Abstract

An orthopedic implant system includes an intervertebral implant. The implant includes a body having an upper surface extending generally in a first plane. The upper surface has a first plurality of longitudinal grooves and a second plurality of transverse grooves extending therealong. Portions of the upper surface extend between adjacent longitudinal grooves and transverse grooves form individual peaks. A lower surface extends generally in a second plane, parallel to the first plane. The lower surface has a third plurality of longitudinal grooves and a fourth plurality of transverse grooves extending therealong. Portions of the lower surface extend between adjacent longitudinal grooves and transverse grooves form individual peaks.

Claims

1. An orthopedic implant system comprising an intervertebral implant comprising a body having:

an upper surface extending generally in a first plane, the upper surface having a first plurality of longitudinal grooves and a second plurality of transverse grooves extending therealong, wherein portions of the upper surface extending between adjacent longitudinal grooves and transverse grooves form individual peaks; and

a lower surface extending generally in a second plane, oblique to the first plane, the lower surface having a third plurality of longitudinal grooves and a fourth plurality of transverse grooves extending therealong, wherein portions of the lower surface extending between adjacent longitudinal grooves and transverse grooves form individual peaks.

2. The orthopedic implant system according to claim 1, wherein each individual peak further comprises an osteoconductive material.

3. The orthopedic implant system according to claim 1, further comprising a side wall extending between the upper surface and the lower surface, the side wall having an anterior portion and a posterior portion, each of the anterior portion and the posterior portion having a radiopaque portion.

4. The orthopedic implant system according to claim 1, wherein the body has a generally centrally located cavity extending therethrough between the upper surface and the lower surface.

5. The orthopedic implant system according to claim 4, wherein the body further comprises a side wall extending between the upper surface and the lower surface, wherein the side wall further comprises a recess extending from the side wall inwardly toward the centrally located cavity and an implant aperture extending between the side wall and the centrally located cavity.

6. The orthopedic implant system according to claim 5, wherein the recess is defined by at least one straight line segment.

7. The orthopedic implant system according to claim 6, further comprising an insertion instrument releasably couplable to the intervertebral implant, the insertion instrument having a fastener portion releasably couplable to the aperture, the insertion instrument further having an extension portion, adjacent to the fastener portion, the extension portion being releasably insertable into the recess.

8. The orthopedic implant system according to claim 6, further comprising a generally planar plate couplable to the intervertebral implant, the plate having an extension portion insertable into the recess, the extension portion having a generally straight portion adapted to engage the at least one straight line segment when the extension portion is inserted into the recess.

9. The orthopedic implant system according to claim 8, wherein the plate further comprises a plurality of screw recesses extending therethrough such that, when the plate is coupled to the intervertebral implant, a first of the plurality of recesses extends above the upper surface and a second of the plurality of recesses extends below the lower surface.

10. The orthopedic implant system according to claim 9, wherein each of the plurality of screw recesses comprises a cylindrical portion extending inwardly therefrom.

11. The orthopedic implant system according to claim 10, further comprising a screw insertable into each of the plurality of screw recesses, each screw comprising:

a screw head; and

a plurality of cantilever segments extending around the screw head,

wherein, as each screw is inserted into its respective screw recess, the plurality of cantilever segments engage the cylindrical portion and bias inwardly toward the screw head and, after the cantilever segments pass the cylindrical portion, the cantilever segments bias outwardly away from the screw head underneath the cylindrical portion.

12. The orthopedic implant system according to claim 10, further comprising a screw insertable into each of the plurality of screw recesses, each screw comprising a shaft having a distal portion and a proximal portion, wherein the distal portion has a distal thread having a first pitch and the proximal portion has a proximal thread having a second pitch, the proximal pitch being less than the distal pitch.

13.

14. The orthopedic implant system according to claim 8, further comprising an implant body extension releasably couplable to the plate, the implant body extension containing indicia imprinted thereon, the indicia providing identification information for the intervertebral implant.

15. The orthopedic implant system according to claim 8, wherein the plate further comprises an attachment aperture extending therethrough such that the attachment aperture extends co-axially with the implant aperture.

16. An orthopedic implant system comprising:

an intervertebral implant comprising a body having;

an upper surface having a generally convex shape in an anterior-posterior direction;

a plurality of lower peaks extending downwardly from the lower surface, each of the lower peaks having a side extending generally perpendicular to the lower surface, wherein adjacent lower peaks in the anterior-posterior direction have lower surfaces extending generally parallel with respect to each other.

17. The orthopedic implant system according to claim 16, further comprising a plate releasably couplable to the body such that, when the plate is coupled to the body, the plate has a first screw recess extending above the upper peaks and a second screw recess extending below the peaks.

18. The orthopedic implant system according to claim 17, further comprising:

a screw insertable through each screw recess; and

an implant body extension releasably couplable to the proximal portion of each screw, the implant body extension containing indicia imprinted thereon, the indicia providing identification information for the intervertebral implant.

19. The orthopedic implant system according to claim 16, further comprising an insertion tool having a retractable engagement extension releasably insertable into the body between the upper surface and the lower surface.

20. An orthopedic implant system comprising:

an intervertebral implant comprising a body having;

an upper surface;

a first plurality of upper peaks extending away from the upper surface, each of the upper peaks having a plurality of sides extending generally away from the upper surface, wherein at least one of the sides has a porous coating applied thereto;

a lower surface; and

a second plurality of lower peaks extending away from the lower surface, each of the lower peaks having a plurality of sides extending away from the lower surface, wherein at least one of the sides has a porous coating applied thereto.
