Claims
- 1. A device for angle adjustment during an osteotomy of a bone, the device comprising:
a plurality of pins for engaging the bone a support structure having a first portion and a second portion wherein
the first portion and the second portion are pivotally attached such that pivoting may occur in only one plane wherein the first portion is attached by a pin to the bone and the second portion is attached by a pin to the bone; and an angle measurer positioned between the first and the second portions to provide a relative angle between the first and second portions.
- 2. A device according to claim 1, wherein the angle measurer is a goniometer.
- 3. A device according to claim 1, further comprising:
a locking mechanism for restraining the first and second portions from pivoting.
- 4. A device according to claim 3 wherein the locking mechanism includes a protrusion from the angle measurer and a pin that passes through the protrusion.
- 5. A device according to claim 1, wherein the first portion is attached at a point above a point where the bone is to be separated and wherein the second portion is attached at a point below where the bone is to be separated.
- 6. A device according to claim 1, wherein the angle measurer has a void through which a tunnel can be drilled in the bone.
- 7. A device according to claim 6, wherein the void is sized to receive a drill and provides alignment for guiding the drill.
- 8. A device according to claim 6, wherein the void is cylindrical in shape.
- 9. A device according to claim 6, wherein the void is configured to receive a plurality of drilling shapes.
- 10. A device according to claim 9, wherein the plurality of drilling shapes each have different diameters.
- 11. A device according to claim 10, wherein the void has an outer diameter for an oblong shape and an inner diameter for a circular shape.
- 12. A support for aligning bone pieces comprising: a first end to which one bone piece is coupled, a second end to which another bone piece is coupled, a point of pivot between the first and second ends to move the bone pieces into alignment, and a device positioned at the point of pivot to determine the angle of alignment.
- 13. A support according to 12, wherein the support includes a frame having two opposing members connected to one another at each of the first and second ends.
- 14. A support according to claim 12, wherein the device is a goniometer.
