L-shaped body having a first end configured to be attached to a first
location of the interbody cage, a second end configured to be attached to
a first location of the first vertebra and a corner formed between the
first and second ends and configured to be attached to a second location
of the first vertebra or a third location of the interbody cage. The
second plate comprises a first end configured to be attached to a second
location of the interbody cage and a second end configured to be attached
to a first location of the second vertebra.
