Chevron osteotomy tools and methods

A method, comprising:

• segmenting a bone into a first bone segment and a second bone segment;
• moving the first bone segment relative to the second bone segment such that the first bone segment and the second bone segment are disposed in a moved position;
• adjusting a position of a second body portion of a targeting guide relative to a first body portion of the targeting guide by moving the second body portion along a path defined by a slot defined by the first body portion of the targeting guide while the targeting guide is disposed adjacent to the bone such that the first body portion of the targeting guide is disposed adjacent to the second bone segment and the second body portion of the targeting guide abuts the second bone segment;
• locking the position of the second body portion at a location along the path defined by the slot of the first body portion using a locking mechanism of the targeting guide;
• inserting a first elongate surgical instrument into a first aperture of a plurality of apertures defined by the first body portion of the targeting guide such that the first elongate surgical instrument extends through the second bone segment and into the first bone segment;
• and
• inserting a first cannulated screw over the first elongate surgical instrument such that the first cannulated screw is disposed at least partially within the first bone segment and the second bone segment.

A system, comprising:

• a targeting guide including:
• a first body portion extending from a first end to a second end, the first end of the first body portion defining a plurality of apertures each sized and configured to receive at least one first elongate surgical instrument, the first body portion defining a slot located between the first end and the second end of the first body portion;
• a second body portion coupled to the first body portion such that the first body portion and the second body portion may move relative to one another in a path defined by the slot, the second body portion including at least one surface configured to abut a first bone portion when the targeting guide is placed adjacent to the first bone portion and a second bone portion, the second body portion defining an opening sized and configured to receive a second elongate surgical instrument;
• and
• a locking mechanism including a rotating portion, the locking mechanism configured to prevent relative movement between the first body portion and the second body portion.
