In addition, or alternatively, the upper mesh 370 and lower mesh 380 may each include a second pattern. The second pattern may be the same as the first pattern or the first pattern and the second pattern may each be different. The first pattern and the second pattern may each be selected such that activation of the driver 162 of the expansion mechanism 160 causes a first predetermined increase in a distance, such as (Δ H = height 580’ – height 580, or h1 + h2), between the upper plate 110 and the lower plate 120 that differs from a second predetermined increase in a distance, such as (Δ W = width 590’ – width 590, or w1 + w2), between the first wall 350 and the second wall 352. By using a different pattern for the upper lattice 310 and lower lattice 320 from a pattern used for the first lattice 130 and second lattice 140 an amount of expansion along a cephalad-caudal axis 520 and a medial-lateral axis 530 can each be independently managed or determined.
