Claim Text:
1. An intervertebral fusion cage comprising: a distal wall and a proximal wall spaced from the distal wall in a proximal direction; first and second side walls connecting the proximal and distal walls; an upper bearing surface adapted for gripping an upper vertebral endplate, and a lower bearing surface adapted for gripping a lower vertebral endplate, the upper bearing surface defining at least one upper opening therethrough adapted to promote bony fusion, and the lower bearing surface defining at least one lower opening therethrough adapted to promote bony fusion, the upper and lower openings together forming a throughhole, wherein the intervertebral fusion cage defines a first guide surface canal that 1) extends into the at least one of the upper and lower bearing surfaces, 2) extends through the distal wall so as to define a distal opening in the distal wall, and 3) defines a first guide surface, and wherein the intervertebral fusion cage is configured to receive a head of a bone screw through the distal opening in the proximal direction, such that the head is translatably received in the first guide surface canal and is guided within the first guide surface canal in the proximal direction toward the proximal wall.
