1. An expandable interbody spacer for placement between adjacent vertebrae comprising:
two or more upper endplates, each endplate having two or more upper compound-angle linear rods extending from a bottom surface;
two or more lower endplates, each endplate having two or more lower compound-angle linear rods extending from a top surface;
a frame having multiple compound-angle bores configured to slidingly couple with at least one of upper and lower compound-angle linear rods of each upper and lower endplates;
a housing having multiple compound-angle bores configured to slidingly couple with at least one of the upper and lower compound-angle linear rods of each the upper and lower endplates;
wherein movement of the frame and housing toward each other slides the upper compound-angle linear rods and lower compound-angle linear rods outwardly from the compound-angle bores to move the upper and lower endplates simultaneously away from each other both vertically and horizontally to expand both a height and a width of the expandable interbody spacer from a collapsed state to an expanded state.
