The Morphology of the Spinal Cord after Traction Injuries

Actuality .  Traction spinal cord injuries in children are of particular interest to researchers at present. Tractional damage associated not only with the trauma (SCIWORA syndrome), but can occur during elimination of deformation of the spine. The purpose of the study  was to study the peculiarities of morphological disorders of the spinal cord in traction mechanism of injury.  Materials and methods.  Performed 3 series of experiments on test machine AL-7 LA10. Dosed stretching of the spine of experimental animals (n=12) varied at 5, 10 and 20% of its original length. After 72 hours animals were removed from the experiment and carried out a histological study of the spinal cord. Results and their discussion.  It was found that after traction cyto - and myeloarchitectonic the cord was changed depending on the degree of stretching of the spine. If a strong tension (20%) of the neurons was exposed to irreversible changes. The recovery of the functional modules was probably due to the reorganization of surviving neural networks. Сonclusion .  The obtained data can be taken into account when planning the operations to eliminate kyfo-scoliosis spinal deformities in children.
