Abstract

Introduction: We 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.Methods: All 6 patients (7 nerves) underwent SCN neurectomy for intractable LBP. Their clinical outcomes and the pathologic features of 7 nerves were reviewed.Results: All 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.Discussion: The pathologic findings and effectiveness of neurectomy suggest that, in our patients, SCN neuropathy likely elicited LBP via nerve compression.

Abstract

A 51-year-old man had a 1-year history of numbness on the ulnar side of the 4th finger, the 5th finger, and the ulnar side of the forearm, and weakness of the right hand. The Spurling sign was negative, and cervical radiography and magnetic resonance imaging revealed no abnormality. The Tinel-like signs at the Guyon's canal and cubital tunnel were positive. The diagnosis upon electrophysiological examination was cubital tunnel syndrome and Guyon's canal syndrome, but the possibility of Guyon's canal syndrome was high. Based on the presence of numbness in the forearm, the Tinel-like sign at the cubital tunnel, and the high incidence rate of cubital tunnel syndrome, an operation for cubital tunnel syndrome was performed. After the first operation, the numbness in the forearm was improved, but numbness in the 4th and 5th fingers, and weakness of the right hand remained, and the Tinel-like sign at the Guyon's canal also remained positive. The second operation for Guyon's canal syndrome was performed a month after the first operation for cubital tunnel syndrome. After the second operation, the residual symptoms improved gradually. Guyon's canal syndrome is a rare condition, but it may be considered a causative factor in patients with ulnar neuropathy.
