Abstract:
1. A spacer for separating bones of a joint, the spacer comprising: a frame having a longitudinal axis, and having at least one ramped surface; a first endplate configured to engage a first bone of the joint, and having at least one ramped surface mateable with the at least one ramped surface of the frame, whereby when the first endplate is moved relative to the frame in a direction along the frame longitudinal axis, the first endplate is moved in a direction away from the frame to increase a height of the spacer; a second endplate configured to engage a second bone of the joint; a link moveable with respect to the frame, the link having a projection engageable with the first endplate to thereby move the first endplate along the frame longitudinal axis when the link is moved with respect to the frame; an actuating screw moveable with respect to the frame and pivotally connected to the link to cause movement of the link when the actuating screw is moved with respect to the frame; and a nut threadably engaged with the actuating screw, the nut rotatable with respect to the frame to move the actuating screw with respect to the frame.
