Abstract

Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.

First claim

Claims:

1 . A method of correcting a bunion deformity, comprising the steps of:
moving a first metatarsal from an anatomically misaligned position with respect to a second metatarsal to an anatomically aligned position with respect to the second metatarsal by applying a force to the first metatarsal, the force moving the first metatarsal to correct an alignment in more than one plane; and after moving the first metatarsal into the anatomically aligned position, preparing an end of the first metatarsal and preparing an opposing end of a medial cuneiform for fusion.

2 . The method of claim 1 , wherein the more than one plane includes any two or more of the frontal plane, transverse plane, and sagittal plane.

3 . The method of claim 1 , wherein the first metatarsal is rotated in the frontal plane.

4 . The method of claim 1 , wherein, prior to moving the first metatarsal, further including the step of mobilizing a tarsal-metatarsal joint site by releasing soft tissue or obstructing bone.

5 . The method of claim 1 , wherein the force is applied by a bone engagement member of a bone positioning device.

6 . The method of claim 1 , wherein the preparing step includes placing a tissue removing instrument in apposition to a first guide surface of a guide.

7 . The method of claim 1 , further including the step of placing the prepared end of the medial cuneiform in apposition with the prepared end of the first metatarsal.

8 . The method of claim 6 , further including the step of fixing the position of the medial cuneiform with respect to the first metatarsal by applying at least one bone fixation device across or through a joint between the apposed prepared ends of the medial cuneiform and the first metatarsal.

9 . A method of correcting a bunion deformity, comprising the steps of:
mobilizing a tarsal-metatarsal joint site by releasing soft tissue or obstructing bone; moving, with a bone positioning guide having a bone engagement member engaged with a first metatarsal and a tip contacting a metatarsal other than the first metatarsal, the first metatarsal from an anatomically misaligned position with respect to a second metatarsal to an anatomically aligned position with respect to the second metatarsal by applying a force to the first metatarsal, the force moving the first metatarsal to correct an alignment in more than one plane, including about an axis in a frontal plane; preparing an end of the first metatarsal for fusion; preparing an opposing end of a medial cuneiform for fusion; provisionally fixating a joint between the apposed prepared ends of the medial cuneiform and the first metatarsal; and fixing the position of the medial cuneiform with respect to the first metatarsal by applying at least one bone fixation device across or through the joint between the apposed prepared ends of the medial cuneiform and the first metatarsal.

10 . The method of claim 9 , wherein the end of the first metatarsal is prepared before the first metatarsal is moved into the anatomically aligned position and the end of the medial cuneiform is prepared after the first metatarsal is moved into the anatomically aligned position.

11 . The method of claim 9 , wherein the end of the first metatarsal is prepared after the first metatarsal is moved into the anatomically aligned position and the end of the medial cuneiform is prepared after the first metatarsal is moved into the anatomically aligned position.

12 . The method of claim 9 , wherein the end of the first metatarsal is prepared before the first metatarsal is moved into the anatomically aligned position and the end of the medial cuneiform is prepared before the first metatarsal is moved into the anatomically aligned position.

13 . The method of claim 9 , wherein the end of the first metatarsal is prepared after the first metatarsal is moved into the anatomically aligned position and the end of the medial cuneiform is prepared before the first metatarsal is moved into the anatomically aligned position.

14 . The method of claim 9 , further comprising, prior to moving the first metatarsal, inserting a fulcrum between the first metatarsal and the second metatarsal, wherein moving the first metatarsal from the anatomically misaligned position to the anatomically aligned position comprises rotating the first metatarsal in the frontal plane and pivoting the first metatarsal in a transverse plane about the fulcrum.

15 . A bone positioning guide, comprising:
a bone engagement member; a tip; a mechanism to urge the bone engagement member and the tip towards each other; and an actuator to actuate the mechanism, wherein actuating the mechanism causes a first bone engaged with the bone engagement member to move to correct an alignment of the first bone in more than one plane with respect to a second bone in contact with the tip, including about an axis in a frontal plane.

16 . The bone positioning guide of claim 15 , wherein the mechanism comprises a main body and a shaft movably connected to the main body proximate a first end of the main body;
wherein 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.

17 . The bone positioning guide of claim 15 , wherein the tip includes a textured surface.

18 . The bone positioning guide of claim 15 , wherein the tip is tapered.

19 . The bone positioning guide of claim 16 , wherein the actuator is a knob coupled to the shaft.

20 . A bone preparation guide, comprising:
a body with a first guide surface to define a first preparing plane and a second guide surface to define a second preparing plane, the first and second guide surfaces being spaced from each other by a distance, and an opening disposed between the first and second guide surfaces; and a first end extending from the body in a first direction and a second end extending from the body in a second direction, the second direction being different than the first direction, each of the first end and the second end including a fixation aperture configured to receive a fixation pin.
