A method of trialing an intervertebral disc space, including the steps of creating the disc space, inserting a trial into the disc space, wherein the trial has i) a distal head having an upper surface and a lower surface connected by a pair of side walls, the side walls defining planes, and ii) a proximal rod, so that the head and rod form an obtuse angle and the rod extends through at least one of the planes defined by the side walls of the head.
