- Fig. la shows an embodiment of the implant 100 of the invention.
- the implant 100 has a first part or plate 110 that is configured to mate with a first vertebra and a second part or plate 120 that is configured to mate with a second vertebra.
- the first plate 110 is an upper plate and the second plate 120 is a lower plate.
- a third part 130 that sits between the first plate 110 and the second plate 120 is also provided.
- the third part 130 acts as a spacer between the first plate 110 and the second plate 120 and facilitates pivotal or rotational and also twisting movement of the first plate 110 and the second plate 120, relative to each other.
- the third part 130 is in the form of a crossbar as discussed in more detail below.
- the upper plate 110 has a first surface 112 from which a keel 114 extends with teeth 115.
- the teeth in this embodiment point forward or anteriorly when the embodiment is meant to be put into a slot in a vertebral body from the anterior of the spine.
- the teeth in an alternative embodiment would point rearward or posteriorly when the embodiment is meant to be put into a slot in a vertebral body from the posterior of the spine.
- the first surface 112, or upper surface abuts the vertebral body when the implant 100 is implanted.
- the first keel 114 extends into the vertebral body to anchor the implant into position.
- the second surface 116, or lower surface engages the spacer 130 of the implant and faces the second plate 120.
- the second surface 116 can form a planar surface that is parallel to the first surface 112, or can form a planar surface that is not parallel to the first surface 112.
- planar surfaces corresponding to the first surface 112 and the second surface 116 of the first plate 110 lie within, or substantially within, the axial plane of the body, while the first keel 114 (which is at or near a 90° angle from the surfaces 112, 116) is aligned within the sagittal plane of the body.
- the lower plate 120 has a first surface 122 from which a keel 124 extends with teeth 125.

- the second surface 126 can form a planar surface that is parallel to the first surface 122, or can form a planar surface that is not parallel to the first surface.
- the first surface 112 of the first plate 110 can be parallel to the first surface 122 of the second plate 120 when the implant 100 is assembled and is in a neutral position (i.e., the position where the first plate 110 has not rotated relative to the second plate 120).
- the first surface 112 of the first plate 110 can be non-parallel to the planar surface of the first surface 122 of the second plate 120 when the implant 100 is assembled and in a neutral position.
- planar surfaces corresponding to the first surface 122 and the second surface 126 of the second plate 120 lie within, or substantially within, the axial plane of the body while the second keel 124 (which is at or near a 90° angle from the surfaces 122, 126) is aligned within the sagittal plane of the body.

- the spacer 130 separates the first plate 110 from the second plate 120.
- Fig. lc shows a top view of the upper plate 110 with the upper surface 112 and the upper keel 114.
- the perimeter shape of the upper plate 110 can be configured to correspond to the perimeter shape of a vertebral disk. This is particularly advantageous where a single implant is placed between two vertebral bodies from an anterior approach.
- the perimeter shape of the upper plate 110 and the lower plate 120 can be the same.
- Fig. Id and Fig. le show an embodiment of the first or upper plate 110 of the implant 100 of the invention.
- the upper plate 110 has a second surface 116 having a channel 150 therein.
- the spacer includes a beam which can be placed into the channel 150 in order to allow the first and second plates of the assembled implant to pivot or rotate relative to each other.

