Patent ID: 8591589

Claim:
A spinal stabilization system, comprising: a spacer sized for positioning within a disc space between adjacent first and second vertebrae, the spacer having: a convex front surface; a substantially planar rear surface positioned opposite the front surface; a top surface extending between the front and rear surfaces; a bottom surface opposite the top surface, the bottom surface extending between the front and rear surfaces; a first concave externally-facing side surface extending between the front and rear surfaces and extending between the top and bottom surfaces; and a second concave externally-facing side surface opposite the first side surface, the second side surface extending between the front and rear surfaces and extending between the top and bottom surfaces; wherein the first and second concave side surfaces extend at an oblique angle with respect to one another; and wherein the spacer has a height between the top surface and the bottom surface that is greater than a maximum width between the first side surface and the second side surface; and a fixation implant configured to connect the first and second vertebrae, the fixation implant being sized and shaped for positioning outside of the disc space and spaced from the spacer.
