Abstract:
1. A trial implant system configured to be implanted in an intervertebral space along an insertion direction so as to determine the dimensions of an articulating total disc replacement implant or static interbody spacer, the trial implant system comprising: a trial implant configured to be inserted into an intervertebral space defined by a superior vertebral body and an inferior vertebral body, the trial implant defining a maximum length along the insertion direction and including: an inserter instrument including a first handle portion and a second handle portion that is movable relative to the first handle portion, the second handle portion defining an elongate portion, elongate along a central axis, that is integrally connected to a coupling portion, the second handle portion defining two locking elements at the coupling portion disposed on opposite sides of a plane that includes the central axis, the first and second handle portions each having a length along the insertion direction that is greater than the maximum length of the trial implant so as to define handle grips, wherein the first handle portion is configured to attach to the inferior plate, the second handle portion is translatable between a first axial position whereby the locking elements of the second handle portion are attached to the superior plate and a second axial position whereby the locking elements of the second handle portion are detached from the superior plate, and the superior plate is movable relative to the inferior plate when the locking elements of the second handle portion are in the second axial position and the first handle portion is attached to the inferior plate.