- lh is a cross-section of the upper plate 110 and the lower plate 120 taken along the lines H-H of Fig. la. As shown in Fig. lh, the second surface 116 of the first plate 110 faces the second surface 126 of the second plate 120.
- Fig. 2a is an upper view of an embodiment of a crossbar or spacer 130 of the implant of the invention.
- the crossbar 130 has a first beam 210 and a second beam 220.
- Each beam 210, 220 has a first end 212, 222, and a second end 214, 224, and a midpoint 216, 226, respectively.
- Fig. 2b shows a side view of a crossbar 130 of the implant 100 of the invention.
- the first beam 210 can be configured to sit above the second beam 220.
- Fig. 2c shows the crossbar 130 of the implant of the invention from a bottom view with the first beam 210 configured to sit above the second beam 220.
- the first beam 210 can be configured to be positioned transversely along the length of the second beam 220 at a point preferably corresponding about the midpoint 226 of the second beam 220.
- the second beam 220 can be configured to be positioned along the length of the first beam 210 at a point preferably corresponding about the midpoint 216 of the first beam 210. Where both beams are positioned at the respective midpoints 216, 226 the crossbar forms a "+".
- the first beam 210 can also be configured to be positioned transversely along the length of the second beam 220 at a point corresponding to a location between the midpoint 226 and an end (222, 224).
- the second beam 220 can be configured to be positioned transversely along the length of the first beam 210 at a point corresponding to about the midpoint 216 of the first beam 210. Where one beam 210, 220 is positioned along the length between the midpoint and an end of the other beam, the crossbar forms "T".
- the first beam 210 can be formed integrally with the second beam 220 such that is unitary in construction. Alternatively, the first beam 210 can be adhered to the second beam 220 using a suitable method, such as spot welding.
- Fig. 2d shows a perspective view of a crossbar or spacer 130 of the implant of the invention. As shown in Fig. 2d, the first beam 210 and the second beam 220 are configured so that the second beam 220 is positioned along the length of the first beam 210 at a point between the midpoint 226 of the second beam 220 and an end 222 of the second beam 220.
- the implant 100 has a first plate 110 that is configured to mate with a first vertebra and a second plate 120 that is configured to mate with a second vertebra.
- a crossbar 130 that sits between the first plate 110 and the second plate 120 is also provided.
- the upper beam 210 is placed in the channel 150 of the upper plate 110 such that the upper beam is about perpendicular to the keels 114 and 124.
- the upper beam is positioned toward the posterior of the implant 100.
- the upper beam can be positioned midway between the posterior and the anterior of the implant 100.
- the lower beam 220 is placed in the channel 160 of the lower plate 120 such that the lower beam is about parallel to the keels 114 and 124.
- the crossbar 130 acts as a spacer between the first plate 110 and the second plate 120 and facilitates pivotal or rotational movement of the first plate 110 and the second plate 120, relative to each other.
- the implant 100 placed between vertebral bodies of a patient, the keels 114 and 124 are directed along a posterior to anterior line or in the sagittal plane of the patient. Accordingly as the patient bends forward or backward the upper plate 110 can pivot or rotate about the beam 210.
- the lower beam 220 can pivot or rotate in the lower channel 160, allowing the upper beam 210 to pivot or rotate about the lower beam 220 and also allowing the upper plate 110 to pivot or rotate about the lower beam 220, and, thus, relative to the lower plate 120.
- there is a loose fit between the spacer 130 and the first and second plates and, in particular, there is a loose fit between the upper beam 210 and the upper channel 150 and also between the lower beam 220 and the lower channel 160.
- This loose fit allows for a twisting motion about an axis that is perpendicular to the plates as, for example, perpendicular to the surface 112 of the upper plate.
- this loose fit allows for twisting about the length of the spine.
- the ridge 127 adjacent to the second surface 126 of the lower plate is not parallel to the first surface 122 of the lower plate nor to the upper plate.
- the orientation of the plates 110, 120 in Figs, la, lb and 3, show the implant 100 assembled in a neutral position (i.e., the position where the first plate 110 has not rotated relative to the second plate 120).
- the distance between the first plate 110 and the second plate 120 enable the implant to achieve movement in forward, backward, lateral and rotational directions.
- FIG. 4 shows a side view of an implant 100 of the invention implanted between two vertebrae 410, 420.
- first plate 110 and the second plate 120 at its anterior end A and its posterior end P i.e., the distance between the plates is greater at the anterior A end than the posterior P end
- forward (bending) movement is facilitated to a greater degree than backward (bending) movement.
- an example of a forward bending movement of up to 10° can be achieved while a backward bending movement of 5° will be achieved.
- the amount of backward bending can be increased.
- the implant can be made of titanium or a stainless steel that is approved for implantation into a patient. Other materials that have appropriate structural strength and that are suitable for implantation into a patient can also be used.
- Fig. 6 is a block diagram showing the basic steps of the method of inserting the implant 100 of this invention. First the spine is exposed 610, then the intervertebral disk is removed 620 and the implant is inserted 630. Finally, the wound is closed 640. This procedure can be followed for either an anterior approach or posterior-lateral approach. Additional steps, such as cutting channels into the vertebral bodies to accept the keels of the plates and assembling the implant by inserting the crossbar member between the upper and lower plates prior to installation can also be performed without departing from the scope of the invention.
