FIELD: medical engineering. SUBSTANCE: device has is designed as plates of given length provided with holes to match physiological curvature of anterolateral vertebral body segments. The holes have threaded conic and cylindrical portions. Fixing screws are designed as threaded rods with conic heads connected with threaded necks having additional thread which pitch is not less than 2.5 times as small than that of the threaded rods. Thread pitch of screw neck is equal to 2/3 of rod thread pitch. EFFECT: reliability in fixing vertebrae. 5 dwg
