[The mechanisms of the injuries to the nerve trunks in gunshot wounds of the extremities (experimental research)].

Two series of experimental researches were conducted on rabbits who had received gunshot wounds of the hind pads inflicted by middle and high velocity missiles. On the basis of the data obtained with the help of electroneuromyography, as well as light and electronic microscopy, it was found out the correlation of clinical, electrophysiological and pathomorphological parameters. Morphofunctional changes were disclosed not only in the proper zone of wound, but also at the upper and lower sides of sciatic nerve, as well as in central nerve system (SNS). The results obtained during these researches give the possibility to make a conclusion that coexistent lesions of nerves in gunshot injuries depend on the velocity characteristics of a missile and have compressive-tractive mechanism. "Central disorders" which appear in SNS exert a strong influence on the development of degenerative-regenerative changes.
