Abstract
A 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.
Claims21
A targeting guide, comprising:
- a body defining a first guide hole, at least one alignment hole, and a channel, wherein the first guide hole is sized and configured to receive a guide sleeve therethrough, wherein the first guide hole extends through the body on a first axis, wherein 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, wherein the at least one 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 at least one 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.

A system, comprising:
- a targeting guide, comprising:
- a body defining a first guide hole, at least one alignment hole, and a channel, wherein the first guide hole extends through the body on a first axis, and wherein 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, wherein the at least one 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 at least one 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;
- a first guide sleeve sized and configured for insertion through the first guide hole, wherein the first guide sleeve defines a channel extending therethrough.
3 more elements
A method, comprising:
- positioning a targeting guide adjacent to a first bone, wherein the targeting guide includes:
- a body defining a first guide hole, at least one alignment hole, and a channel, the first guide hole extends through the body on 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, and the at least one 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 at least one 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 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;
- inserting a first guide sleeve through the first guide hole formed in the body;
- inserting a first guide element through a channel defined by the first guide sleeve and into the first bone, wherein a portion of the tip of the targeting guide corresponds to an exit position of the first guide element from the first bone;
- removing the first guide sleeve from the first guide hole;
- and
- removing the targeting guide from adjacent to the first bone by traversing the first guide element through the channel extending from an edge of the body into an interior portion of the body.
6 more elements
A system, comprising:
- a targeting guide, comprising:
- a body defining a guide hole, a channel, and an alignment hole, wherein the guide hole extends through the body on a first axis, wherein 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, and wherein the alignment hole extends through the body on a second axis substantially parallel with the first axis;
- 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;
- and
- an alignment device selected from the group consisting of a cannulated screw, a k-wire, and a guide pin, wherein the alignment device is configured for insertion through the alignment hole,
- wherein the alignment hole is positioned on the body such that, when the alignment device is disposed within the alignment hole, the alignment device provides a visual indication of a trajectory of the first guide hole.
