Abstract
A spinal fixation system includes an expandable disc replacement body and an angle-setting disc replacement holder. The expandable disc replacement body includes a first wall, a second wall, and a hinge connecting the first wall and the second wall. An insertion instrument may be used to implant the expandable disc replacement body into a subject. The disc replacement holder is positioned between the first wall and the second wall, and an angle and/or height between the first wall and the second wall can be varied by adjustment of the disc replacement holder and locked into place using locking mechanisms.
