Abstract:
1. A spinal device comprising: an upper plate member having a proximal end and a distal end; a lower plate member having a proximal end and a distal end, the lower plate member connected to the upper plate member, wherein the lower plate member comprises a lower surface configured to contact a vertebral body and an upper surface opposed to the lower surface, wherein the opposed upper surface includes one or more grooves; and an anterior plate member rotatably and linkably connected to the upper plate member, wherein the anterior plate member is configured to engage the one or more grooves on the lower plate, wherein the anterior plate member comprises a first end and a second end, wherein the first end is connected to the distal end of the upper plate member and the second end is a free end that engages the one or more grooves on the lower plate member, wherein when in an expanded state, the free end of the anterior plate member moves outwardly toward the distal end of the lower plate member creating a vertical force that displaces the upper and lower plate members away from each other, wherein the one or more grooves are positioned closer to the distal end of the lower plate member than the proximal end of the lower plate member, and wherein the anterior plate member engages the one or more grooves closer to the distal end of the lower plate member than the proximal end of the lower plate member while displacing the upper and lower plate members away from each other.
