Guides, instruments, systems and methods of use
Guides, instruments, devices, systems and methods for maintaining, correcting and/or resurfacing the multiple bones of a joint are disclosed. The guide system includes a cut guide and an alignment guide for engagement with the cut guide. The guide system also includes a cleaning system with a guide and a cutting instrument. Methods of using the guide system and cleaning system are also disclosed.
1. A guide system, comprising:
a cut guide comprising a first end and a second end, wherein the cut guide is curved from the first end to the second end, the cut guide further comprising:
a base portion, having a top surface and a bottom surface, wherein the base portion comprises:
at least one slot positioned between a first side and a second side of the base portion;
an extension member extending away from the bottom surface of the base portion, wherein the extension member is tapered in at least one of a proximal-distal direction, a medial-lateral direction, and a proximal-distal direction as it extends away from the bottom surface of the base portion; and
at least one arm extending away from at least one end of the base portion; and
an alignment guide for engagement with the cut guide,
wherein the slot extends from the top surface of the base portion through the bottom surface of the base portion and through the extension member.
2. The guide system of claim 1 , wherein the extension member comprises:
a first end, wherein the first end is coupled to the bottom surface of the base portion; and
a second end.
3. The guide system of claim 1 , wherein the at least one arm comprises:
a first arm extending away from a first end of the base portion; and
a second arm extending away from a second end of the base portion.
4. The guide system of claim 3 , wherein the first arm comprises:
a body with a first end and a second end, wherein the first end is coupled to a first end of the base portion; and
at least one hole positioned near the second end of the first arm.
5. The guide system of claim 4 , wherein the at least one hole of the first arm comprises:
a first hole positioned near the second end of the body; and
a second hole positioned near the second end of the body, wherein the second hole is spaced apart from the first hole, and wherein the first hole and the second hole are angled with respect to each other and the angle is selected from a converging angle or a diverging angle.
6. The guide system of claim 3 , wherein the second arm comprises:
a body with a first end and a second end, wherein the first end is coupled to a second end of the base portion.
7. The guide system claim 6 , wherein the second arm further comprises:
at least one hole positioned near the second end of the second arm.
8. The guide system of claim 7 , wherein the at least one hole of the second arm comprises:
a third hole positioned near the second end of the body; and
a fourth hole positioned near the second end of the body, wherein the fourth hole is spaced apart from the third hole, and wherein the third hole and the fourth hole are angled with respect to each other and the angle is selected from a converging angle or a diverging angle.
9. The guide system of claim 1 , wherein the alignment guide comprises:
a shaft portion; and
an extension portion coupled to and extending away from the shaft portion.
10. The guide system of claim 9 , wherein the alignment guide further comprises:
a coupling portion positioned between the shaft portion and the extension portion, wherein the coupling portion is tapered from the shaft portion to the extension portion.
11. The guide system of claim 10 , wherein the shaft portion comprises:
a first side with at least one recess; and
a second side with at least one recess.
12. The guide system of claim 1 , further comprising:
a cleaning system, wherein the cleaning system comprises:
a cutting instrument; and
a cleaning guide with a first end and a second end.
13. The guide system of claim 12 , wherein the cleaning guide comprises:
a recess inset into a top surface of the cleaning guide; and
an opening extending through the recess from the top surface to a bottom surface of the cleaning guide.
14. The guide system of claim 12 , wherein the cutting instrument is received through an opening of the cleaning guide.
15. The guide system of claim 14 , wherein the cutting instrument comprises:
a shaft having a proximal end and a distal end; and
a cutting portion coupled to and extending away from the proximal end of the shaft.
16. The guide system of claim 1 , further comprises:
at least one wire or pin for engaging the cut guide.
17. The guide system of claim 1 , wherein the extension member comprises a generally conical shape with an elliptical or oval-shaped cross-section.
18. A method for using a guide system, comprising:
obtaining a cut guide, wherein the cut guide comprises:
a base portion with a top surface and a bottom surface;
an extension member extending away from the bottom surface of the base portion, wherein the extension member is tapered in at least one of a proximal-distal direction, a medial-lateral direction, and a proximal-distal direction as it extends away from the bottom surface of the base portion; and
at least one arm extending away from at least one end of the base portion;
making an incision to expose a joint with a first bone and a second bone;
inserting an alignment guide into a joint space;
coupling the cut guide to the alignment guide;
inserting at least one wire through at least one hole in the cut guide and into at least one of the first bone and the second bone;
checking the alignment of the cut guide;
removing the alignment guide from the cut guide;
inserting a cutting instrument through a slot in the cut guide to remove at least a portion of the first bone or the second bone;
removing the at least one wire from the at least one of the first bone and the second bone and the cut guide; and
aligning the joint for fixation.
