Abstract

A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

First claim

The invention claimed is:

1. A method of positioning a bone comprising:
engaging a surface of a bone engagement member of a bone positioning guide with a first bone;
placing a tip of the bone positioning guide in contact with a second bone, the second bone being different from the first bone; and
moving the bone engagement member with respect to the tip to change the position of the first bone with respect to the second bone, wherein moving the bone engagement member comprises correcting an alignment of the first bone in more than one plane with respect to the second bone, including about an axis in a frontal plane.

2. The method of claim 1 , wherein the first bone is a first metatarsal and the second bone is a second metatarsal.

3. The method of claim 2 , wherein engaging the surface of the bone engagement member of the bone positioning guide with a first bone comprises placing the surface of the bone engagement member in contact with a medial ridge of the first metatarsal.

4. The method of claim 2 , wherein placing the tip of the bone positioning guide in contact with the second bone comprises placing the tip of the bone positioning guide in contact with a lateral side of the second metatarsal.

5. The method of claim 1 , wherein the bone engagement member is laterally offset from the tip.

6. The method of claim 1 , further comprising adjusting a radial position of the first bone with respect to the surface of the bone engagement member.

7. The method of claim 1 , wherein moving the bone engagement member with respect to the tip comprises moving a shaft to which the bone engagement member is rotatably coupled toward the tip.

8. The method of claim 7 , wherein moving the shaft comprises rotating an actuator coupled to the shaft.

9. The method of claim 1 , wherein
the bone positioning guide comprises a main body and a shaft movably connected to the main body proximate a first end of the main body;
the bone engagement member is rotatably coupled to the shaft; and
the tip is at a second end of the main body opposite the first end.

10. The method of claim 9 , wherein the main body has a first bend of approximately 90 degrees, a second bend of approximately 90 degrees, and a linear body portion separating the first bend and the second bend, such that the first end and the second end are parallel to each other and offset by the linear body portion.

11. The method of claim 1 , wherein
the bone positioning guide further comprises a main body member and a shaft movably connected to the main body member proximate a first end of the main body,
the bone engagement member is rotatably coupled to the shaft, and
the tip is at a second end of the main body opposite the first end.

12. The method of claim 11 , wherein the tip includes serrations.

13. The method of claim 11 , wherein the tip is tapered.

14. The method of claim 11 , wherein the bone positioning guide further includes a knob coupled to the shaft and the shaft is threaded.

15. The method of claim 11 , wherein the shaft includes a cannulation.

16. The method of claim 11 , wherein the surface is concave.

17. The method of claim 11 , wherein the tip is curved.
