摘要： 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. In various embodiments, the superior endplate and inferior endplate are hingedly connected to the core via the pin. The implant may include a locking screw movable between a locked position and an unlocked position. In the locked position, the locking screw may urge an engagement surface of the superior endplate and inferior endplate such that corresponding interior surfaces of the superior and inferior endplates frictionally engage against a corresponding exterior surface of the core.
