Chevron osteotomy tools and methods
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.
1. A targeting guide, comprising:
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 defines a first hole axis and the second positioning hole defines a second hole axis, and wherein the first hole axis and the second hole axis are parallel to one another; and
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, wherein the head defines a plurality of guide holes sized and configured to receive a k-wire therethrough.
2. The targeting guide of claim 1 , wherein each of the plurality of offset surfaces defines a distal opening of at least one of the plurality of guide holes.
3. The targeting guide of claim 1 , wherein a first set of the plurality of guide holes extends through the head at a first angle and a second set of the plurality of guide holes extend through the head at a second angle.
4. The targeting guide of claim 1 , wherein the first positioning hole and the second positioning hole each extend through a proximal portion of the handle.
5. The targeting guide of claim 1 , wherein the head defines a cutout extending from a distal surface towards a proximal surface of the head, wherein the cutout is sized and configured to receive a bone therein.
6. The targeting guide of claim 1 , wherein the head comprises a first tine, a second tine, and a third tine, wherein the first tine is separated from the second tine by a first channel and the second tine is separated from the third tine by a second channel.
7. The targeting guide of claim 6 , wherein each of the first, second, and third tine define at least one of the plurality of guide holes.
8. The targeting guide of claim 6 , comprising a rectangular anchoring section extending from a distal end of the second tine.
9. The targeting guide of claim 1 , comprising a rotatable joint, wherein the rotatable joint couples the handle to the head, and wherein the head is rotatable with respect to the handle.
10. The targeting guide of claim 1 , wherein a distal surface of the head defines a cutout extending from a distal end of the head towards an interior portion of the head, the cutout being disposed between a first stepped portion and a second stepped portion of the head.
11. The targeting guide of claim 10 , wherein the cutout forms an opening that faces the distal end of the head.
12. The targeting guide of claim 10 , wherein:
each of the first stepped portion and the second stepped portion defines at least one of the plurality of guide holes having a third hole axis and fourth hole axis, respectively, and
the first hole axis of the first stepped portion and the second hole axis of the second stepped portion are parallel to one another.
13. The targeting guide of claim 1 , wherein:
the handle further comprises a gripping portion disposed on a third side of the handle adjacent to the first side of the handle, and
the gripping portion comprises a grooved surface extending from the first side of the handle to a second side of the handle and being disposed between the first positioning hole and the second positioning hole.
