Bone cutting guide systems and methods
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.
1. A method of correcting an alignment between bones of a foot, the method comprising:
positioning a first cutting slot of a bone cutting guide over a metatarsal;
inserting a cutting member through the first cutting slot to remove a 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 cutting slot of the bone cutting guide over the cuneiform;
inserting the cutting member through the second cutting slot to remove a portion of the cuneiform; and
causing the metatarsal to fuse to the cuneiform in the moved position.
2. The method of claim 1 , wherein the bone cutting guide comprises a fixation aperture positioned distally of the first cutting slot, and further comprising inserting a fixation pin through the fixation aperture and into the metatarsal prior to inserting the cutting member through the first cutting slot.
3. The method of claim 1 , wherein the bone cutting guide comprises a fixation aperture positioned proximally of the second cutting slot, and further comprising inserting a fixation pin through the fixation aperture and into the cuneiform prior to inserting the cutting member through the second cutting slot.
4. The method of claim 1 , wherein the second cutting slot is parallel to the first cutting slot, such that inserting the cutting member through the first cutting slot and inserting the cutting member through the second cutting slot results in a cut end of the metatarsal being parallel to a cut end of the cuneiform.
5. The method of claim 1 , wherein the second cutting slot is angled relative to the first cutting slot, such that inserting the cutting member through the first cutting slot and inserting the cutting member through the second cutting slot results in a cut end of the metatarsal being angled relative to a cut end of the cuneiform.
6. The method of claim 1 , wherein the cutting member is a saw blade.
7. The method of claim 1 , wherein positioning the first cutting slot over the metatarsal comprises positioning an alignment window defined by the bone cutting guide over the joint.
8. The method of claim 1 , further comprising inserting a joint alignment blade through the bone cutting guide and into the joint to align the bone cutting guide.
9. The method of claim 1 , wherein inserting the cutting member through the first cutting slot and inserting the cutting member through the second cutting slot comprises inserting the cutting member through the first cutting slot to remove the portion of the metatarsal prior to inserting the cutting member through the second cutting slot to remove the portion of the cuneiform.
10. The method of claim 1 , wherein inserting the cutting member through the first cutting slot and inserting the cutting member through the second cutting slot comprises inserting the cutting member through the first cutting slot to remove the portion of the metatarsal after inserting the cutting member through the second cutting slot to remove the portion of the cuneiform.
11. The method of claim 1 , wherein the bone cutting guide comprises:
a first guide surface defining a first plane and a second guide surface defining a second plane, with the first cutting slot being provided between the first plane and the second plane, and
a third guide surface defining a third plane and a fourth guide surface defining a fourth plane, with the second cutting slot being provided between the third plane and the fourth plane.
12. The method of claim 1 , wherein positioning the first cutting slot over the metatarsal and positioning the second cutting slot over the cuneiform comprises positioning the bone cutting guide on a dorsal side of the metatarsal and the cuneiform.
13. The method of claim 1 , wherein causing the metatarsal to fuse to the cuneiform in the moved position comprises delivering a compound to an area between a cut end of the metatarsal and a cut end of the cuneiform.
14. 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.
15. The method of claim 14 , wherein applying the bone plate comprises applying the bone plate while the metatarsal and cuneiform are held in the moved position by the bone cutting guide.
16. The method of claim 14 , wherein the bone plate comprises a first bone plate, and further comprising applying a second bone plate across the joint.
17. The method of claim 16 , wherein applying the first bone plate comprises applying the first bone plate on a dorsal side of the metatarsal and cuneiform, and applying the second bone plate comprises applying the second bone plate on a medial side of the metatarsal and cuneiform.
18. The method of claim 1 , further comprising translating the second cutting slot perpendicularly relative to the first cutting slot to adjust a separation distance between the first cutting slot and the second cutting slot.
19. The method of claim 1 , wherein causing the metatarsal to fuse to the cuneiform in the moved position comprises compressing the metatarsal and the cuneiform together.
20. The method of claim 1 , wherein the metatarsal is a first metatarsal and the cuneiform is a first cuneiform.
