1. An intervertebral assembly, comprising:
an upper pivotable member configured to be disposed at least partially above an uppermost surface of a fusion device, the upper pivotable member having a distal end,
a lower pivotable member configured to be disposed at least partially below a lowermost surface of the fusion device, the lower pivotable member having a distal end, wherein the lower pivotable member is pivotable with respect to the upper pivotable member about a lower pivot location that is offset from the distal end of the lower pivotable member in a proximal direction, and the upper pivotable member is pivotable with respect to the lower pivotable member about an upper pivot location that is offset from the distal end of the upper pivotable member in the proximal direction, wherein the upper and lower pivot locations are offset from each other along a vertical direction that separates the upper pivotable member from the lower pivotable member;
wherein the intervertebral assembly is movable between a closed arrangement whereby the distal ends of the upper and lower pivotable members are spaced apart a first distance along the vertical direction, and an open arrangement whereby the distal ends of the upper and lower pivotable members are spaced apart a second distance greater than the first distance along the vertical direction.
