCN神经病变可能通过神经压迫引起LBP。肌肉神经57：777-783，2018
IntroductionWe studied the clinical and nerve pathologic features in 6 patients whose low back pain (LBP) was relieved by superior cluneal nerve (SCN) neurectomy to determine whether nerve compression was the mechanism underlying this type of LBP.MethodsAll 6 patients (7 nerves) underwent SCN neurectomy for intractable LBP. Their clinical outcomes and the pathologic features of 7 nerves were reviewed.ResultsAll patients reported LBP relief immediately after SCN neurectomy. Pathologic study of the 7 resected nerves showed marked enlargement, decreased myelinated fiber density, an increase in thinly myelinated fibers (n= 2), perineurial thickening (n= 5), subperineurial edema (n= 4), and Renaut bodies (n= 4). At the distal end of 1 enlarged nerve, we observed a moderate reduction in the density and marked reduction in the number of large myelinated fibers.DiscussionThe pathologic findings and effectiveness of neurectomy suggest that, in our patients, SCN neuropathy likely elicited LBP via nerve compression.Muscle Nerve57: 777–783, 2018
