Abstract:
1. A spinal spacer for engagement between vertebrae, comprising: a body having a first end surface at a distal end of the body and a second end surface opposite thereto at a proximal end of the body; the body extending between the first and second end surfaces to define opposing top and bottom vertebral engaging surfaces substantially symmetrical about a centerline axis, the body further defining side surfaces; a hollow inner body defined by an opening extending through the top and bottom vertebral engaging surfaces; the second end surface of the body including at least one aperture formed therethrough at an angle relative to the centerline axis and in communication with the hollow inner body; a bone screw having a threaded screw shaft configured and dimensioned to engage bone and a threaded screw head operably coupled to a proximal end of the screw shaft such that the threaded screw shaft is movable relative to the threaded screw head about at least one axis; and at least one insert having a screw opening defined therethrough and configured to be mounted to the body with the screw opening substantially aligned with the at least one aperture, the screw opening having a non-threaded lip formed therein, the non-threaded lip configured and dimensioned to engage the threads of the threaded screw head of the bone screw inserted through the at least one aperture.
