Bilateral hypothenar muscular spasm ("dimpling") was discovered in a 62 year-old man. The spasms consisted of recurrent arrhythmic contractions of the palmaris brevis muscle. E.M.G. showed no signs of denervation but the contractions could be stopped by infiltration of the ulnar nerve by xylocaine. Apparently, this syndrome has previously been reported in only two cases. Its clinical and electromyographic characteristics are similar to hemifacial spasm. Compression of the ulnar nerve after its division at the wrist could be a cause.
在一名62岁男性中发现双侧小鱼际肌痉挛（“酒窝征”）。痉挛表现为掌短肌反复无节律性收缩。肌电图未显示失神经支配迹象，但利多卡因浸润尺神经可使收缩停止。显然，此前仅报道过两例该综合征。其临床和肌电图特征与面肌痉挛相似。尺神经在腕部分支后受压可能是一个病因。
