13. 13 . The system of claim 7 , wherein the alignment arm defines an arc extending from the first end to the second end.
14. 14 . A method, comprising: providing a targeting guide having a body defining a first guide hole, an alignment hole, and a channel, where the first guide hole is sized and configured to receive a guide sleeve and extends through the body along a first axis, the channel extends from an edge of the body into an interior portion of the body such that the channel intersects the first guide hole so that the alignment hole is oriented parallel to the first guide hole and is positioned on the body such that, when an alignment device is disposed within the alignment hole, the alignment device provides a visual indication of a trajectory of the first guide hole; an alignment arm extending between a first end and a second end, wherein the first end is coupled to the body; and a tip extending from the second end of the alignment arm, wherein the tip is aligned with the first axis of the first guide hole; positioning a targeting guide adjacent to a first bone; inserting a first guide sleeve through the first guide hole so that the first guide sleeve defines a first channel; inserting a first guide element through the channel of the first guide sleeve and into the first bone such that a portion of the tip of the targeting guide corresponds to an exit position of the first guide element from the first bone.
15. 15 . The method of claim 14 , comprising inserting a first screw into the first bone, wherein the first screw is inserted over the first guide element.
16. 16 . The method of claim 15 , wherein the free end of the tip of the targeting guide corresponds the exit position of the first guide element from a first bone.
17. 17 . The method of claim 14 , comprising: inserting a second guide sleeve through a second guide hole formed in the body, wherein the second guide sleeve defines a second channel, and wherein the second channel is substantially parallel with the first channel of the first guide sleeve after insertion of the first guide sleeve and the second guide sleeve into respective first guide hole and second guide hole; and inserting a second guide element through the channel of the second guide sleeve and into the first bone.
18. 18 . The method of claim 17 , comprising aligning a first alignment feature and a second alignment feature of the targeting guide on a predetermined axis prior to insertion of the first sleeve into the first guide hole.
19. 19 . A system, comprising: a targeting guide including: a first portion extending between a first end and a second end; a second portion extending between a third end and a fourth end, the second portion movably coupled to the first portion, the second portion defining at least one guide hole adjacent to the fourth end and a channel that inwardly extends from the fourth end and intersects the at least one guide hole; and an arm coupled to and extending from the first portion of the body, the arm terminating at a tip having a predetermined positional relationship with an axis defined by the at least one guide hole, wherein the portion has an arcuate shape such that a relative position between the tip and the axis defined by the at least one guide hole is maintain when the second portion moves relative to the first portion.
20. 20 . The system of claim 19 , wherein the at least one guide hole includes a pair of spaced apart guide holes.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 16/500,501, which is a National Stage Application, filed under 35 U.S. C. 371, of International Patent Application No. PCT/US2018/044030, filed on Jul. 27, 2018 which claims benefit of U.S. Provisional Application Ser. No. 62/541,410, filed on Aug. 4, 2017, entitled “SCREW TARGETING GUIDE SYSTEM AND METHOD,” the entire contents of which are incorporated herein by reference. BACKGROUND During surgery, such as foot surgery, it may be necessary to fix a position of a first bone fragment and a second bone fragment. For example, in some instances, an osteotomy is formed in a bone to correct one or more defects. After forming the osteotomy, a first fragment of the bone and a second fragment of a bone are positioned to correct the defect and are fixed in place using one or more fixation elements. In other embodiments, one or more bone fragments are formed as a result of an injury and/or medical procedure. Current systems rely on the placement of guide elements prior to insertion of the fixation elements. Placement of the guide elements is performed by a surgeon and often requires the surgeon to insert and remove the guide element several times before a desired placement is achieved. The repeated insertion and removal of guide elements results in additional wounds in a patient and increase pain, recovery time, and complexity of surgery (including difficulty, increased surgical time, etc.) SUMMARY In various embodiments, a targeting guide is disclosed. The targeting guide includes a body defining a first guide hole sized and configured to receive a guide sleeve therethrough. The first guide hole extends through the body on a first axis. An alignment arm extends between a first end and a second end. The first end is coupled to the body. A tip extends from the second end of the alignment arm. A free end of the tip is aligned with the first axis of the first guide hole. In various embodiments, a system is disclosed. The system includes a targeting guide having a body defining a first guide hole. The first guide hole extends through the body on a first axis. An alignment arm extends between a first end and a second end. The first end is coupled to the body. A tip extends from the second end of the alignment arm. A free end of the tip is aligned with the first axis of the first guide hole. A first sleeve sized and configured for insertion through the first guide hole. The first sleeve defines a channel extending therethrough. In various embodiments, a method is disclosed. The method includes positioning a targeting guide adjacent to a first bone. The targeting guide includes a body, an alignment arm extending between a first end coupled to the body and a second end, and a tip extending from the second end of the alignment arm and having a free end. A first sleeve is inserted through a first guide hole formed in the body. The first sleeve defines a first channel extending therethrough. A first guide element is inserted through the channel of the first sleeve and into the first bone. A portion of the tip of the targeting guide corresponds to an exit position of the first guide element from the first bone.
