Abstract:
1. An intervertebral spacer system, comprising: a first baseplate having an outwardly facing surface, an inwardly facing surface and an angled perimeter surface formed between the outwardly facing surface and the inwardly facing surface; a second baseplate having an outwardly facing surface, an inwardly facing surface, a pocket formed in the inwardly facing surface and an angled perimeter surface formed between the outwardly facing surface and the inwardly facing surface, the angled perimeter surface of the second baseplate corresponding to the angled perimeter surface of the first baseplate; and an intermediary member connected to the inwardly facing surface of the first baseplate and having an articulating portion adapted to engage the pocket of the inwardly facing surface of the second baseplate to provide relative articulation between the first and second baseplates, wherein the angled perimeter surface of the first and second baseplates include at least three flat surfaces forming two protruding corners, a first of the flat surfaces of each of the first and second baseplates converging with a second of the flat surfaces of each of the first and second baseplates to form a first of the protruding corners of each of the first and second baseplates, the first of the flat surfaces of each of the first and second baseplates also converging with a third of the flat surfaces of each of the first and second baseplates to form a second of the protruding corners of each of the first and second baseplates, wherein the first and second baseplates include a recess associated with each of the three flat surfaces or one of the protruding corners of the first and second baseplates, wherein the recess associated with each of the three flat surfaces or one of the protruding corners of the first and second baseplates forms an opposing recess pair with a recess associated with each of the three flat surfaces of the other of the first and second baseplates, and wherein each recess of the first and second baseplates has walls that define an access volume to accommodate a tool therein, the tool comprising a central flat surface adapted to lie adjacent, in a parallel fashion, to at least one of the flat perimeter surfaces of the first and second baseplates and a distal end having an extension member projecting therefrom for inserting into the access volume.
