Abstract

A bone cut guide includes a stem having a stem longitudinal axis and an anchoring portion proximal to the stem and connected to the stem by a cut body. The anchoring portion includes an anchoring opening configured to receive a wire therethrough to connect the anchoring portion to a bone. The cut body includes a cut slot configured to receive a saw to cut the bone.

First claim

We claim:

1. A method for use in aligning bones of a foot, comprising:
attaching a first portion of a bone cut guide to a first bone by receiving a first wire in a first opening of the first portion of the bone cut guide;
locating the bone cut guide in a first position relative to the first bone and a second bone and making a first cut of the first bone using a slot of the bone cut guide;
locating the bone cut guide in a second position relative to the first bone and the second bone and making a second cut of the first bone or the second bone; and
aligning the first bone with the second bone in a desired final position;
wherein the bone cut guide comprises a stem having a stem longitudinal axis, the method further comprising attaching the stem to the second bone by receiving a second wire in a stem anchoring opening of the stem and inserting the second wire in the second bone;
wherein the first portion comprises an anchoring portion having an anchoring portion longitudinal axis, the stem comprises a stem longitudinal axis, the bone cut guide comprises a cut body, and the anchoring portion longitudinal axis is aligned with the stem longitudinal axis, the anchoring portion and the stem connected to the cut body located therebetween, the cut body comprising the slot; and
wherein the stem comprises an elongated portion and a distal portion located distal to the elongated portion, the distal portion projecting upwardly and downwardly from the elongated portion.

2. The method of claim 1 wherein said stem longitudinal axis is offset transversely relative to a central axis perpendicular to a slot longitudinal dimension of said slot located at a transverse center of said slot longitudinal dimension.

3. The method of claim 1 wherein said stem longitudinal axis is aligned with a central axis perpendicular to a body longitudinal dimension of said cut body located at a transverse center of said body longitudinal dimension.

4. The method of claim 1 wherein the slot has a slot longitudinal axis aligned about perpendicularly to a longitudinal axis of the bone cut guide.

5. The method of claim 1 wherein the making the second cut comprises making the second cut in a second slot of the bone cut guide, the second slot having a second slot longitudinal axis aligned about parallel to the slot and located distal to the slot.

6. The method of claim 1 further comprising receiving a second wire in a second opening of the anchoring portion to connect the anchoring portion to the first bone to inhibit a rotation of the anchoring portion about the first wire.

7. The method of claim 1 wherein the making the second cut comprises making the second cut in the slot.

8. The method of claim 1 wherein the making the second cut comprises making the second cut in a second slot of the cut body, the second slot distal to the first slot.
