摘要:
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.
