Claim 13:
14. A method of implanting an expandable interbody device between adjacent vertebrae comprising:
positioning the expandable interbody device between adjacent vertebrae, wherein the expandable interbody device comprises:
an upper structure;
a lower structure configured to slideably couple with the upper structure;
a screw mechanism between the upper structure and the lower structure, wherein the screw mechanism comprises a proximal section and a distal section, wherein the proximal section comprises first threads wound in a first direction configured to engage a proximal threaded hole in the coupler, and the distal section comprises second threads wound in a second direction, opposite the first direction, configured to engage a distal threaded hole in the coupler; and
a coupler, wherein the coupler comprises a proximal side configured to engage the proximal section and a distal side configured to engage the distal section;

rotating the screw mechanism to change a length of the screw mechanism from a first length to a second length which causes a distance between the upper structure and the lower structure to change from a first distance to a second distance to form a chamber; and
injecting material into the chamber.
