A method for separating bones of a joint, the method comprising:
- providing a spacer including:
- a first endplate configured to engage a first bone of the joint,
- a second endplate configured to engage a second bone of the joint,
- tissue engaging projections, wherein the tissue engaging projections each comprise an elongated body portion and a ridge that extends at angle with respect to the elongated body, and
- an actuation subassembly that extends between the first endplate and the second endplate;
- inserting the spacer between the first bone and the second bone of the joint;
- and
- advancing the actuation subassembly to deploy the tissue engaging projections into the first bone and the second bone,
- wherein the actuation subassembly includes a drive nut comprising a head portion and an extension from the head portion, wherein the extension is secured in a cutout formed by the first endplate and the second endplate.
