Objective: To evaluate the relationship among the clinical characteristics, electrophysiological severity and sonographic findings of cubital tunnel syndrome (CuTS). Method: We enrolled 19 patients with CuTS and 19 healthy adults. We evaluated body mass index (BMI), symptom duration, self-administered questionnaire of the ulnar neuropathy at the elbow (SQUNE), McGowan score and electrophysiological severity score by Mondelli. We measured the crosssectional area of the ulnar nerve and cubital tunnel, and the ratio of the ulnar nerve to cubital tunnel. The long and short axis of the ulnar nerve were measured in diameters with the elbow flexed and extended. Results: The ulnar nerve, with the elbow flexed and extended, was larger in the CuTS group than in the healthy control group (p< 0.05). However, there is no significant difference between BMI and the cubital tunnel area. The electrophysiological severity score was correlated with the SQUNE (r=0.738, p=0.010) and McGowan score (r=0.810, p=0.002), but not with the symptom duration. Sonographic findings did not correlate with the symptom duration, SQUNE, McGowan score, and electrophysiological severity score. Conclusion: Sonography can detect the morphological changes in the ulnar nerve in patients with the CuTS. However, the best predictors of clinical characteristics in the CuTS seem to be the electrophysiological severity rather than the sonographic findings.
