The state of the tibial nerve, intramuscular nervous fasciculi and terminals in muscles and skin has been studied in the canine extremities at large one-stage elongations after G. A. Ilizarov. By means of neuromorphological methods it has been proved that during the distraction in the tibial nerve microscopical areas of overstrain of the nervous fibers are formed. This results in appearance of degenerative alterations both in the nerve itself and in the tissues, which it innervates. Together with the destructive processes, during all stages of distraction in the extremity, regeneration of nervous apparatuses took place. However, reparative processes were poorly manifested during those stages. Only after distraction is stopped (in 6 months--period of the extremity fixation) the regenerative processes predominate. It is possible to suppose that the manifestation degree of degenerative and reparative changes depends immediately on duration of distraction.
在采用G. A. 伊里扎洛夫技术进行犬类肢体大幅度一期延长术后，对胫神经、肌内神经束以及肌肉和皮肤中的神经末梢状态进行了研究。通过神经形态学方法已证实，在胫骨神经牵张过程中会形成神经纤维过度拉伸的微观区域。这会导致神经本身及其所支配组织出现退行性改变。在肢体牵张的各个阶段，除了破坏过程外，神经装置也会发生再生。然而，在这些阶段修复过程表现不佳。只有在牵张停止后（在肢体固定的6个月期间），再生过程才占主导。可以推测，退行性和修复性变化的表现程度直接取决于牵张持续时间。
