A bodiless bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bodiless bone fusion device comprises one or more extendable plates, one or more extending blocks in communication with the extendable plates, one or more positioning elements for adjusting the extendable plates by manipulating the extending blocks, and one or more support panels for holding the positioning elements and guiding the extendable plates. The plates are able to be advantageously positioned in the confined space between the vertebrae to help brace the device until the bone has fused.

1. A bodiless bone fusion device for insertion into a desired location comprising: an extending mechanism including a plurality of extending blocks all mechanically coupled with a single body of a positioning element such that rotation of the positioning element causes the plurality of extending blocks to move with respect to the positioning element;a first plate having a first body:a second plate having a second body separate and distinct from the first body, the first and second plates straddling the extending mechanism and mechanically coupled with the plurality of extending blocks such that when the plurality of extending blocks move with respect to the positioning element, the plates move along a path with respect to each other between a retracted position in which the plates are adjacent to each other to an extended position in which the plates are spread apart from and do not directly contact each other, wherein the plates are sized such that at least a portion of a perimeter of the plates about the path align with an outermost perimeter of the device about the path, wherein the extending blocks move away from each other to opposite ends of the single body of the positioning element when causing the plates to move to the extended position, and further wherein the extending blocks directly contact and support opposite ends of both of the plates when in the extended position; andone or more biasing elements physically coupled with the first plate and the second plate and positioned such that in the extended position the biasing elements extend from the first plate to the second plate through a gap between the first plate and the second plate, and further wherein the one or more biasing elements apply a force resisting the movement of the plates from the retracted position to the extended position. 2. The device of claim 1, wherein the plates are sized such that the entirety of the perimeter of the plates about the path align with the outermost perimeter of the device about the path. 3. The device of claim 1, wherein the one or more biasing elements have a shape selected from the group consisting of a ring, a C-shape and a ring-shaped coil. 4. The device of claim 1, further comprising a plurality of support panels coupled with the extending mechanism, wherein at least one of the support panels comprises a pair of grip tabs that protrude from sides of the support panel into a pair of grip apertures formed by the plates when the plates are in the retracted position. 5. A bodiless bone fusion device for insertion into a desired location comprising: an extending mechanism including a plurality of extending blocks mechanically coupled with a positioning element such that rotation of the positioning element causes the plurality of extending blocks to move with respect to the positioning element;a first plate having a first body;a second plate having a second body separate and distinct from the first body, the first and second plates straddling the extending mechanism and mechanically coupled with the plurality of extending blocks such that when the plurality of extending blocks move with respect to the positioning element, the plates move along a path with respect to each other between a retracted position in which the plates are in direct contact with each other to an extended position in which the plates are spread apart from and do not directly contact each other, wherein the plates are sized such that at least a portion of a perimeter of the plates about the path align with an outermost perimeter of the device about the path; andone or more biasing elements physically coupled with the first plate and the second plate and positioned such that in the extended position the biasing elements extend from the first plate to the second plate through a gap between the first plate and the second plate, and further wherein the one or more biasing elements apply a force resisting the movement of the plates from the retracted position to the extended position. 6. The device of claim 5, wherein the plates are sized such that the entirety of the perimeter of the plates about the path align with the outermost perimeter of the device about the path. 7. The device of claim 5, wherein the one or more biasing elements have a shape selected from the group consisting of a ring, a C-shape and a ring-shaped coil. 8. The device of claim 5, further comprising a plurality of support panels coupled with the extending mechanism, wherein at least one of the support panels comprises a pair of grip tabs that protrude from sides of the support panel into a pair of grip apertures formed by the plates when the plates are in the retracted position. 9. A bodiless bone fusion device for insertion into a desired location comprising: an extending mechanism including a plurality of extending blocks mechanically coupled with a single body of a positioning element such that rotation of the positioning element causes the plurality of extending blocks to move with respect to the positioning element;a first plate having a first body;a second plate having a second body separate and distinct from the first body, the first and second plates straddling the extending mechanism and mechanically coupled with the plurality of extending blocks such that when the plurality of extending blocks move with respect to the positioning element, the plates move along a path with respect to each other between a retracted position in which the plates are in contact with each other to an extended position in which the plates are spread apart from and do not directly contact each other, wherein the plates are sized such that at least a portion of a perimeter of the plates about the path align with an outermost perimeter of the device about the path;one or more biasing elements physically coupled with both of the plates and positioned such that in the extended position the biasing elements extend from the first plate to the second plate through a gap outside the plates, and further wherein the one or more biasing elements apply a force resisting the movement of the plates from the retracted position to the extended position; anda plurality of support panels coupled to opposite sides of the single body of the extending mechanism, wherein at least one of the support panels comprises a pair of grip tabs that protrude from sides of the support panel into a pair of grip apertures formed by the plates when the plates are in the retracted position. 10. The device of claim 9, wherein the plates are sized such that the entirety of the perimeter of the plates about the path align with the outermost perimeter of the device about the path. 11. The device of claim 9, wherein the one or more biasing elements have a shape selected from the group consisting of a ring, a C-shape and a ring-shaped coil.
