Two three-dimensional geometric solid-state models of the Th7-L1 spinal segment (Model 1, Model 2) with metal construction were built. Models include the vertebrae Th7, Th8, Th9, Th10, Th11, Th12, L1, intervertebral discs, facet joints and ligaments, and metal construction elements. In Model 1, the cortical and spongy layers are constructed by three-dimensional solids, facet joints and intervertebral discs by three-dimensional bodies, ligaments by one-dimensional objects.

The Cortical Bone Tissue Controlled Recovering After Treatment in the External Fixation Apparatuses

Authors: Akulich Y. V., Akulich A. Y., Bryukhanov P. A., Denisov A. S.

The paper represents the new bone tissue rehabilitation method. The rehabilitation control loads are affected to the regenerative lower extremity by the use of a special training device. The adaptive changes of the elasticity modulus, porosity, volumetric mineral content and strengthening of the cortical bone tissue are simulated during the union of a bone using the external fixation apparatus (by example of the Ilizarov’s pin apparatus) and the following rehabilitation time.
