Entrapment neuropathies(EN), which are focal forms, are so frequent at any stage of the diabetic disease, that they may be considered a neurophysiological hallmarkof peripheral nerve involvement in DM. Indeed, EN may be the earliest neurophysiological abnormalities in DM,particularly in the upper limbs, even in the absence of a generalized polyneuropathy, or it may be superimposed on a generalized diabetic neuropathy. This remarkable frequency of EN in diabetes is underlain by a peculiar pathophysiological background. Due to the metabolic alterations consequent to abnormal glucose metabolism,the peripheral nerves show both functional impairment and structural changes, even in the preclinical stage,making them more prone to entrapment in anatomically constrained channels. This review discusses the most common and relevant EN encountered in diabetic patient in their epidemiological, pathophysiological and diagnostic features.展开更多
