Abstract:
1. A system comprising: a two-piece intervertebral disc replacement device including, a first member having a first mounting hole and a first bone screw hole; and a second member having a second mounting hole and a second bone screw hole, and an insertion plate including, a base having a perimeter; a first mounting element of the base operable to engage the first mounting hole of the first member of the two-piece intervertebral disc replacement device; a second mounting element of the base operable to engage the second mounting hole of the second member of the two-piece intervertebral disc replacement device, wherein the perimeter does not extend over the first and second bone screw holes when the first and second mounting elements cooperate to engage and orient the first and second members of the two-piece intervertebral disc replacement device for simultaneous insertion into an intervertebral disc space of a spinal column; and a stem extending away from an anteriorly directed surface of the base and operable to facilitate movement of the intervertebral disc replacement device and insertion thereof into the intervertebral disc space such that the first and second members may be at least one of inserted into and moved within the intervertebral disc space without substantially changing their orientation with respect to one another, the stem being sized and shaped for engagement with an insertion handle to further facilitate movement of the intervertebral disc replacement device, wherein one of the stem and the insertion handle includes a bore and the other of the stem and the insertion handle includes a tapered shaft that frictionally engages the bore to facilitate detachable engagement with one another.
