초록

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.
