Abstract
An interbody endcap includes a wall having a first surface connected to an interbody implant and a second surface including an arcuate portion configured for engagement with a vertebral endplate surface. The second surface extends outwardly from the interbody implant to at least adjacent a perimeter of the vertebral endplate surface. Systems and methods are disclosed.
Claims20
An interbody endcap comprising:
- a wall having a first surface connected to an interbody implant and a second surface including an arcuate portion configured for engagement with a vertebral endplate surface when the interbody endcap and a second endcap that is coupled to the interbody implant are each in contact with vertebral endplate surfaces, the wall having an opening that extends through the first and second surfaces and a first mating part positioned within the opening that is configured to engage a second mating part of the interbody implant,
- wherein the second surface extends outwardly from the interbody implant to at least adjacent a perimeter of the vertebral endplate surface.
An interbody endcap comprising:
- a wall having a first surface including a first mating part disposed for engagement with a second mating part of an interbody implant such that the first surface is aligned with the interbody implant such that the wall is disposable in an interlocking configuration with the interbody implant,
- wherein at least one of the mating parts includes a relatively movable member that is engageable with the other of the mating parts to dispose the wall and the interbody implant in the interlocking configuration, the wall further having a second surface configured for engagement with a vertebral endplate surface, and
- wherein the first mating part includes a plurality of resiliently biased members that are rotatably aligned with a plurality of circumferentially disposed slots of the second mating part for disposal of the wall and the implant in the interlocking configuration.
A spinal implant comprising:
- an interbody implant extending between a first end and a second end;
- a first interbody endcap coupled to the first end having a first surface including a first mating part disposed for engagement with a second mating part of the first end of the interbody implant such that the first surface is aligned with the interbody implant such that the first interbody endcap is disposable in an interlocking configuration with the interbody implant, wherein at least one of the mating parts includes a relatively movable member that is engageable with the other of the mating parts to dispose the first interbody endcap and the interbody implant in the interlocking configuration, the first interbody endcap further including a second surface including an arcuate portion configured for engagement with a first vertebral endplate surface when the first interbody endcap and a second endcap that is coupled to the second end of the interbody implant are each in contact with vertebral endplates, wherein the second surface extends outwardly from the interbody implant to at least adjacent a perimeter of the first vertebral endplate surface and the first mating part is positioned within an opening that extends through the first and second surfaces;
- and
- a second interbody endcap having a first surface connected to the second end of the interbody implant and a second surface including an arcuate portion configured for engagement with a second vertebral endplate surface, wherein the second surface extends outwardly from the interbody implant to at least adjacent a perimeter of the second vertebral endplate surface.
