In acute and chronic experiments on 52 animals (rabbits and dogs), carried out by means of neurophysiologic and neurohistologic methods, the authors have studied functional and histologic changes in the nerves following a one-step forced traction. Traction injuries have been found to cause early trophic disorders, persistent and long-lasting alterations of the nerve conductability and excitability. Some considerable retrograde changes in the nerves and related segments of the spinal cord have been noted together with the delay of the resorption of the decay products of the axons and the myelin sheath in the peripheral nerve fragment. The severity degree of the alterations depends on the degree of the traction.
