The pathogenesis of ulnar nerve subluxation and dislocation is widely debated. Upon elbow flexion, the ulnar nerve slips out of the groove for the ulnar nerve, relocates medial or anterior to the medial epicondyle, and returns to its correct anatomical position upon extension. This chronic condition can cause neuritis or neuropathy; however, it has also been suggested that it protects against neuropathy by reducing tension along the nerve. This article reviews the extant literature with the aim of bringing knowledge of the topic into perspective and standardizing terminology.

尺神经半脱位和脱位：文献综述。

尺神经半脱位和脱位的发病机制已引起广泛争议。肘部屈曲后，尺神经从尺神经的凹槽中滑出，重新定位到上epi内侧或内侧，并在伸展时返回其正确的解剖位置。这种慢性病会引起神经炎或神经病。然而，也有人建议通过减少神经张力来预防神经病变。本文对现有文献进行了综述，目的是将有关该主题的知识纳入观点并标准化术语。
