FIELD: medical engineering. SUBSTANCE: device has overlay plate manufactured from flexible biologically inert high-strength material having at least two pairs of through holes in length and screws set into them with their heads anchorable for making attachment to the vertebrae. Central axes of the adjacent pairs of through holes are directed at an acute angle to the plane passing in perpendicular to the longitudinal plane of the overlay plate along its longitudinal axis from screw heads side for separating screw pair rods in each vertebral body. EFFECT: high strength of connection; small-sized incision. 10 cl, 8 dwg
