31. An intervertebral implant according to claim 28, wherein the recess in the lower part is a generally flat surface with three walls including two opposite side walls and an end wall and including an opening opposite the end wall.
32. An intervertebral implant according to claim 31, wherein the second upper piece of the lower part includes a means for snap fitting into the first lower piece of the lower part.
It should already be noted here that the words �lower part� and �upper part� do not necessarily say anything about the installed position of the intervertebral implant in the spinal column; the part called the �lower part� could in fact be above in the spinal column. What is essential is merely that the upper part and lower part define the intervertebral implant on opposite sides of the implant.
The intervertebral implant 1 shown in the drawing includes three parts, namely a platelike upper part 2, a platelike lower part 3, and a substantially platelike pivot insert 4.
The upper part 2 is embodied flat on its top, thus creating a support face 5, on which various kinds of protrusions 6, 7 are disposed which serve the purpose of anchoring the upper part 2 in a vertebra that rests, with its end face toward an intervertebral space, on the support face 5.
After the introduction of the upper part 2 and lower part 3 in this way, the two parts of the intervertebral implant 1 can be spread apart; that is, their spacing is increased, for instance with the aid of the manipulation instrument that is holding the upper 2 and the lower part 3.
The upper part 2 and lower part 3 are preferably made of physiologically safe metal, such as titanium, while the pivot insert 4 preferably comprises a likewise physiologically safe plastic material, such as polyethylene.
These support faces 5 and 13 can be embodied in an especially bone-compatible way; for instance, this surface can be roughened by a coating, so that optimal anchoring to the adjacent bone material is obtained.
As shown in the figures, the anchors 6 and 14 each have a zigzag edge which comprise teeth. As best shown in FIG. 7, anchor 6 is greater in height than the remainder of the upper part 2, i.e., from surface 5 to the bottom of protrusion 10. Similarly, anchor 14 is greater in height than the remainder of the lower part 3, i.e., from lower surface 13 to the top of walls 16, 17 and 18. As also shown in the figures, in the preferred embodiment, the length of the anchors 6 and 14, i.e., in the direction from the anterior to the posterior thereof, is greater than one half of the overall dimension of its respective part from its anterior to its posterior, passing through that anchor. As also noted in the figures, the vertical height of each anchor 6 and 14 is greater than its width which is the dimension taken horizontally in FIG. 5 or 7.
As best shown in FIGS. 2, 4 and 5, in the absence of pivot insert 4, the protrusion 10 of upper part 2 can fit down between walls 16, 17 and 18 of the lower part 2. This fitting of protrusion 10 within the recess 19, surrounded by walls 16, 17 and 18 may be referred to as �nesting� since the protrusion 10 essentially �nests� within recess 19. With the upper and lower parts in this nested condition, as shown in FIGS. 4 and 5, the combined height of the upper and lower parts 2 and 3, i.e., the height from surface 13 to surface 5, is less than the total additive height of the upper and lower parts, taken separately, I.e., less than the total of the height from surface 13 to the top of walls 16, 17 and 18 plus the height from surface 5 to the bottom of protrusion 10.
To reach its final destination within an intervertebral space, the implant must of course be moved along a path, i.e., an insertion direction from outside of the patient, into the patient, and then into the intervertebral space. In the illustrated embodiment, as described above, instruments would engage apertures 20, 21, 22 and 23 to move the implant along a path in an insertion direction. The anchors 6 and 14 are parallel to this path. As a point of reference, lateral planes parallel to the direction of this path pass through the outermost boundaries of the implant which, in the preferred embodiment, would be the opposed side surfaces of the parts. Thus, in the illustrated embodiment, the path would be parallel to the front to rear (anterior to posterior) direction, wherein, during insertion, the rear (posterior) of the implant would constitute the lead end and the front (anterior) thereof would constitute the trailing end.
