engaging an indexing member of a tunnel guide with the dorsal surface of the metapodial bone;

aligning an alignment feature parallel to the metapodial bone axis; and

directing a guide member axis on a line from a medial to a lateral epicondyle of the metapodial bone.

11. The method of claim 9 further comprising forming a second bone tunnel extending from the medial side of the metapodial bone to the lateral side of the metapodial bone and plantar to the first bone tunnel.

12. The method of claim 11 wherein forming the second bone tunnel comprises:

engaging an indexing member of a tunnel guide with the dorsal surface of the metapodial bone;

aligning an alignment feature parallel to the metapodial bone axis; and

directing a guide member axis on a line parallel and plantar to a line from a medial to a lateral epicondyle of the metapodial bone.

13. The method of claim 6 wherein forming a phalangeal bone tunnel comprises: forming a dorsal-plantar bone tunnel through the proximal phalanx near the joint.

14. The method of claim 6 wherein forming the metapodial bone tunnel comprises:

positioning the cutting guide adjacent the joint;

engaging a first reference portion of the cutting guide with a first anatomic landmark;

aligning a first guiding portion of the cutting guide in alignment with a medial-dorsal aspect of the metapodial bone;

aligning a second guiding portion of the cutting guide in alignment with a lateral-dorsal aspect of the metapodial bone;

guiding the cutter with the first guiding portion to form a first tunnel into the metapodial bone; and

guiding the cutter with the second guiding portion to form a second tunnel into the metapodial bone intersecting the first tunnel.

15. The method of claim 14 wherein engaging a reference portion with a first anatomic landmark comprises engaging a surface of the reference portion with an articular surface of the metapodial phalangeal joint.

16. The method of claim 15 wherein the surface is a concave surface and it is engaged with the head of the metapodial bone.

17. The method of claim 15 wherein the surface is a convex surface and it is engaged with the head of the proximal phalanx bone.

18. The method of claim 14 wherein the guide further comprises an alignment axis, the method further comprising: aligning the alignment axis parallel to the longitudinal axis of the metapodial bone.

19. The method of claim 6 wherein forming the phalangeal bone tunnel comprises:

positioning the cutting guide adjacent the joint;

engaging a first reference portion of the cutting guide with a first anatomic landmark;

aligning a guiding portion of the cutting guide in alignment with the proximal phalanx; and

guiding a cutter with the guiding portion to form the phalangeal tunnel.

20. The method of claim 19 wherein engaging a reference portion with a first anatomic landmark comprises engaging a surface of the reference portion with an articular surface of the metapodial phalangeal joint.

21. The method of claim 20 wherein the surface is a concave surface and it is engaged with the head of the metapodial bone.

22. The method of claim 20 wherein the surface is a convex surface and it is engaged with the head of the proximal phalanx bone.

23. The method of claim 19 wherein the guide further comprises an alignment axis, the method further comprising: aligning the alignment axis parallel to the longitudinal axis of the metapodial bone.
