Patient specific surgical guide locator and mount
A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within he socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.
1. A method, comprising:
placing a first side of a locating device into contact with a first bone, the locating device having a body with opposed first and second sides, the first side including a conformal surface that is shaped to be complementary to a shape of a natural anatomical surface of the first bone, the body defining a plurality of slots each of which extends through the body, the body having a surface that is recessed relative to a surface of the second side such that the recessed surface of the body is disposed between the conformal surface and the surface of the second side, wherein the recessed surface is sized and configured to receive a cutting guide therein, and wherein the plurality of slots are defined through the recessed surface; and
securing the locating device to the first bone by inserting at least one pin through at least one through-bore of the locating device and into the first bone,
wherein a first slot of the plurality of slots extends in a first direction, a second slot of the plurality of slots extends in a second direction, and a third slot of the plurality of slots extends in a third direction.
2. The method of claim 1 , further comprising:
moving a cutting guide into position to resect the first bone based on a placement of the locating device; and
inserting a cutting tool into at least one of a plurality of slots defined by the cutting guide to resect the first bone.
3. The method of claim 2 , wherein the plurality of slots defined by the cutting guide includes a fourth slot extending in the first direction, a fifth slot extending in the second direction, and a sixth slot extending in the third direction.
4. The method of claim 2 , wherein moving the cutting guide into position includes placing the cutting guide into a recess defined by the second side of the locating device such that the fourth slot at least partially aligns with the first slot, the fifth slot at least partially aligns with the second slot, and the sixth slot at least partially aligns with the third slot.
5. The method of claim 1 , wherein the first bone is a tibia.
6. The method of claim 1 , further comprising removing the at least one pin prior to resecting the first bone.
7. A method, comprising:
using a locating device to position a cutting guide relative to a first bone, the cutting guide including a first slot extending in a first direction, a second slot extending in a second direction, and a third slot extending in a third direction, and
securing the locating device to the first bone by inserting at least one pin through at least one through-bore of the locating device and into the first bone,
wherein the locating device includes a body having opposed first and second sides, the first side including a conformal surface that is shaped to be complementary to a shape of a natural anatomical surface of the first bone, the body having a surface that is recessed relative to a surface of the second side such that the recessed surface of the body is disposed between the conformal surface and the surface of the second side, wherein the recessed surface is sized and configured to receive a cutting guide therein, and wherein the plurality of slots are defined through the recessed surface.
8. The method of claim 7 , further comprising:
placing the locating device in contact with the first bone such that the conformal surface of the locating device is aligned with the natural anatomical surface of the first bone.
9. The method of claim 7 , further comprising resecting the first bone by inserting a cutting device into at least one of the first slot, the second slot, and the third slot of the cutting guide.
10. The method of claim 7 , wherein the locating device defines a recess for receiving at least part of the cutting guide therein.
11. The method of claim 10 , wherein using the locating device to position the cutting guide includes inserting the cutting guide into the recess.
12. The method of claim 7 , wherein the first bone is a tibia.
13. A method, comprising:
providing a locating device, the locating device having a body with opposed first and second sides, the first side of the locating device including a conformal surface that is shaped to be complementary to a shape of a natural anatomical surface of a first bone, the body having a surface that is recessed relative to a surface of the second side such that the surface that is recessed is disposed between the conformal surface and the surface of the second side, wherein the plurality of slots are defined through the recessed surface;
providing a cutting guide, the cutting guide defining a first slot extending in a first direction, a second slot extending in a second direction, and a third slot extending in a third direction, wherein an outer perimeter of the cutting guide is received within the recess of the body;
securing the locating device to the first bone by inserting at least one pin through at least one through-bore of the locating device and into the first bone;
using the locating device to position the cutting guide relative to the first bone; and
resecting the first bone by inserting a cutting tool into at least one of the first slot, the second slot, and the third slot.
14. The method of claim 13 , wherein the first bone is a tibia.
15. The method of claim 14 , wherein using the locating device to position the cutting guide relative to the first bone includes placing the locating device in contact with the first bone such that the conformal surface of the locating device is aligned with the natural anatomical surface of the first bone.
16. The method of claim 13 , wherein the second side of the body of the locating device defines a recess sized and configured to receive at least a portion of the cutting guide.
17. The method of claim 16 , further comprising receiving at least the portion of the cutting guide within the recess.
