Abstract
An expandable implant assembly includes an upper endplate assembly, a lower endplate assembly, and a control assembly. The upper endplate assembly is configured to engage bone and includes an upper base member and a plurality of upper endplates. Each of the plurality of upper endplates is coupleable to the base member. The lower endplate assembly is configured to engage bone and includes a lower base member and a plurality of lower endplates. Each of the plurality of lower endplates is coupleable to the base member. The control assembly is configured to couple the upper endplate assembly to the lower endplate assembly and control movement of the upper endplate assembly relative to the lower endplate assembly.
Claims18
An expandable implant assembly, comprising:
- an upper endplate assembly configured to engage bone, the upper endplate assembly comprising:
- an upper base member;
- and
- a plurality of upper endplates, wherein each of the plurality of upper endplates is selectively coupleable to the upper base member;
- wherein the upper base member comprises a first graft window, and wherein at least one of the plurality of upper endplates comprises a second graft window configured to be aligned with the first graft window when the at least one of the plurality of upper endplates is coupled to the upper base member;
- a lower endplate assembly configured to engage bone, the lower endplate assembly comprising:
- a lower base member;
- and
- a plurality of lower endplates, wherein each of the plurality of lower endplates is selectively coupleable to the lower base member;
- and
- a control assembly configured to couple the upper endplate assembly to the lower endplate assembly and control movement of the upper endplate assembly relative to the lower endplate assembly.
An expandable implant assembly, comprising:
- a first endplate assembly configured to engage bone, the first endplate assembly comprising:
- a first base member;
- and
- a first modular endplate coupled to the first base member;
- wherein the first base member includes an interior wall defining a first graft window and the first modular endplate includes a projection defining a second graft window, wherein the projection engages a ridge on the interior wall in a snap fit arrangement;
- a second endplate assembly configured to engage bone, the second endplate assembly comprising:
- a second base member;
- and
- a second modular endplate coupled to the second base member;
- and
- a control assembly configured to couple the first endplate assembly to the second endplate assembly and control movement of the first endplate assembly relative to the second endplate assembly.
A method of configuring an implant, comprising:
- selecting an upper endplate from a plurality of upper endplates;
- selecting a lower endplate from a plurality of lower endplates;
- and
- coupling the upper endplate to an upper base member and coupling the lower endplate to a lower base member to form an implant, the implant comprising:
- an upper endplate assembly comprising the upper endplate and the upper base member;
- a lower endplate assembly comprising the lower endplate and the lower base member;
- a first graft window in the first base member;
- a second graft window in the first endplate that is aligned with the first graft window when the first endplate is coupled to the first base member and
- a control assembly operatively coupling the upper endplate assembly to the lower endplate assembly and configured to control relative movement between the upper endplate assembly and the lower endplate assembly, the control assembly operatively couplable to at least two of the plurality of upper endplates and at least two of the plurality of lower endplates.
