Abstract
A spinal implant is provided including an upper surface, a lower surface, a front surface and a back surface, two side surfaces extending between the upper surface and the lower surface, the two side surfaces extending between the front surface and the back surface and an opening positioned closer to the back surface than the front surface. The opening is provided to contain graft material that spans between a cortical rim of the upper vertebral body and the cortical rim of the lower vertebral body. The method includes packing the opening with graft material, wherein the graft material spans between the decorticated cortical rim of the upper vertebral body and the decorticated cortical rim of the lower vertebral body.
Claims20
A spinal implant comprising:
- an upper surface, wherein at least a portion of the upper surface is configured to contact an endplate of an upper vertebral body;
- a lower surface, wherein at least a portion of the lower surface is configured to contact an endplate of a lower vertebral body;
- a front end and a back end, wherein the front end is configured for insertion into a space between the upper vertebral body and the lower vertebral body;
- a first side extending between the upper surface and the lower surface;
- a second side extending between the upper surface and the lower surface;
- a pocket located at the front end, wherein the pocket is partially enclosed by a first flange projecting from the first side and a second flange projecting from the second side, wherein the pocket fully extends from the upper surface to the lower surface to contain graft material from the upper surface to the lower surface,
- wherein, during insertion of the spinal implant, the pocket is configured to contain graft material that spans between a cortical rim of the upper vertebral body and a cortical rim of the lower vertebral body.
