摘要:
The invention relates to medicine, namely to traumatology, neurosurgery, orthopedics, prosthetics and provides vertebrology shattered bodies of the cervical, thoracic and lumbar vertebrae. Summary of the utility model is that the adjustment of the vertebral body prosthesis comprises a hollow cylindrical body, at one end of which is fixed to the lower base of a cylindrical cover, in which there are undulations latches constituting the floor holes with a constant pitch. On the cylindrical surface of the housing is provided with through slots. At the other end of the housing is formed an outer collar and on the inner cylindrical surface of the housing are arranged non-through longitudinal slots, which may be four. On the body side flange mounted nut and a threaded inner groove. In the inner groove on the nut installed spreader ring, preventing movement of the nut relative to the axial direction of the body. The hollow cylindrical telescopic column has an external thread corresponding to the threads on the nut so that they form a screw pair. A threaded connection may have a rectangular profile. At the end of the column is fixed in the upper base of a cylindrical cover having a wave-like clamps, which are poluotverstiya constant pitch. On the cylindrical surface of the column formed grooves, wherein the column portion can enter inside the hollow cylindrical body, on the inner cylindrical surface of the hollow body there are longitudinal grooves so that the longitudinal projections formed in the outer cylindrical surface of the hollow cylindrical column sliding can freely enter into the slots on the body. Means for fixing the height of the endoprosthesis is composed of two groups of openings arranged on the cylindrical surface of the hollow body, wherein in one group of holes located closer to the lower base - smooth (for fixing the tool, carrying the prosthesis distraction) and the other containing an internal thread, one of which screw locking shoulder screw which is a
