The ulnar nerve has to bear a large amount of compression, especially in the cubital tunnel, which can be deducted from the topographic relation of this nerve to the elbow. Apart from tightness of the tunnel, intraarticular changes can also cause compression of the nerve. A further narrow tunnel in the course of the ulnar nerve is the "loge de GUYON", situated in the hypothenar region. A careful neurological examination of sensory and motor signs as well as an accurate electromyographical examination differentiate compression syndromes from other neuropathies. Two unusual cases of a functional cubital tunnel syndrome are demonstrated: their cause was primarily a chondromatosis of the elbow joint in one case a functional vasal compression in the other case.
尺神经不得不承受大量的压迫，尤其是在肘管处，这可从该神经与肘部的解剖关系推断出来。除了管腔狭窄外，关节内的变化也可导致神经受压。尺神经走行过程中的另一个狭窄通道是位于小鱼际区域的“Guyon管”。仔细的感觉和运动体征神经学检查以及精确的肌电图检查可将压迫综合征与其他神经病变区分开来。本文展示了两例不寻常的功能性肘管综合征病例：一例主要病因是肘关节滑膜软骨瘤病，另一例是功能性血管压迫。
