Cubital tunnel compression neuropathy in the presence of an anomalous venous complex: a case study

Compression or tension on the ulnar nerve about the elbow may 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.
