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.
Claims15
A corpectomy implant comprising:
- a solid inner cylindrical member defining a hollow inner chamber and having a first end plate adapted to engage a surface of a first vertebral body;
- an outer cylindrical member defining a hollow inner chamber and having a second end plate adapted to engage a surface of a second vertebral body, the outer cylinder cylindrical member telescopingly receiving the inner cylindrical member;
- a porous structure disposed in the inner chamber of the solid inner cylindrical member for encouraging bone growth, wherein the inner cylindrical member and the porous structure are 3D printed structures containing the same 3D printing material and the porous structure is formed integrally with the inner cylindrical member.
A corpectomy implant comprising:
- a solid inner cylindrical member defining a hollow inner chamber and having a first end plate adapted to engage a surface of a first vertebral body, the inner cylindrical member having an outer threading;
- an outer cylindrical member defining a hollow inner chamber and having a second end plate adapted to engage a surface of a second vertebral body, the outer cylindrical member telescopingly receiving the inner cylindrical member, the inner and outer cylindrical members adapted to be positioned in a space occupied by a removed vertebral body;
- a 3D printed porous structure disposed in the inner chamber of the solid inner cylindrical member, wherein the inner cylindrical member and the porous structures contain the same 3D printing material and the porous structure is formed and 3D printed integrally with the inner cylindrical member.
