Claims14
A method for inserting an implant between adjacent vertebral bodies, said method comprising:
- inserting the implant in between the adjacent vertebral bodies in a collapsed position;
- expanding the implant to an expanded position;
- and
- fastening the implant to the adjacent vertebral bodies,
- wherein the implant comprises:
- a first endplate having a longitudinal axis, wherein the first endplate comprises a planar portion with protrusions and an extension portion, and wherein a superior most surface of the first endplate is adjacent a superior one of the adjacent vertebral bodies when the implant is inserted between the adjacent vertebral bodies;
- a second endplate, wherein an inferior most surface of the second endplate is adjacent an inferior one of the adjacent vertebral bodies when the implant is inserted between the adjacent vertebral bodies;
- a first ramped body extending between the first endplate and the second endplate, wherein the first ramped body comprises at least one upwardly facing ramp engaging the first endplate and at least one downwardly facing ramp engaging the second endplate;
- an actuator in engagement with the first ramped body, wherein rotation of the actuator causes translation of the first ramped body, thereby causing the implant to expand into the expanded position;
- and
- a first socket having a first axis, the first socket formed through the extension portion of the first endplate, wherein an entirety of the first socket is superior to the superior most surface of the first endplate and wherein the first axis of the first socket is oblique to the longitudinal axis of the first endplate;
- a first anchor configured to fasten the implant to the adjacent vertebral bodies, wherein the anchor is received in the first socket;
- and
- a first blocking fastener disposed in the extension portion of the first endplate, wherein an entirety of the first blocking fastener is superior to the superior most surface of the first endplate, wherein the first blocking fastener is configured to retain the first anchor in the first socket.

- a first anchor configured to fasten the implant to the patient, wherein the anchor is received in the first socket;
- and
- a first blocking fastener disposed in the extension portion of the first endplate, wherein an entirety of the first blocking fastener is superior to the superior most surface of the first endplate, wherein the first blocking fastener is configured to retain the first anchor in the first socket.
