Abstract
An interbody system including an implant and a tool for inserting and expanding the medical implant and locking the implant in place is disclosed. The medical 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. The superior and inferior endplate may include radially disposed and opposed surfaces that mate and/or directly contact each other when a locking screw is threaded through a screw aperture. The implant may include a threaded breakoff 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. When broken, the breakoff screw may comprise a recessed fracture surface.
