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 interior 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 a solid support structure and an integral porous structure, the porous structure extending from the outer perimeter to the inner perimeter. The porous structure embeds or encapsulates at least a portion of the solid support structure.
Claims20
A method of implanting a cervical intervertebral implant between adjacent vertebrae, comprising:
- providing a 3D printed cervical intervertebral implant, the cervical intervertebral implant including:
- a body having a front end, a rear end and opposed side walls extending between the ends, the body having an outer perimeter and an inner perimeter about an internal chamber, the body including:
- an upper surface and a lower surface, the upper surface defined by an upper outer rim and a spaced apart upper inner rim and the lower surface defined by a lower outer rim and a spaced apart lower inner rim;
- a front wall extending at the front end between at least the upper outer rim and the lower outer rim;
- a rear wall extending at the rear end between at least the upper outer rim and the lower outer rim;
- each of the side walls including at least one cross strut extending between the upper rims and at least one cross strut extending between the lower rims;
- each of the side walls including at least one support structure extending between the upper surface and the lower surface, the support structure occupying a minimal space within each side wall;
- a porous structure integrally 3D printed with the upper rims, the lower rims, each of the cross struts, and each of the structures in each of the side walls;
- and
- a plurality of struts each extending between the upper outer rim to the lower inner rim;
- at least partially removing a disc between the adjacent vertebrae;
- and
- inserting the cervical intervertebral implant between the adjacent vertebrae to facilitate fusion of the adjacent vertebrae.

- and
- a plurality of struts each extending between the upper outer rim to the lower inner rim;
- at least partially removing a disc between the adjacent vertebrae;
- and
- inserting the cervical intervertebral implant between the adjacent vertebrae to facilitate fusion of the adjacent vertebrae.
