An inter-vertebral cage with a wedge shape eccentrically located on the leading end of the cage. The ectopically shaped leading edge of this embodiment facilitates easier interbody spacer placement with less risk of nerve injury, as well as with likely decreased risk of destruction of the end plate during the distraction process when the interbody cage is impacted.
