<p>An expandable intervertebral fusion device is provided including a core, an upper endplate for contacting a first vertebral body and a lower endplate for contacting a second vertebral body. The expandable intervertebral fusion device is configurable in a first state, a second state and a third state. In the first state, the upper and lower endplates are generally planar to one another and define a first height. In the second state, the upper and lower endplates remain generally planar to one another and define a second height greater than the first height. In the third state, a lordotic angle is defined between the upper and lower endplates.</p> |
