1. An intervertebral spacer comprising:
a first expandable support member configured to expand in a first direction;
a second expandable support member configured to expand in the first direction;
a first expander coupled to the first expandable support member, wherein the first expander is configured to rotate relative to the first expandable support member to move the first expandable support member away from a longitudinal axis of the intervertebral spacer, and wherein the first expander is configured to slide along the first expandable support member in a second direction different than the first direction to cause expansion of the first expandable support member in the first direction; and
a second expander coupled to the second expandable support member, wherein the second expander is configured to rotate relative to the second expandable support member to move the second expandable support member away from the longitudinal axis of the intervertebral spacer, and wherein the second expander is configured to slides along the second expandable support member in a third direction different than the first direction to cause expansion of the second expandable support member in the first direction.
