Abstract

A targeting guide is disclosed includes a handle extending substantially along a longitudinal axis. The longitudinal handle defines one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough.

First claim

What is claimed is:

1. A method of forming osteotomy in a bone; comprising: inserting a burr at a surgical site;
positioning a targeting guide adjacent to an outer surface of a surgical site, wherein the targeting guide comprises a handle extending substantially along a longitudinal axis and a flat head positioned at a distal end of the handle, wherein the longitudinal handle defines at least one burr hole extending from a first side of the handle to a second side of the handle and the flat head comprises a plurality of sections each defining a plurality of guide holes that extend from a first side of the flat head to the second side, and wherein the targeting guide is slidably coupled to the burr by inserting the burr into the surgical site;
inserting one or more k-wires into at least one bone at the surgical site, wherein the one or more k-wires are inserted through any of the plurality of guide holes formed in the flat head of the targeting guide;
removing the targeting guide and the burr from the surgical site;
cutting a bone at the surgical site, wherein the cut separates the bone into a first bone portion and a second bone portion;
inserting an elevator between the first bone portion and the second bone portion at the surgical site, wherein the elevator comprises a body defining a first inner cavity sized and configured to receive at least one bone and a displacement tip extending from a distal portion of the body, the displacement tip having a predetermined radius of curvature, wherein the displacement tip is sized and configured to be inserted between the first bone portion and the second bone portion; and
forming a chevron osteotomy between the first bone portion and the second bone portion using the elevator.

2. The method of claim 1 , inserting one or more k-wires into the at least one bone comprises inserting a first k-wire through a first guide hole in the flat head and inserting a second k-wire through a second guide hole in the flat head, wherein the first guide hole is defined by a first tine extending from a base of the flat head, and wherein the second guide hole is defined by a second tine extending from the base of the flat head.

3. The method of claim 1 , wherein the bone comprises a metatarsal.

4. A method of forming a chevron osteotomy in a bone; comprising:
inserting a burr at a surgical site;
positioning a targeting guide adjacent to an outer surface of a surgical site, wherein the targeting guide comprises a handle extending substantially along a longitudinal axis, wherein the longitudinal handle defines a first positioning hole and a second positioning hole extending from a first side of the handle to a second side of the handle, and wherein the first positioning hole and the second positioning hole each extend through the handle substantially perpendicular to the longitudinal axis, wherein the first positioning hole and the second positioning hole are aligned substantially along the longitudinal axis, wherein the first positioning hole and the second positioning hole are parallel to one another;
a head coupled to a distal end of the longitudinal handle and having a distal surface comprising a stepped surface including a plurality of offset surfaces such that each of the plurality of offset surfaces defines a distal opening of at least one of the plurality of guide holes, wherein the head defines a plurality of guide holes sized and configured to receive a k-wire therethrough;
inserting one or more k-wires into at least one bone at the surgical site, wherein the one or more k-wires are inserted through one of the plurality of guide holes; and
removing the targeting guide and the burr from the surgical site;
cutting a bone at the surgical site, wherein the cut separates the bone into a first bone portion and a second bone portion;
inserting an elevator between the first bone portion and the second bone portion at the surgical site, wherein the elevator comprises a body defining a first inner cavity sized and configured to receive at least one bone and a displacement tip extending from a distal portion of the body, the displacement tip having a predetermined radius of curvature, wherein the displacement tip is sized and configured to be inserted between the first bone portion and the second bone portion; and
forming the chevron osteotomy between the first bone portion and the second bone portion using the elevator.

5. The method of claim 4 , inserting one or more k-wires into the at least one bone comprises inserting a first k-wire through a first guide hole in the head and inserting a second k-wire through a second guide hole in the head, wherein the first guide hole is defined by a first tine extending from a base of the head, and wherein the second guide hole is defined by a second tine extending from the base of the head.
