Abstract
The present invention provides an implant to be implanted between a superior vertebra and an inferior vertebra. The implant comprises a main body having a superior surface and an inferior surface with at least one linear surface protrusion residing on at least one of the superior surface or the inferior surface. The protrusion having a substantially flat bone engaging surface and a generally trapezoidal cross-section.
Claims20
An implant for insertion into a space between a superior vertebra and an inferior vertebra, the implant comprising:
- a main body, the main body comprising at least a superior surface and an inferior surface;
- a plurality of surface protrusions residing on at least one of the superior surface or the inferior surface;
- and
- a plurality of spaces residing on at least one of the superior surface or the inferior surface separating the plurality of surface protrusions, wherein
- the plurality of surface protrusions comprise:
- an anterior facing surface,
- a posterior facing surface,
- a plurality of laterally facing surfaces, and
- a vertebral body engaging surface, such that
- the anterior facing surface and the posterior facing surface converge from the main body to the vertebral body engaging surface and the plurality of laterally facing surfaces converge from the main body to the vertebral body engaging surface.
An implant for insertion into a space between a superior vertebra and an inferior vertebra, the implant comprising:
- a main body, the main body comprising at least a superior surface and an inferior surface;
- a plurality of surface protrusions residing on at least one of the superior surface or the inferior surface;
- and
- a plurality of spaces residing on at least one of the superior surface or the inferior surface separating the plurality of surface protrusions, wherein
- the plurality of surface protrusions comprise:
- an anterior facing surface,
- a posterior facing surface,
- a plurality of laterally facing surfaces, and
- a vertebral body engaging surface shaped to substantially conform with a superior vertebra or an inferior vertebra.
An implant for insertion into a space between a superior vertebra and an inferior vertebra, the implant comprising:
- a main body;
- a superior surface residing on the main body and an inferior surface residing on the main body opposite the superior surface;
- at least one sidewall about the main body connecting the superior surface and the inferior surface;
- an anterior region residing on the main body and a posterior region residing on the main body opposite the anterior region and connected by the at least one sidewall;
- a plurality of linear surface protrusions residing on at least one of the superior surface and the inferior surface, the linear surface protrusions comprising:
- an anterior facing surface,
- a posterior facing surface,
- a plurality of laterally facing surfaces,
- a substantially flat main body engaging surface,
- a substantially flat bone engaging surface opposite the main body engaging surface, and
- the anterior facing surface and the posterior facing surface converging between the substantially flat main body engaging surface to the substantially flat bone engaging surface and the plurality of laterally facing surfaces converging between the substantially flat main body engaging surface to the substantially flat bone engaging surface, such that the linear surface protrusion has a generally trapezoidal cross-section in both an anterior to posterior direction and a lateral direction.
