For example, if the expandable intervertebral implant is embodied as the expandable intervertebral implant 200 of Figures 2A,2B having a first lattice 130, a second lattice 140, a solid upper plate 110, a solid lower plate 120, insertion of the screw member 400 into the opening 150 deforms the first lattice 130 and the second lattice 140. The first lattice 130 and the second lattice 140 deform because the cross-sectional diameter of the screw member 400 is greater than a height of the opening 150. Insertion of the screw member 400 and deformation of the first lattice 130 and the second lattice 140 expands the upper plate 110 and the lower plate 120 away from each other along the cephalad-caudal axis 520. This expansion may cause the upper plate 110 to engage a superior vertebral body (not shown) and the lower plate 120 to engage an inferior vertebral body (not shown). Activation of the driver 162 separates the upper plate 110 from the lower plate 120 by deforming the first lattice 130 and the second lattice 140.
