FIELD: medical engineering. ^ SUBSTANCE: device has two overlay members adapted to anterolateral surfaces of vertebral bodies. The overlay members have two or three conic central and through threaded holes, bone screws having conic heads, plate with two through end holes and fixing screws. The bone screws are introduced into the through holes in the overlay members. Rectangular slots are produced in the overlay members, one of them having a dead slot and the other one having through slot, both matching the end parts of the plates in size. One of through holes in the end part of plate is oval. Parallel teeth arranged in perpendicular to lateral walls are produced on the plate end part surface and on through slot surface of one of the overlay members. ^ EFFECT: enhanced effectiveness in fixing anchoring vertebral bodies with different diastasis value and retained correction angle. ^ 8 dwg |
