Intervertebral implant

An intervertebral implant for being implanted between adjacent vertebrae, the intervertebral implant comprising:

• a generally elongate implant body extending along a longitudinal axis between longitudinal ends, and having an intermediate portion located between the longitudinal ends;
• a pair of spaced side walls extending longitudinally along the longitudinal axis;
• a lateral wall of the intermediate portion extending transverse to the longitudinal axis;
• a superior face of the implant body;
• an inferior face of the implant body;
• the superior face and the inferior face being spaced such that the elongate implant body has a varying height as the elongate implant body extends along the longitudinal axis;
• one of the longitudinal ends being a tapered, nose end having a height less than that of the intermediate portion;
• the other longitudinal end being a tail end having a height less than that of the intermediate portion and having a tool attachment portion formed therein;
• an interior surface of the implant body including an interior surface portion on one side of the lateral wall and an interior surface portion of the tapered, nose end that are spaced from and face each other, and first interior surface portions of the side walls that are spaced from and face each other and extend between the tapered, nose end and the lateral wall for receiving fusion material therebetween;
• the interior surface of the implant body further including an interior surface portion on another side of the lateral wall opposite the one side of the lateral wall and an interior surface portion of the tail end that are spaced from and face each other, and second interior surface portions of the side walls that are spaced from and face each other and extend between the tail end and the lateral wall for receiving fusion material therebetween;
• a plurality of protrusions extending from the interior surface;
• and
• a plurality of teeth on the superior and inferior faces in the intermediate portion.
