As with all nerve disorders, individuals with diabetes mellitus (diabetes type 2) have increased susceptibility for symptoms of ulnar nerve neuropathy, although these symptoms may occur secondary to a microvascular injury of the nerve, thus causing a local ischemia, or by interfering with local metabolism. Although there have been only a small number of studies examining occupational contributions to cubital tunnel syndrome, its prevalence ranges from 5.9 to 6.9% in workers in the Saint Louis metropolitan area (An, Evanoff, Boyer, & Osei, 2017), Missouri, USA (5.9%), a 6.9% prevalence rate in dock workers in Sao Paulo, Brazil (Saito et al., 2018), and 6.7% in floor cleaners in a systematic review performed in 2009 (van Rijn, Huisstede, Koes, & Burdorf, 2009). It is also reported to be more common in patients whose work involves protracted elbow flexion (e.g., holding a telephone) and flexion of the elbow on hard surfaces, workers who handle vibratory tools, and individuals with past elbow fractures, direct trauma of the ulnar nerve, or marked valgus or varus deformities of the elbow (Cutts, 2007; Saito et al., 2018).
