Instrumentation for implanting an artificial intervertebral disc includes
static trials, the static trials including first and second trial
baseplates immovably coupled to one another via a trunk extending
therebetween, each trial baseplate having an outwardly facing surface
approximating a contour of a corresponding outwardly facing surface of an
articifial intervertebral disc baseplate, at least one of the trial
baseplates having a plurality of engagement holes extending into the at
least one of the trial baseplates in a direction substantially
perpendicular to each of a plurality of a surgical approach directions
used to insert the trial into the intervertebral space, each of the
plurality of engagement holes being disposed on the at least one of the
trial baseplates to correspond to a respective one of the surgical
approach directions such that selection for use of one of the plurality
of engagement holes corresponds to selection of the respective surgical
approach.
