Objective: We aim to evaluate the role of Ultrasonography (US) as a diagnostic tool for Cubital Tunnel Syndrome (CuTS) in comparison with the Nerve Conduction Study (NCS). Methods: Twenty elbows with CuTS and twenty asymptomatic controls were assessed by NCS and underwent ultrasonography of elbows. Patient and control data were compared to determine the diagnostic relationship in patients with CuTS and the degree of severity. Results: The NCS of the ulnar nerve, clinical parameters, and variable US measurements had a high degree of correlation. The CSA of the ulnar nerve was the most sensitive and 100% sensitive, 80% specific, and cut-off point of 9.5 mm2 behind the Medial Epicondyle. The diagnostic accuracy of the ulnar nerve ratio (UNR) was 95% sensitive and 85% specific. Conclusion: Ultrasonographic measurements of the ulnar nerve CSA and UNR are equivalent to noninvasive diagnostic measurements, which are an alternative method of CuTS assessment.
