Targeting guide assembly

1. A targeting guide assembly, comprising:

a first bracket;

a second bracket rotatable relative to said first bracket;

a cannula guide body movable along a curvilinear path within a slot formed in said first bracket, wherein the slot extends between a first arm and a second arm of the first bracket, the slot including a track formed in the first arm, and the track is configured to guide movement of the cannula guide body along the curvilinear path;

a cannula received within a bore of said cannula guide body; and

a cannula sleeve received within said cannula.

2. The assembly as recited in claim 1 , comprising a knob that rotatably connects said second bracket to said first bracket.

3. The assembly as recited in claim 1 , wherein said cannula guide body includes a boss that extends into said track.

4. The assembly as recited in claim 1 , comprising a knob mounted to said cannula guide body, said knob protruding outwardly from said slot.

5. The assembly as recited in claim 1 , comprising a guidewire received through said cannula sleeve.

6. The assembly as recited in claim 1 , comprising a ratchet received within a recessed opening of said cannula guide body.

7. The assembly as recited in claim 6 , wherein said ratchet includes a first engagement feature adapted to engage a second engagement feature of a cannula received within said cannula guide body.

8. The assembly as recited in claim 7 , wherein one of said first engagement feature and said second engagement feature is a recess and the other of said first engagement feature and said second engagement feature is a tooth.

9. The assembly as recited in claim 1 , comprising an indicator probe received through a bore of said second bracket.

10. The assembly as recited in claim 9 , comprising a knob configured to lock a positioning of said indicator probe within said bore.

11. The assembly as recited in claim 1 , wherein said cannula is axially between said first arm and said second arm of said first bracket.

12. The assembly as recited in claim 1 , wherein said track extends completely through said first arm, and comprising a second track formed in said second arm without extending completely through said second arm.

13. The assembly as recited in claim 1 , wherein said cannula sleeve includes a first opening having a first diameter that is smaller than a second diameter of a second opening of said cannula.

14. The assembly as recited in claim 1 , wherein said cannula sleeve includes a plurality of openings, and each of said plurality of openings is sized to receive a guidewire.

15. A surgical method, comprising:

positioning an indicator probe of a targeting guide assembly at a first location of a joint, wherein the indicator probe is inserted through a first bore of the targeting guide assembly;

positioning a cannula of the targeting guide assembly at a second location relative to the joint such that the cannula is aligned to establish a desired trajectory toward the indicator probe, wherein positioning the cannula includes inserting the cannula through a second bore of a cannula guide body and then moving the cannula guide body along a curvilinear path established by a slot of the targeting guide assembly,

wherein, once received within the second bore, the cannula extends through the slot at a location that is axially between a first arm and a second arm of a first bracket of the targeting guide assembly; and

inserting a surgical instrument through the cannula along the desired trajectory.

16. The method as recited in claim 15 , wherein moving the cannula guide body includes sliding the cannula guide body along the curvilinear path.

17. The method as recited in claim 15 , wherein positioning the indicator probe includes moving a second bracket of the targeting guide assembly relative to the first bracket.

18. The method as recited in claim 15 , wherein positioning the cannula includes ratcheting the cannula up or down relative to the cannula guide body.

19. The method as recited in claim 15 , wherein the surgical instrument is a guidewire and the inserting includes moving the guidewire along the desired trajectory until it contacts a tip of the indicator probe.

20. The method as recited in claim 15 , wherein the surgical instrument is a guidewire and the method further comprises:

removing the targeting guide assembly from the joint while leaving the guidewire in place within the joint; and

drilling over the guidewire with a cannulated drill bit.

21. A targeting guide assembly, comprising:

a first bracket including a first curved body;

a second bracket including a second curved body;

a knob rotationally connecting the first bracket and the second bracket, wherein the knob is configured to twist in a first direction to lock the second bracket relative to the first bracket and in a second direction to enable the second bracket to rotate relative to the first bracket;

a cannula guide body mounted within a slot of the first bracket, wherein the cannula guide body is movable along a curvilinear path established by the slot;

a cannula received through a first bore of the cannula guide body;

a cannula sleeve received within the cannula;

a guidewire received through the cannula sleeve; and

an indicator probe received through a second bore of the second bracket.
