Abstract

A bone cutting guide may include a support that contains a shaft movable relative to the support. The shaft may carry a guide member having one or more cut guides through which a clinician inserts a cutting member to cut bone positioned under the guide cut guides. In operation, a clinician may fixate the support of the bone cutting guide to a bone and translate the guide member until the one or more cut guides are positioned at a desired cut location. The clinician may then perform a cut through the cut guide. In some examples, the bone cutting guide includes additional components, such as bridging member or secondary cut guide, to provide additional functionality.

First claim

The invention claimed is:

1. A bunion correction method comprising:
positioning a first bone cutting guide slot over a portion of a metatarsal to be cut;
attaching the first bone cutting guide slot to the metatarsal with a first fixation pin inserted into the metatarsal and a second fixation pin inserted into the metatarsal, the first fixation pin and the second fixation pin being positioned distally of the first bone cutting guide slot;
inserting a cutting member through the first bone cutting guide slot to cut the portion of the metatarsal;
adjusting an alignment of the metatarsal relative to a cuneiform separated from the metatarsal by a joint to establish a moved position of the metatarsal;
positioning a second bone cutting guide slot over a portion of the cuneiform to be cut, the second bone cutting guide slot being attached to the metatarsal by at least the first fixation pin inserted into the metatarsal and the second fixation pin inserted into the metatarsal, the first fixation pin and the second fixation pin being positioned distally of the second bone cutting guide slot;
inserting the cutting member through the second cutting slot to cut the portion of the cuneiform; and
causing the metatarsal to fuse to the cuneiform in the moved position.

2. The method of claim 1 , further comprising, after adjusting the alignment of the metatarsal relative to the cuneiform to establish the moved position of the metatarsal, lifting the first bone cutting guide slot off the first fixation pin and the second fixation pin.

3. The method of claim 1 , wherein:
inserting the cutting member through the first bone cutting guide slot to cut the portion of the metatarsal comprises inserting the cutting member through the first bone cutting guide slot to cut the portion of the metatarsal without the second bone cutting guide slot being positioned over the portion of the cuneiform to be cut; and
inserting the cutting member through the second bone cutting guide slot to cut the portion of the cuneiform comprises inserting the cutting member through the second bone cutting guide slot to cut the portion of the cuneiform without the first bone cutting guide slot being positioned over the portion of the metatarsal to be cut and configured to receive the cutting instrument therethrough.

4. The method of claim 1 , wherein positioning the first bone cutting guide slot over the portion of the metatarsal to be cut comprises positioning a support extending perpendicularly from the first bone cutting guide slot over a dorsal surface of the metatarsal with the support extending substantially parallel to a longitudinal axis of the metatarsal.

5. The method of claim 4 , wherein attaching the bone cutting guide slot to the metatarsal with the first fixation pin inserted into the metatarsal and the second fixation pin inserted into the metatarsal comprises inserting the first fixation pin through a first fixation aperture of the support into the metatarsal and inserting the second fixation pin through a second fixation aperture of the support into the metatarsal.

6. The method of claim 1 , wherein positioning the second bone cutting guide slot over the portion of the cuneiform to be cut comprises positioning a support extending perpendicularly from the second bone cutting guide slot over a dorsal surface of the metatarsal with the support extending substantially parallel to a longitudinal axis of the metatarsal.

7. The method of claim 6 , wherein, when the second bone cutting guide slot is positioned over the portion of the cuneiform to be cut, the first fixation pin extends from the metatarsal through a first fixation aperture of the support and the second fixation pin extends from the metatarsal through a second fixation aperture of the support.

8. The method of claim 1 , wherein attaching the first bone cutting guide slot to the metatarsal with the first fixation pin and the second fixation pin comprises:
inserting the first fixation pin extending substantially perpendicular to a dorsal surface of the metatarsal; and
inserting the second fixation pin extending substantially perpendicular to the dorsal surface of the metatarsal with the second fixation pin being substantially parallel to the first fixation pin.

9. The method of claim 1 , further comprising, after positioning the second bone cutting guide slot over the portion of the cuneiform to be cut, attaching the second bone cutting guide slot to the cuneiform with a third fixation pin inserted into the cuneiform.

10. The method of claim 1 , wherein the first bone cutting guide slot and the second bone cutting guide slot are configured to result in a cut end of the metatarsal being substantially parallel to a cut end of the cuneiform.

11. The method of claim 1 , wherein the first bone cutting guide slot and the second bone cutting guide slot are configured to result in a cut end of the metatarsal being angled relative to a cut end of the cuneiform.

12. The method of claim 1 , wherein the cutting member is a saw blade.

13. The method of claim 1 , wherein inserting the cutting member through the first bone cutting guide slot and inserting the cutting member through the second bone cutting guide slot comprises inserting the cutting member through the first bone cutting guide slot to cut the portion of the metatarsal prior to inserting the cutting member through the bone cutting guide slot to cut the portion of the cuneiform.

14. The method of claim 1 , wherein inserting the cutting member through the bone cutting guide slot and inserting the cutting member through the second bone cutting guide slot comprises inserting the cutting member through the first bone cutting guide slot to cut the portion of the metatarsal after inserting the cutting member through the second bone cutting guide slot to cut the portion of the cuneiform.

15. The method of claim 1 , wherein:
the first bone cutting guide slot is provided between a first guide surface defining a first plane and a second guide surface defining a second plane; and
the second bone cutting guide slot is provided between a third guide surface defining a third plane and a fourth guide surface defining a fourth plane.

16. The method of claim 1 , comprising:
a first guide defining the first bone cutting guide slot; and
a second guide defining the second bone cutting guide slot.

17. The method of claim 1 , wherein causing the metatarsal to fuse to the cuneiform in the moved position comprises applying a bone plate across the joint.

18. The method of claim 1 , further comprising compressing the metatarsal and the cuneiform together.

19. The method of claim 1 , wherein the metatarsal is a first metatarsal and the cuneiform is a first cuneiform.

20. A bunion correction method comprising:
positioning a first bone cutting guide slot defined by a first guide over a portion of a metatarsal to be cut;
attaching the first guide to a dorsal surface of the metatarsal by inserting a first fixation pin through a first fixation aperture connected to the first guide and inserting a second fixation pin through a second fixation aperture connected to the first guide, wherein the first fixation aperture is offset along a length of the metatarsal from the second fixation aperture, and inserting the first fixation pin and inserting the second fixation pin comprises inserting the first fixation pin and inserting the second fixation pin extending substantially parallel to each other;
inserting a saw blade through the first bone cutting guide slot to cut the porti
