Alignment devices and methods

1. A system for guiding alignment of fixation devices,

comprising:

a first alignment guide including a first retention mechanism adapted to couple the first alignment guide to a first fixation device on a first side of a cut body part, and a protrusion having a conical shape that extends from a first face of the first alignment guide; and

a second alignment guide including a second retention mechanism adapted to couple the second alignment guide to a second fixation device on a second side of the cut body part, and an alignment aperture in a second face of the second alignment guide adapted to receive the protrusion, wherein the first and second alignment guides assist in aligning the first fixation device with the second fixation device to close the cut body part.

2. The system of claim 1 , wherein the first alignment guide includes an aperture extending substantially vertically through the first alignment guide and adapted to align with a ratchet mechanism of the first fixation device.

3. The system of claim 1 , wherein the second alignment guide includes an aperture extending substantially vertically through the second alignment guide and adapted to align with a fastener of the second fixation device.

4. The system of claim 1 , wherein the first retention mechanism includes:

a pivot member pivotably coupled to a body of the first alignment guide;

a bias member adapted to bias the pivot member to a closed position; and

an engagement member adapted to engage the first fixation device when the pivot member is in the closed position.

5. The system of claim 1 , wherein

the protrusion includes first and second protrusions extending from-the first face of the first alignment guide; and

the alignment aperture includes first and second alignment apertures in the second face of the second alignment guide adapted to respectively receive the first and second protrusions.

6. The system of claim 1 , wherein the conical shape has a cross sectional area that decreases as the protrusion extends away from the first face.

7. The system of claim 1 , wherein the second retention mechanism includes:

a pivot member pivotably coupled to a body of the second alignment guide;

a bias member adapted to bias the pivot member to a closed position; and

an engagement member adapted to engage the second fixation device when the pivot member is in the closed position.

8. A device for guiding alignment of a fixation device, comprising:

a body portion;

a protrusion having a conical shape that extends from a face of the body portion, and that is adapted to engage an aperture of second device; and

a retention mechanism including a pivot member pivotably coupled to the body portion and having an engagement member adapted to engage a first fixation device when the pivot member is in a closed position, and couple the device to the first fixation device on a first side of a cut body part.

9. The device of claim 8 , further comprising an aperture extending substantially vertically through the body portion.

10. The device of claim 8 , further comprising a bias member disposed in the body portion and adapted to bias the pivot member to the closed position.

11. The device of claim 8 , wherein the protrusion includes first and second protrusions.

12. A device for guiding and aligning two pieces of a fixation device, comprising:

a first guide having a first pair of gripping elements movably coupled to the first guide and adapted to be movable between a first open position and a first closed position, in the first closed position, the first pair of gripping elements being adapted to releasably hold a first piece of the fixation device, wherein the first guide includes a protrusion having a conical shape that extends from a first face of the first guide; and

a second guide having a second pair of gripping elements movably coupled to the second guide and adapted to be movable between a second open position and a second closed position, in the second closed position, the second pair of gripping elements being adapted to releasably hold a second piece of the fixation device, the first and second guides are adapted to interconnect with one another to bring the first and second pieces of the fixation device into alignment.

13. The device of claim 12 , wherein the protrusion includes first and second protrusions extending from the first face of the first guide.

14. The device of claim 12 , wherein the conical shape has a cross sectional area that decreases as the protrusion extends away from the first face.

15. The device of claim 12 , wherein the first pair of gripping elements includes:

a first pivot member pivotably coupled to a first end of the first guide and having a first engagement member adapted to hold the first piece; and

a second pivot member pivotably coupled to a second end of the first guide and having a second engagement member adapted to hold the first piece.

16. The device of claim 12 , wherein the second guide includes an aperture in a second face of the second guide adapted to receive the protrusion to interconnect the first and second guides and bring the first and second pieces of the fixation device into alignment.

17. The device of claim 16 , wherein the second pair of gripping elements includes:

a first pivot member pivotably coupled to a first end of the second guide and having a first engagement member adapted to hold the second piece; and

a second pivot member pivotably coupled to a second end of the second guide and having a second engagement member adapted to hold the second piece.

18. The device of claim 12 , wherein the first guide includes a first recess adapted to receive the first piece of the fixation device, and the second guide includes a second recess adapted to receive the second piece of the fixation device.
