The cubital tunnel is the most common site of ulnar nerve entrapment. Previous ultrasound studies have demonstrated enlargement of the ulnar nerve in cubital tunnel syndrome but did not report on the cubital tunnel itself. Twenty-two individuals with cubital tunnel syndrome were evaluated with nerve conduction studies and ultrasound. The ultrasound measurement that most strongly correlated with conduction velocity was the ratio of ulnar nerve to cubital tunnel cross-sectional area with the elbow flexed. Measurement of this ratio may improve the diagnostic accuracy of ultrasound in cubital tunnel syndrome, although further investigation is needed.
肘管是尺神经卡压最常见的部位。以往的超声研究已证实肘管综合征中尺神经增粗,但未对肘管本身进行报道。对22例肘管综合征患者进行了神经传导研究和超声检查。与传导速度相关性最强的超声测量指标是屈肘时尺神经与肘管横截面积之比。尽管还需要进一步研究,但测量该比值可能会提高超声对肘管综合征的诊断准确性。
