wherein the second opening extends through the first arm from the top surface through the bottom surface and the second opening is angled relative to the extension member.

14. The guide system of claim 12 , wherein the second arm comprises:

a second tapered body with a first end coupled to the second end of the base portion and a second end;

a third opening positioned near the second end of the second tapered body; and

a fourth opening positioned near the second end of the second tapered body and spaced apart from the first opening.

15. The guide system of claim 14 , wherein the third opening extends through the second arm from a top surface through a bottom surface of the second arm and the second opening extends parallel to the extension member; and

wherein the fourth opening extends through the second arm from the top surface through the bottom surface and the fourth opening is angled relative to the extension member.

16. The guide system of claim 3 , wherein the base portion further comprises

a recessed region extending into the base portion from the bottom surface toward a top surface of the base portion.

17. The guide system of claim 1 , wherein the base portion of the alignment guide comprises:

at least one opening extending through the base portion from a first end to a second end.

18. The guide system of claim 17 , wherein the directional wire is inserted through an opening of the at least one opening of the alignment guide.

19. The guide system of claim 1 , further comprising:

a position rotation device.

20. A method for using a guide system, comprising:

obtaining a cut guide, wherein the cut guide comprises:

a base portion;

an extension member extending away from a bottom surface of the base portion; and

at least one arm extending away from an end of the base portion;

inserting the extension member into a joint space;

coupling an alignment guide to the cut guide;

inserting a directional wire into at least one opening in the alignment guide;

inserting a first wire into a hole in the cut guide and checking an orientation of the cut guide;

inserting at least two second wires through the at least one arm of the cut guide and into at least one bone;

removing the alignment guide and the first wire;

cutting at least one of a first bone and a second bone using at least one slot of the cut guide;
