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
An intervertebral implant for implantation in an intervertebral space between vertebrae, the implant comprising:
- a solid upper outer rim and a solid upper inner rim, the upper outer and inner rims defining an upper surface;
- a solid lower outer rim and a solid lower inner rim, the lower outer and inner rims defining a lower surface;
- a front end, a rear end and opposed sidewalls extending between the ends and between the upper inner and outer rims and lower inner and outer rims;
- each of the sidewalls including at least one solid x-shaped strut having a pair of arms defining upper arm ends and lower arm ends, the arm ends of the x-shaped strut extending between the upper outer rim and the lower outer rim;
- and
- a porous structure integrally formed in the sidewalls with the solid upper rims, the solid lower rims, and the at least one solid x-shaped strut in each sidewall, the implant being formed as a single 3-D printed structure.
An intervertebral implant for implantation in an intervertebral space between vertebrae, the implant comprising:

- a solid lower outer rim and a solid lower inner rim, the lower outer and inner rims defining a lower surface;
- a front end, a rear end and opposed sidewalls extending between the ends and between the upper inner and outer rims and lower inner and outer rims;
- a plurality of cross struts extending between the upper outer rim and the upper inner rim, and between the lower outer rim and the lower inner rim;
- each of the sidewalls including at least one solid outer x-shaped strut having a pair of arms defining upper arm ends and lower arm ends, the arm ends of the x-shaped strut attached between the upper outer rim and the lower outer rim;
- each of the sidewalls including at least one solid inner x-shaped strut whose arm ends are attached between the upper inner rim and the lower inner rim;
- and
- a porous structure integrally formed in the sidewalls with the solid upper rims, the solid lower rims, the cross struts and the x-shaped struts, the implant being formed as a single 3-D printed structure and the porous structure being greater than 50% open.
