Distal Ulnar Neuropathy from Carpal Ganglia: A Clinical and Electrophysiological Study

Abstract The clinical and electrophysiological observations in two cases of distal ulnar neuropathy from carpal ganglia are reported. In the first case, the ganglion was compressing the ulnar nerve just proximal to its division; in the second case, the ganglion was compressing the deep branch of the ulnar nerve just at its origin. In both cases, both axonal degeneration and segmental demyelination were present. A clinical classification of the compression syndromes of the deep ulnar branch is proposed.

Significant Disability

IntroductionUlnar neuropathy with abnormal non-localising electrophysiology (NL-UN) is often associated with significant disability that is difficult to manage due to the absence of anatomically defining studies. We studied demographic, clinical and electrophysiological characteristics of NL-UN and used ultrasound in order to assist with classification and to examine the utility of ultrasound over and above the conventional electro-diagnostic approach.MethodNL-UNs were identified from 113 consecutive referrals to a single neurophysiologist with suspected ulnar neuropathy. All received systematic electro-diagnostic tests and ulnar nerve ultrasound. NL-UN severity was graded using clinical and electrophysiological scales.ResultsIn 64 of 113 referrals, an ulnar mononeuropathy was confirmed by electrophysiology. Sixteen of these 64 (25%) had NL-UN, predominantly males (14 out of 16 patients) with severe or moderately severe clinical and electrophysiological ratings in 81%. Ultrasound showed focal ulnar neuropathy at the elbow (UNE) in 13 out of 16, and diffuse ulnar nerve abnormality in three, and identified a likely or possible causative mechanism in 11 UNEs.ConclusionA quarter of ulnar neuropathies, as demonstrated by abnormal electrophysiology, were NL-UN, of heterogeneous aetiology; the majority were males with significant disability and axonal loss. Ultrasound had a significant role in localization and classification of NL-UN that facilitated management.

Abstract Background Various surgical options are used for the treatment of ulnar nerve entrapment at the elbow. In this study, anterior trans-muscular transposition of the ulnar nerve was used for the treatment of cubital tunnel syndrome. Objectives To evaluate the surgical results of anterior trans-muscular transposition technique for the treatment of cubital tunnel syndrome with particular emphasis on clinical outcome. Methods Forty patients with cubital tunnel syndrome were operated using anterior trans-muscular transposition technique. Patients were classified into post-operative clinical outcome grades according to the Wilson & Krout criteria, and they were followed up by visual analog scale (VAS), the Disability of Arm Shoulder and Hand (DASH) questionnaire, electrophysiological study, and post-operative clinical evaluation. Results Forty patients with cubital tunnel syndrome who underwent anterior trans-muscular transposition of the ulnar nerve show a significant clinical improvement at 24 months post-surgery regarding visual analog scale (VAS), the Disability of Arm Shoulder and Hand (DASH) questionnaire, electrophysiological study, and the Wilson & Krout grading as 87.5% of the patients recorded excellent and good outcome. Conclusion Anterior transmuscular transposition of the ulnar nerve is a safe and effective treatment for ulnar nerve entrapment at the elbow.
