Paragraph Number

95

Insertion of the screw member 400 and activation of the driver 162 (head 404 and drive recess 502) expands the upper plate 110 and the lower plate 120 away from each other along the cephalad-caudal axis 520 by expanding the first mesh 360 and the second mesh 362 and moves the first wall 350 and the second wall 352 away from each other along a medial-lateral axis 530 by expanding the upper mesh 370 and the lower mesh 380. 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) and the first wall 350 and the second wall 352 to separate to fill more space between the superior vertebral body and the inferior vertebral body.
