Arthroplasty devices and related methods
Arthroplasty jigs and related methods are disclosed. Some of the arthroplasty jigs may comprise a jig body that is configured to align with a surface of a bone, and a positioning component. Certain of the methods may comprise providing such an arthroplasty jig, and aligning the jig body with a surface of a bone so that the positioning component provides at least one of a visible, audible, or tactile indication that such alignment has been achieved. Some of the arthroplasty jigs may comprise a jig body that is configured to align with a surface of a bone, and that is marked with identifying information. Certain of the methods may comprise providing an arthroplasty jig comprising a jig body that is configured to align with a surface of a bone, or providing an arthroplasty jig blank, and marking the arthroplasty jig or the arthroplasty jig blank with identifying information.
1. A customized arthroplasty jig for facilitating an arthroplasty procedure on a bone of a patient, the bone having a joint region, a shaft extending away from the joint region and a transition region between the joint region and the shaft, the joint region having an associated surface of at least one of cartilage or bone, the jig comprising:
a jig body of unitary construction and comprising:
a patient-specific jig surface configured to at least one of align with or position on the associated surface in a customized fashion, the patient-specific jig surface existing in the jig body prior to coming into contact with the associated surface, the patient-specific jig surface manufactured in a customized configuration particular to the associated surface of the patient;
a positioning component extending from the patient-specific jig surface and configured to contact the transition region or the shaft when the patient-specific jig surface is positioned on the associated surface in the customized fashion; and
a first aperture extending through the jig body and configured to guide the placement of a first pin into the bone.
2. The jig of claim 1 , wherein the bone is that of a femur.
3. The jig of claim 2 , wherein the joint region is a knee region.
4. The jig of claim 1 , wherein the bone is that of a tibia.
5. The jig of claim 4 , wherein the joint region is a knee region.
6. The jig of claim 1 , wherein the joint region is one of a hip region, shoulder region, or elbow region.
7. The jig of claim 1 , wherein the first pin is configured to secure the jig body to the bone.
8. The jig of claim 1 , wherein the patient-specific jig surface is at least a result of a manufacturing process including: forming at least one image of the joint region; forming a three-dimensional model of the joint region from the at least one image; and generating the patient-specific jig surface based at least in part on data determined from the three-dimensional model.
9. The jig of claim 1 , wherein the jig body further comprises a resection slot configured to guide a planar resection in the bone.
10. The jig of claim 1 , wherein the arthroplasty jig includes identifying information present on the jig body, the identifying information associated with at least one of the patient or a medical professional.
11. The jig of claim 10 , wherein the identifying information is engraved into the jig body.
12. The jig of claim 10 , wherein the identifying information is printed onto the jig body.
13. The jig of claim 10 , wherein the identifying information is provided on a label that is affixed to the jig body.
14. The jig of claim 10 , wherein the identifying information includes at least one of a patient name, a number associated with the patient, an identification of the bone, or an identification of the joint region.
15. The jig of claim 1 , wherein the jig body further comprises a second aperture configured to receive a rod therethrough, wherein, when the rod is positioned in the second aperture, the rod is configured to determine correct positioning of the patient-specific jig surface on the associated surface.
16. The jig of claim 15 , wherein the rod comprises a collar, and wherein a position of the collar relative to the second aperture determines correct positioning of the patient-specific jig surface on the associated surface.
17. The jig of claim 1 , wherein the jig body further comprises a second aperture configured to receive a rod therethrough, wherein, when the rod is positioned in the second aperture, the jig body and the rod are configured to be moved together on the bone until the patient-specific jig surface is correctly positioned on the associated surface.
18. The jig of claim 17 , wherein a position of the rod determines when the patient-specific jig surface is correctly positioned on the associated surface.
19. The jig of claim 1 , wherein the jig body further comprises an alignment indicator configured to provide visual indication that the patient-specific jig surface is correctly aligned with the associated surface.
20. The jig of claim 19 , wherein the alignment indicator is configured to indicate when the jig body is in a level orientation.
21. The jig of claim 19 , wherein the alignment indicator comprises a level.
22. The jig of claim 1 , wherein the jig body further comprises an alignment indicator configured to provide visual indication that the jig body is in a level orientation.
23. The jig of 22 , wherein the alignment indicator comprises a level.
