Despite the fact that this connection is described by anatomists in XVIII century, its importance has only recently been appreciated because of the widespread of the electrophysiological techniques in clinical practies. However, in the Russian literature aspects of its practical value described so far is not enough. This article deals with the prevalence of the anastomosis, its anatomical and electrophysiological classification, options innervation of muscles of the hand, is carried out through him, described electrophysiological methods and criteria for its diagnosis, including the collision technique, in healthy subjects and patients with lesions of the median and ulnar nerves, given its practical value. Such a course of nerve fibers through this anastomosis can have a significant impact on the clinical manifestations in patients with lesions of the median and ulnar nerves, as well as the results of an electrophysiological study. Martin–Gruber anastomosis provides variability innervation muscles of the hand, which can make it difficult topic diagnostic damage to the median and ulnar nerves, in addition, because of the connection between the nerves of the clinical presentation may not reflect the extent of their defeat: the hand muscles function can be preserved with full nerve damage or, conversely, significantly disrupted with minimal nerve lesions. Moreover, different electrophysiological findings on patients with pathology of the median or ulnar nerves in the conditions of functioning anastomosis may also complicate the interpretation of the clinical data. Thus, knowledge of the anatomy and physiology of the Martin–Gruber communication as necessary for the electrophysiologist for correct interpretation of the finding and the clinician to accurately diagnose the pathology of the median and ulnar nerves and correct choice of treatment. </em></span></p></div></div></div></div
