Intervertebral implant

A spine stabilizing system for stabilizing first and second vertebrae in a spinal column comprising:

• a plurality of bone screws having a threaded shaft and a head, the shaft having a longitudinal central axis;
• a three dimensional body formed of plastic configured for insertion between endplates of the first and second vertebrae, the three dimensional body having an upper surface for abutting the endplate of a first vertebrae, a lower surface for abutting the endplate of a second vertebrae, and a front surface;
• and
• a front plate formed of a metallic material having a top surface, a bottom surface, a superior surface and an inferior surface, the plate couplable to the three dimensional body such that the bottom surface overlies the front surface, the plate having a plurality of screw holes for receiving therethrough the shaft of the screws, the screw holes having a central axis, at least two of the plurality of screw holes extending through the front plate so that the axis of the screw hole is at an angle in the range of about 30° to about 70° relative to the bottom surface of the plate,
• wherein a first angled screw hole is angled in the front plate toward the superior surface of the front plate and the second angled screw hole is angled in the front plate toward the inferior surface of the front plate.

• a plurality of bone screws having a threaded shaft and a head, the shaft having a longitudinal central axis;
• a three dimensional body formed of plastic configured for insertion between endplates of the first and second vertebrae, the three dimensional body having a convex upper surface for abutting the endplate of a first vertebrae, a convex lower surface for abutting the endplate of a second vertebrae, a front surface, a back surface, a right side surface and a left side surface, the three dimensional body having a horizontal middle plane between the upper and lower surface and a vertical middle plane extending from the front surface to the back surface;
• and
• a front plate formed of a metallic material having a top surface, a bottom surface, a superior surface and an inferior surface, the plate couplable to the three dimensional body such that the bottom surface overlies the front surface, the plate having a plurality of screw holes for receiving therethrough the shaft of the screws, the screw holes having a central axis, at least two of the plurality of screw holes extending through the front plate so that the axis of the screw hole is at an angle in the range of about 20° to about 60° relative to the horizontal middle plane of the body,
• wherein a first angled screw hole is angled in the front plate toward the superior surface of the front plate and the second angled screw hole is angled in the front plate toward the inferior surface of the front plate and wherein the height of the front plate between the superior and inferior surfaces is substantially equal to or less than the maximum height between the upper and lower surfaces of the three-dimensional body.
