Abstract
A spinal spacer for engagement between vertebrae includes a body extending between a substantially contoured first end surface and a second end surface to define side surfaces and opposing top and bottom vertebral engaging surfaces substantially symmetrical about a centerline axis. At least one opening defines a hollow inner body and includes first and second intersecting openings extending through the top and bottom vertebral engaging surfaces. The second intersecting opening extends through the side surfaces. The second end surface includes at least one aperture formed therethrough in communication with the hollow inner body. A screw opening is defined through at least one plate insert configured to be removably coupled to the second end surface to substantially align the screw opening with the at least one aperture. The bone screw is configured to be threadingly secured within the at least one plate insert.
