The present invention generally relates to an expandable interbody implant. Specifically, the present invention is an expandable interbody implant having an anterior and posterior wedge and opposing endplates. In some embodiments, a slot parallel to the wedge face may be located on each endplate, with a pin holding the endplates to the respective wedges. Additionally, in some implementations, lateral rails may extend from the anterior wedge to the posterior wedge. Furthermore, the expandable implant may include a locking mechanism configured to prevent unwanted collapse.

The invention provides an inter-body spacer in the form of a vertebral body replacement. The spacer comprises a connector having, axially aligned, a socket and threaded socket. A threaded screw is receivable in the threaded socket of the connector at one side of the screw and an endplate receiving head is provided on the other end of the screw for receiving an endplate perpendicular to the axis. The spacer further comprises a cylindrical extension with one end rotatably receivable in the socket of the connector and an endplate receiving head on the other end of the extension for receiving an endplate perpendicular to the axis. A locating formation is provided on each endplate receiving head for locating the endplate at a specific angle about the axis. The spacer further comprises a selection of one or more end plates receivable on the endplate receiving head with the tissue engaging surface of the endplates being transverse to the axis of the spacer at differing angles. The invention also extends to a elongate thoracolumbar lateral plate.
