[The formation of a distraction regenerate in the experimental modelling of the shape of the spinal canal].

The process of distractive regenerates of the vertebral arch was studied histologically in mature outbred dogs in modelling of vertebral canal by G. A. Ilizarov technique. During the process of distraction regenerate was shown to have a zonal structure i.e. to include 2 bone regions and connective tissue layering. Its growth is based on the fibers of that layering. The possibility of the increase of vertebral canal sagittal diameter up to 90-100% within 2-2,5 months due to the formation of vertebral arch distractive regenerates is supported by the results of present study and opens the perspective of this technique use in clinical practice.
