INTERBODY IMPLANT WITH GRAFT RETAINING BONE CAP
Systems and methods for retaining bone graft material in an interbody implant system are provided. In one embodiment of the invention, there is provided an interbody implant system comprising an implant device and at least one sliding bone cap device. The implant device includes a body defining a cavity for holding bone graft material therein and a plurality of fenestrations on at least one surface of the body to allow bone to grow through the body of the implant. The implant is connectable to at least a portion of the at least one sliding bone cap, wherein once connected, the at least one sliding bone cap prevents the bone graft material from being expelled from the body of the implant during insertion of the implant into the interbody disc space.
1 . An interbody implant system comprising:
an implant device including
a body defining at least one cavity for holding graft material therein; and
a plurality of openings on at least one side to allow bone to grow through the implant device;
at least one bone cap device comprising a plurality of openings on at least one side to allow bone to grow through the implant,
wherein the implant device is connectable to at least a portion of the at least one bone cap device and wherein once connected, the bone cap device prevents the graft material from being expelled from the implant during insertion of the implant into the disc space.
