at least one angled opening extending through the base from the top surface to the bottom surface.
4. The osteotomy system of claim 3 , wherein the at least one angled opening includes at least one angled opening with a zero degree angle relative to a side surface of the alignment device.
5. The osteotomy system of claim 3 , wherein the at least one angled opening includes at least one angled opening with an angle greater than zero degrees.
6. The osteotomy system of claim 1 , wherein the cut guide comprises:
a proximal end;
a distal end opposite the proximal end;
an extension member extending from the cut guide on the distal end; and
at least one opening positioned adjacent to the proximal end; and
wherein the at least one slot is positioned between the distal end and the at least one opening.
7. The osteotomy system of claim 1 , wherein the cut guide comprises:
a top surface;
a bottom surface opposite the top surface;
a securement opening positioned at a first end of the cut guide and extending through the cut guide from the top surface to the bottom surface; and
at least one opening positioned at a second end of the cut guide and extending through the cut guide from a top surface to a bottom surface; and
wherein the at least one slot is positioned between the first end and the second end and extending through the cut guide from a top surface to a bottom surface.
8. The osteotomy system of claim 2 , wherein the position rotation device comprises:
a base with a first end and a second end, wherein the base is curved from the first end to the second end;
at least one angle opening extending through the base; and
a shaft coupled to the top surface of the base and extending away from the base.
9. The osteotomy system of claim 1 , wherein the bone plate comprises:
a first portion;
a second portion coupled to the first portion;
at least one first opening positioned in the first portion;
at least one second opening position in the second portion; and
wherein the second portion is curved as it extends away from the first portion.
10. An osteotomy kit, comprising:
an alignment device;
a cut guide, wherein the cut guide comprises:
a top surface;
a bottom surface opposite the top surface;
a securement opening positioned at a first end of the cut guide and extending through the cut guide from the top surface to the bottom surface;
at least one opening positioned at a second end of the cut guide and extending through the cut guide from a top surface to a bottom surface; and
a cutting slot positioned between the first end and the second end and extending through the cut guide from a top surface to a bottom surface;
a position rotation device;
at least one bone plate; and
at least one compression screw alignment guide for removeably coupling to the at least one bone plate.
11. A surgical method, comprising:
inserting a first k-wire into a bone;
sliding an alignment device over the first k-wire and into contact with the bone;
inserting a second k-wire through the alignment device and into the bone that corresponds to a rotation angle;
removing the first k-wire and the alignment device;
determining a hole in a cut guide that corresponds to an osteotomy cut angle;
positioning the cut guide on the bone and inserting a third k-wire into a distal end of the cut guide;
guiding a sagittal saw through the cut guide and cutting the bone to form an osteotomy site;
removing the cut guide;
rotating the distal end of the bone with respect to the proximal end to a desired angle of rotation; and
securing the rotated bone.
12. The method of claim 11 , wherein inserting the first k-wire into the bone comprises:
determining a point of insertion for the first k-wire;
positioning the foot relative to a foot plate guide; and
inserting the first k-wire through a k-wire guide of the foot plate guide perpendicular to the long axis of the bone.
13. The method of claim 11 , further comprising:
completing the cut through the bone after removing the cut guide.
14. The method of claim 11 , wherein rotating the distal end of the bone with respect to the proximal end to the desired angle of rotation comprises:
obtaining a position rotation device;
sliding the position rotation device over the third k-wire and into contact with the bone;
inserting a fourth k-wire into an opening corresponding to the rotation angle;
removing the third k-wire and the position rotation device; and
rotating the distal end and proximal end of the bone to the desired angle of rotation.
15. The method of claim 11 , wherein securing the rotated bone comprises:
coupling an alignment guide to a plate;
positioning the plate over the osteotomy site; and
securing the plate to the bone.
16. The method of claim 15 , wherein securing the plate to the bone comprises:
inserting at least two bone fasteners through the plate and into the bone; and
inserting a cross-screw across the osteotomy site.
17. The method of claim 16 , wherein the at least two bone fasteners are inserted before the cross-screw.
18. The method of claim 16 , wherein the cross-screw is inserted before the at least two bone fasteners.
19. The method of claim 16 , wherein the cross-screw is inserted using the alignment guide.
