Alternatively, or in addition, a single expandable intervertebral implant may be available and the expansion mechanism 160 may include a set of screw members 400. Each member of the set of screw members 400 may have a different cross-sectional diameter. In one embodiment, a surgeon may use a plurality of screw member 400 from the set of screw members 400 to expand the expandable intervertebral implant. For example, the surgeon may start with a screw member 400 having a smaller diameter, insert this screw member 400, remove the smaller diameter screw member 400, and then insert progressively larger diameter screw members 400 until an optimal level of expansion is achieved.
