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.
Claims16
A corpectomy implant comprising:
- an inner cylindrical member defining an hollow inner chamber and having a first end plate adapted to engage a surface of a first vertebral body;
- an outer cylindrical member defining an hollow inner chamber and having a second end plate adapted to engage a surface of a second vertebral body, the outer cylinder telescopingly receiving the inner member;
- a gear coupled to both the inner and outer members and adapted to translate the inner member relative to the outer member;
- a porous structure disposed in the inner chamber of the inner cylindrical member for encouraging bone growth.
A corpectomy implant comprising:
- an inner cylindrical member defining an 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 an hollow inner chamber and having a second end plate adapted to engage a surface of a second vertebral body, the outer cylinder telescopingly receiving the inner member and having an inner threading, the inner and outer cylindrical members adapted to be positioned in a space occupied by a removed vertebral body;
- a gear threadingly coupled to the outer threading of the inner member and to the inner threading of the outer member, and adapted to translate the inner member relative to the outer member;
- a 3D printed porous structure disposed in the inner chamber of the inner cylindrical member.
