Three-dimensional plots of stress on cephalad graft surface for different iterations of the InterPlate design. (a) The InterPlate titanium device having dynamic surface features, (b) The InterPlate design without teeth representing a non-dynamic device. The plate shields the anterior portion of the graft, (c) The InterPlate design in titanium without teeth and having a fully enclosed graft chamber, (d) The InterPlate design in unfilled PEEK without teeth and having a fully enclosed graft chamber.
