Patent ID: 8216316

Claim:
A prosthetic implant system comprising: a fusion cage comprising a cage body having a plurality of surfaces, said plurality of surfaces cooperating to define a multi-planar angulation adapted to achieve substantially flush fitment in a lordotic disk space between adjacent vertebrae when said fusion cage is inserted in said lordotic disk space; and an insertion tool for securing to said fusion cage to permit a user to insert and place said fusion cage into a disk area; said fusion cage comprising a plurality of apertures or slots, said plurality of apertures or slots being of different shapes or sizes; said insertion tool having a plurality of projections having a plurality of different shapes or sizes that complement the shapes or sizes of the plurality of apertures or slots, respectively, to prevent relative rotational movement between said insertion tool and said fusion cage; wherein said insertion tool further comprises indicia to facilitate proper placement of said fusion cage after said fusion cage is mounted on the insertion tool and before it is inserted between said adjacent vertebrae; said plurality of apertures or slots being asymmetrical for directional coupling of said fusion cage to said insertion tool.
