Abstract
An expandable implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed by an external surgical tool. The superior endplate may include a first core having a distal engagement surface and the inferior endplate may a second core having a proximal engagement surface and a threaded screw aperture. The implant may include a threaded locking screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. The implant may include a pair of mounting tangs that may be sheared off and/or recesses. The locking screw may be a break-off screw.
