Study of the gunshot injuries features of peripheral nerves by modern weapons in the experiment

Abstract

The article shows the study results of the sciatic nerve pathomorphosis characteristics in gunshot wounds in experimental animals (pigs). Changes in the structure of nerve sheaths, its fascicles, features of nerve blood vessel injury were studied under optical magnification with digital recording of nerve histological sections. The ultrastructural changes of the sciatic nerve during the simulation of a gunshot wound of the peripheral nerve both with its anatomical section and with the preservation of anatomical integrity were studied. Histological examination of the sciatic nerve damaged by bullets of the 5.45 calibre showed significant morphological changes in the nerve structure both in case of anatomical section of the nerve and in case of its contusion. It has been proven that even if the anatomical integrity of the nerve is preserved, pronounced changes in the nervous tissue occur with a gunshot wound.
