摘要：
The invention relates to medicine, namely to traumatology, orthopedics, Spine, including ftiziovertebrologiyu. The invention provides a prosthetic bodies destroyed cervical, thoracic and lumbar vertebrae at their traumatic, inflammatory and neoplastic lesions.The utility model solves the problem of migration of the prosthesis, preventing the development of instability in the operated segment and eliminates the need for re-operation. This problem is the main telescopic prosthesis during implantation of the vertebral bodies at Zama vertebrae at their destruction, inflammation, tumors.Telescopic vertebral body prosthesis comprises an upper cylindrical base, at the end of which is formed an upper supporting platform, the bottom cylindrical base, at the end of which is formed lower supporting platform, an annular coupling means and the height of the prosthesis fixation. Upper cylindrical base with an external thread and annular internally threaded coupling form a helical pair and a lower cylindrical base with an annular groove and an annular sleeve with an annular shoulder formed rotationally movable connection with gearing. On the side and end surfaces of the prosthesis are made and the central slots, wherein the area of the slit and the central holes should be 50-60% of the total surface area of the prosthesis.On the outer perimeter of the upper and lower support platforms evenly as belt clips installed arrow shaped.Arrow-shaped retainer may have a leg and the tip of a rectangular or circular cross-section. Furthermore, the tip profile may be straight or concave edge.A threaded joint has a trapezoidal profile.the height of the prosthesis fixation means includes threaded openings in the side surface of the lower cylindrical base and comb semicircular recesses formed on the perimeter of the lower end surface of the annular sleeve and the locking screw.The side surface of the upper base formed of uniformly bred and alternating threaded section and a cylindrical sectio
