Abstract
In accordance with at least one aspect of this disclosure, a disc replacement implant includes, a first endplate configured to engage a vertebral endplate of a first vertebra adjacent an intervertebral space, a second endplate configured to engage a vertebral endplate of a second vertebra opposite the first end plate in the intervertebral space, a core between the first and second endplates, and an annulus surrounding the core and connecting a perimeter of the first endplate to a perimeter of the second end plate. In embodiments, the annulus can include a portion that extends inwardly between the first and second core plates to the spacer.

A disc replacement implant comprising:
- a first endplate configured to engage a vertebral endplate of a first vertebra adjacent an intervertebral space;
- a second endplate configured to engage a vertebral endplate of a second vertebra opposite the first end plate in the intervertebral space;
- a core between the first and second endplates;
- and
- an annulus surrounding the core and connecting a perimeter of the first endplate to a perimeter of the second end plate.
A disc replacement tool comprising:
- a main shaft defining a proximal end and an opposed distal end;
- an inserter head extending from the distal end of the main shaft;
- an actuating knob at the proximal end of the main shaft;
- a rotation shaft extending from the knob through the main shaft to the inserter head;
- and
- a set of male threads in the inserter head operatively connected to be rotated around a thread axis of the threads by the rotation shaft for releasing a disc replacement implant from the inserter head.
