Abstract
An interbody endcap comprises at least one member configured for connection with an interbody implant. The at least one member has a thickness that permits bone growth therethrough and a uniform surface configuration that resists and/or prevents egress of bone graft from a cavity of the interbody implant. Systems and methods are disclosed.
Claims19
An interbody implant comprising:
- a body comprising opposite top and bottom surfaces that are each configured to engage a vertebra, the body including an inner surface defining a cavity, the cavity including a first opening that extends through the top surface and a second opening that extends through the bottom surface;
- and
- at least one member positioned within one of the openings so as to block a portion of one of the openings, the at least one member having a thickness that permits bone growth therethrough and a surface configuration that resists and/or prevents egress of bone graft from the cavity,
- wherein the inner surface defines a recess that extends about the cavity, the recess including linear and arcuate portions, the at least one member being disposed in the recess.

A spinal implant comprising:
- an interbody implant extending between a first end and a second end, the ends extending between opposite top and bottom surfaces, an inner surface of the implant defining a cavity, the implant having a first opening that extends through the top and a second opening that extends through the bottom surface, the openings being in communication with the cavity;
- a first endcap member disposed in the first opening such that the first endcap member blocks a portion of the first opening;
- and
- a second endcap member disposed in the second opening such that the second endcap member blocks a portion of the second opening, each of the endcap members having a thickness that permits bone growth therethrough and a uniform surface configuration that resists and/or prevents egress of bone graft from the cavity,
- wherein the inner surface defines a recess that extends about the cavity, the recess including linear and arcuate portions, the first endcap member being disposed in the recess.

- a first endcap member positioned within the first opening so as to block a portion of the first opening, the first endcap member comprising opposite first and second surfaces;
- and
- a second endcap member positioned within the second opening so as to block a portion of the second opening, the second endcap member comprising opposite first and second surfaces, the endcap members each having a thickness that permits bone growth therethrough and a surface configuration that resists and/or prevents egress of bone graft from the cavity,
- wherein the first endcap member includes a male mating part extending outwardly from the second surface of the first endcap member and the second endcap member includes a female mating part extending outwardly from the second surface of the second endcap member that engages the male mating part to couple the endcap members to one another.
