An example medical device suitable for use as an intervertebral spacer includes a main body having an exterior proximal wall, an exterior distal wall, a first exterior lateral wall, a second exterior lateral wall, an upper surface, a lower surface, an interior proximal wall, an interior distal wall, a first interior lateral wall, a second interior lateral wall, and a longitudinal axis. The interior proximal wall, the interior distal wall, the first interior lateral wall, and the second interior lateral wall cooperatively define an interior cavity. The first and second exterior lateral walls are outwardly directed at an angle from the lower surface to the upper surface relative to the longitudinal axis.100 162 141 130 5 13-6 154 102 15220 131 6 160 164 1421 160 198 199 6 112 L- FIG. 1 100 6162 148 154 150 152 110 147 182 180 141 114 116 1 142 18132 FIG 102 .2 140 186 1246 W2 a 184 FIG. 2 E 1141 r3 r,15 r 22 110 14214 11154 3 15 1214 144 122 116 - - 114 136 199 13 17 102 FIG. 3
