An expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.

Expandable implant

An expandable implant () includes top and bottom plates () having angled inner surfaces () that interact with expansion members (). The expansion members () may be situated on an actuator (), and may include at least one vertical projection () for interacting with a recess () in the plates (). In some instances, rotation of the actuator () in opposing directions about a longitudinal axis may cause the expansion members () to move toward or away from one another, thereby resulting in separation or collapse of the top and bottom plates (). Pins () may also be associated with the expansion members () and received in respective slots () in the plates ().
