Claim Text:
1. An intervertebral implant comprising: a body having an upper surface defining an upper plane and a lower surface defining a lower plane; a plate associated with the body, the plate having an upper surface lying substantially in the upper plane and a lower surface lying substantially in the lower plane, the plate having a first surface extending substantially perpendicular to the upper and lower planes and facing the body, the plate having a second surface extending substantially perpendicular to the upper and lower planes and facing in a direction opposite to that of the first surface away from the body, the plate including a first fastener hole, a second fastener hole, and a third fastener hole; a first fastener having a head and a shank, the first fastener hole being configured to retain the head of the first fastener between the upper and lower planes, a portion of the shank of the first fastener extending from the first fastener hole beyond the upper plane, the shank portion of the first fastener extending from the first fastener hole and being curved in a direction away from the upper surface of the body; a second fastener having a head and a shank, the second fastener hole being configured to retain the head of the second fastener between the upper and lower planes, a portion of the shank of the second fastener extending from the second fastener hole beyond the upper plane, the shank portion of the second fastener extending from the second fastener hole and being curved in a direction away from the upper surface of the body; and a third fastener having a head and a shank, the third fastener hole being between the first and second fasteners, the third fastener being configured to retain the head of the third fastener between the upper and lower planes, a portion of the shank of the third fastener extending from the third fastener hole beyond the lower plane, the shank portion extending from the third fastener hole and being curved in a direction away from the lower surface of the body; wherein the shank of each of the first, second, and third fasteners has a substantially circular cross section adjacent the head portion and a substantially flattened or peaked free end opposite the head portion, the shank portion transitioning from the circular cross section to the free end in a substantially continuous manner; wherein at least one spline of each of the first, second, and third fasteners is arranged on the shank of each of the first, second, and third fasteners, the spline extended from the circular cross section to the free end of the shank; wherein the at least one spline of each of the first, second, and third fasteners is arranged helically on the shank portion.
