Abstract
An implant assembly including an expandable vertebral body replacement implant. Two outer cores disposed on opposing ends of an inner are configured to move away from each other when the inner core is actuated. The implant assembly may include removable endplate configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant may include a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism may be automatically engage after removal of an inserter instrument from the implant assembly.
Claims18
An implant assembly for engagement between a first vertebral body and a second vertebral body comprising:
- an inner core extending between a first end and a second end;
- a first outer core disposed on the first end;
- and
- a second outer core disposed on the second end,
- wherein the inner core is configured to be actuated in a first direction to move the first outer core and second outer core to an expanded configuration and wherein the inner core is configured to be actuated in a second direction to move the first outer core and the second outer core to a collapsed configuration;
- wherein the first outer core and the second outer core contain one or more mating rails to prevent rotation of the first outer core and the second outer core during expansion.
An implant assembly for engagement between a first vertebral body and a second vertebral body comprising:
- an inner core extending between a first end and a second end;
- a first outer core disposed on the first end;
- a second outer core disposed on the second end;
- a first endplate configured to removably attach to the first outer core;
- a second endplate configured to removably attach to the second outer core;
- wherein the inner core is configured to be actuated in a first direction to move the first outer core and second outer core to an expanded configuration and wherein the inner core is configured to be actuated in a second direction to move the first outer core and the second outer core to a collapsed configuration;
- wherein the first outer core and the second outer core contain one or more mating rails to prevent rotation of the first outer core and the second outer core during expansion.
