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 the 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:
positioning a cutting guide relative to a first bone with a locating device, 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 a pin through a through-bore of the locating device and the first bone in the first direction, wherein the locating device includes a body having a first and a second side, the first side including a surface that is complementary to a 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 complementary surface and the surface of the second side, wherein the recessed surface is sized to receive a cutting guide, and a plurality of slots are defined through the recessed surface.
2. The method of claim 1 , comprising:
placing the locating device in contact with the first bone such that the complementary surface securely engages the anatomical surface of the first bone.
3. The method of claim 1 , comprising:
resecting the first bone after inserting a cutting device into at least one of the first slot, the second slot, and the third slot.
4. The method of claim 1 , wherein the recessed surface receives a portion of the cutting guide.
5. The method of claim 4 , wherein positioning the cutting guide using the locating device includes inserting the cutting guide into the recess.
6. A method, comprising:
securing a first side of a locating device in contact with a first bone, the locating device having a body with a first side and a second side, the first side including a surface that is complementary to an 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 complementary surface and the surface of the second side, wherein the recessed surface is suitable for receiving a cutting guide such that the plurality of slots are defined through the recessed surface;
inserting a pin through a bore defined in the locating device so as to engage the first bone such that 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;
moving a cutting guide into position according to a placement of the locating device;
inserting a cutting tool into a slot of the plurality of slots; and
resecting the first bone.
7. The method of claim 6 , wherein the plurality of slots 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.
8. The method of claim 6 , wherein moving the cutting guide into position includes placing the cutting guide into the recessed surface defined by the second side of the locating device such that the fourth slot aligns with the first slot, the fifth slot aligns with the second slot, and the sixth slot aligns with the third slot.
9. The method of claim 6 , comprising removing the pin prior to resecting the first bone.
