Claim:
1. A method of inserting a fusion cage into a disc space defined by upper and lower endplates, the cage comprising: i) a distal portion, an intermediate portion, and a proximal portion, ii) an anterior wall having a distal portion, an intermediate portion, a proximal portion, and a center hole, iii) first and second opposed side walls extending from the anterior wall, each sidewall having a distal portion, an intermediate portion, a proximal portion, and an opposed throughhole, the method comprising: a) inserting the fusion cage into the disc space in an orientation in which the anterior wall is substantially parallel to a selected endplate and the distal portion of the anterior wall is more anterior than the proximal portion of the anterior wall, b) moving the distal portion of the anterior wall so the distal portion of the anterior wall is further from the selected endplate than the proximal portion of the anterior wall and so that the anterior wall faces anteriorly.
