Abstract
An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body extending from an upper surface to a lower surface. The body has a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear walls such that an internal chamber is defined within the front and rear ends and the first and second walls. The body defines an outer perimeter and an inner perimeter extending about the internal chamber. At least one of the side walls is defined by an integral porous structure.
Claims20
An intervertebral implant for implantation in an intervertebral space between vertebrae, the implant comprising:
- a body extending from an upper surface to a lower surface, the body having a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear ends such that an internal chamber is defined within the front and rear ends and the first and second side walls, the body defining an outer perimeter and an inner perimeter extending about the internal chamber, the body having a solid structure comprising a first outer rim, a first inner rim, a second outer rim, a second inner rim, a first and second plurality of cross struts, and a solid wall, the first outer n extending about the outer perimeter of the upper surface and the first inner rim extending about the inner perimeter of the upper surface, the second outer rim extending about the outer perimeter of the lower surface and the second inner rim extending about the inner perimeter of the lower surface, the first plurality of cross struts connecting the first outer rim to the first inner rim, the second plurality of cross struts connecting the second outer rim to the second inner rim, and the solid wall connecting the first plurality of cross struts to the second plurality of cross struts;
- and
- a porous structure filling areas between the first and second plurality of cross struts and from the upper surface to the lower surface such that the solid wall is sandwiched in between the porous structure,
- wherein the solid wall is positioned within a portion of one of the first and second plurality of cross struts.

- and
- a porous structure filling areas between the first and second plurality of cross struts and from the upper surface to the lower surface such that the first and second solid walls are sandwiched in between the porous structure
- wherein the solid wall is positioned within a portion of one of the first and second plurality of cross struts.
