description A unibody implant movable between an expanded position and a contracted position is disclosed. The unibody implant may include a unitary expandable body defined by an inferior portion and a superior portion that are connected together. In various embodiments, a set screw may be rotatably supported by the body and configured to move a plug having a first inclined surface facing the distal side. In various embodiments, the set screw may be movable in the longitudinal direction towards the distal side upon rotation of the set screw along the rotation axis, for example. In various embodiments, movement of the set screw urges the plug against the superior portion thereby expanding a vertical distance between the superior and inferior sides of the body. In some embodiments, the plug may include a stabilizing element configured to transfer compressive forces between the superior portion and inferior portion.
