Claim Text:
1. An expandable implant comprising: an upper endplate; a lower endplate, wherein at least one of the upper endplate and the lower endplate include a bore hole for receiving a bone fastener therethrough; an actuator positioned between the upper endplate and the lower endplate; and an actuator screw for actuating the actuator, wherein rotation of the actuator screw causes movement of the actuator, thereby causing expansion or contraction of the implant wherein the actuator includes a frame rotatably supporting the actuator screw and a translation member, wherein as the actuator screw rotates within the frame, the translation member moves within the frame from a first position to a second position by cooperation between threads upon the actuator screw and mating threads of the translation member, wherein the translation member is supported within the frame by at least two support screws engaged with the translation member and passable through respective channels formed in the frame, wherein the actuation screw extends from a proximal end of the translation member through a distal end of the translation member and contacts an inner surface of the frame.
