<p>An interbody spinal fusion implant (100) having an expandable height. The implant has upper and lower hinged members (102 and 106). The height is increased by an expander (122) that is located in tracks (132 and 134) between the upper and lower members (102 and 106). Rotation of the expander (122) in a plane perpendicular to the axis of the upper and lower members (102 and 106) increases the height of the implant (100).</p> |
