Cubital tunnel compression neuropathy in the presence of an anomalous venous complex: a case study
Abstract
https://doi.org/10.1016/j.xrrt.2023.04.001 2666-6391/Published by Elsevier Inc. on creativecommons.org/licenses/by-nc-nd/4.0 Compression or tension on the ulnar nerve about the elbowmay cause neuropathy known as cubital tunnel syndrome (CuTS). It is the second most common upper extremity neuropathy with an incidence of 24.7 cases per 100,000 persons per year.18,26,28,31 Common sites of compression include Osborne’s ligament, the 2 heads of the flexor carpi ulnaris (FCU), and the arcade of Struthers.20,26 Aside from these muscular and ligamentous structures, the ulnar nerve encounters several vascular structures including the superior ulnar collateral and posterior ulnar recurrent arteries.3,32 Along with these arterial structures, there have been scarce reports of ulnar nerve compression by anomalous venous structures.1,5 This study describes 2 cases of a cubital tunnel venous anomaly that may be a site of ulnar nerve compression not yet reported in literature. Although it is difficult to conclude the primary source of compression, these cases highlight the potential utility of diagnostic ultrasound (US) for the preoperative evaluation of such vascular anomalies. Both patients were informed and consented for the inclusion and publication of this case report.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
