    Abstract: An expandable implant having superior and inferior endplates disposed on opposite sides of a core is disclosed. The superior endplate may include a first screw engagement surface disposed on a proximal end thereof and the inferior endplate may include a second screw engagement surface disposed on a proximal end thereof. A pin may extend through corresponding pin apertures of the superior endplate, the inferior endplate, and the core.
