Abstract

We performed short segment incremental stimulation on 13 consecutive patients with ulnar neuropathy across the elbow (UNE) and conduction block. Conduction block occurred proximal to the medial epicondyle in 62%, at the epicondyle in 23%, and below the elbow in 15%. The ulnar nerve may be more prone to external compression above the elbow than previously recognized. Short segment incremental studies are useful to identify conduction block above the elbow in such patients.

摘要

我们对13例连续性尺神经肘管综合征（UNE）合并传导阻滞患者进行了短节段递增刺激。传导阻滞发生在内上髁近端的占62%，在内上髁处的占23%，在肘部以下的占15%。尺神经在肘部以上可能比之前认为的更容易受到外部压迫。短节段递增研究有助于识别此类患者肘部以上的传导阻滞。
