An expandable fusion device may include a first endplate and a second endplate. The expandable fusion device may also include first and second ramps configured to mate with both the first and second endplates. An inserter instrument includes an outer shaft having a bore extending longitudinally therethrough and an inner shaft extending through the bore in the outer shaft. The outer shaft is configured to engage the first or second opening in the second ramp, and the inner shaft is configured to engage the corresponding first or second opening in the first ramp to control implant height and/or lordotic angle.
