Arthroplasty devices and related methods
View Patent ↗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 and a shaft extending away from the joint region, the joint region having an associated surface of at least one of cartilage or bone, the jig comprising:
a curvilinear jig surface configured to at least one of align with or position on the associated surface in a customized fashion, the curvilinear jig surface manufactured in a customized configuration particular to the associated surface of the patient; and
a positioning component being of a fixed unitary construction with the curvilinear jig surface and configured to contact the shaft when the curvilinear jig surface at least one of aligns with or positions on the associated surface in the customized fashion.
2. 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 curvilinear jig surface configured to at least one of align with or position on the associated surface in a customized fashion, the curvilinear jig surface manufactured in a customized configuration particular to the associated surface of the patient; and
a positioning component being of a fixed unitary construction with the curvilinear jig surface and configured to contact the transition region when the curvilinear jig surface at least one of aligns with or positions on the associated surface in the customized fashion.
3. The jig as in any of claims 1 or 2 , in which the joint region includes at least one femoral condyle.
4. The jig as in any of claims 1 or 2 , in which the joint region includes at least one tibia plateau.
5. The jig as in any of claims 1 or 2 , in which the curvilinear 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 jig surface based at least in part on data determined from the three-dimensional model.
6. The jig of claim 5 , wherein the at least one image is generated via at least one of MRI or CT.
7. The jig according to claims 1 or 2 , further comprising at least one of a cutting instrument guide, a drilling instrument guide or a pin delivery guide.
8. The jig as in any of claims 1 or 2 , in which the positioning component generally terminates in a contact-making free end including at least one of a pointed configuration or a rounded configuration.
9. The jig as in any of claims 1 or 2 , in which the arthroplasty jig includes identifying information present on a jig body of the arthroplasty jig, the identifying information associated with at least one of the patient or a medical professional.
10. The jig of claim 9 , wherein the identifying information is engraved into the jig body.
11. The jig of claim 9 , wherein the identifying information is printed onto the jig body.
12. The jig of claim 9 , wherein the identifying information is provided on a label that is affixed to the jig body.
13. The jig of claim 9 , 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.
14. The jig as in any of claims 1 or 2 , in which the bone is that of a femur.
15. The jig of claim 14 , wherein the joint region is a knee region.
16. The jig as in any of claims 1 or 2 , in which the bone is that of a tibia.
17. The jig of claim 16 , wherein the joint region is a knee region.
