1. An expandable interbody device for placement between adjacent vertebrae comprising:
an upper structure;
a lower structure configured to slideably couple with the upper structure; and
a screw mechanism between the upper structure and the lower structure, the screw mechanism comprising:
a proximal section and a distal section; and
a coupler comprising a proximal side configured to engage the proximal section and a distal side configured to engage the distal section;
wherein the proximal section and the distal section are configured to rotate as a unit to change a length of the screw mechanism from a first length to a second length;
wherein the proximal section is configured to engage the upper structure and the lower structure and the distal section is configured to engage the upper structure and the lower structure to move the upper structure and the lower structure from a first distance to a second distance.
