摘要：
The group of inventions relates to medicine and can be used in neurosurgery in the treatment of spinal disorders and injuries. The present vertebral body replacement is comprised of a central hollow rod with a thread which runs in opposite directions from the middle of the rod, onto which half bodies are screwed, said half-bodies being provided with teeth on their outside ends and L-shaped half-plates with paired screw holes. The half-bodies are provided with lateral radial through holes of equal diameter, which are arranged in tiers. Ports are provided in the hollow-bodies, below the L-shaped half-plates. Bridges between the ports and the outside faces of the half-bodies are flat and have a minimum possible thickness in their central regions. Once a vertebral body replacement has been positioned between adjacent vertebrae, the sagittal profile of the operated vertebral segment is overcorrected and the requisite additional amount of filler is added to the cavity thus formed in the vertebral body replacement until said cavity is completely filled, whereupon the filler is compacted. The half-bodies of the vertebral body replacement are secured by forcibly bending the thin bridges into grooves in the rod. The group of inventions provides that the cavity of a vertebral body replacement is completely filled with filler, that a bone block is formed which provides adequate support, and that the half-bodies are secured firmly relative to the rod.Ce groupe dinventions se rapporte au domaine de la médecine et peut être utilisé en neurologie dans le traitement de troubles et de dommages de la colonne vertébrale.. Limplant pour vertèbre consiste en un montant creux central avec des filetages allant dans différentes directions de puis son centre, sur lesquels viennent se visser un demi-corps avec des dents à leurs extrémités externes, et comportant des demi-plaques en forme de Г avec des ouvertures appariées sous les vis. Les demi-corps comportent des ouvertures radiales latéral
