摘要： 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.

摘要： A method of manufacturing an arthroplasty jig is disclosed herein. The method may include the following: generate a bone model, wherein the bone model includes a three dimensional computer model of at least a portion of a joint surface of a bone of a patient joint to undergo an arthroplasty procedure; generate an implant model, wherein the implant model includes a three dimensional computer model of at least a portion of a joint surface of an arthroplasty implant to be used in the arthroplasty procedure; assess a characteristic associated with the patient joint; generate a modified joint surface of the implant model by modifying at least a portion of a joint surface of the implant model according to the characteristic; and shape match the modified joint surface of the implant model and a corresponding joint surface of the bone model.

摘要： A computer-implemented method of preoperatively planning a surgical procedure on a knee of a patient including determining femoral condyle vectors and tibial plateau vectors based on image data of the knee, the femoral condyle vectors and the tibial plateau vectors corresponding to motion vectors of the femoral condyles and the tibial plateau as they move relative to each other. The method may also include modifying a bone model representative of at least one of the femur and the tibia into a modified bone model based on the femoral condyle vectors and the tibial plateau vectors. And the method may further include determining coordinate locations for a resection of the modified bone model.

摘要： A method of generating a computerized bone model representative of at least a portion of a patient bone in a pre-degenerated state. The method includes: generating at least one image of the patient bone in a degenerated state; identifying a reference portion associated with a generally non-degenerated portion of the patient bone; identifying a degenerated portion associated with a generally degenerated portion of the patient bone; and using information from at least one image associated with the reference portion to modify at least one aspect associated with at least one image associated the generally degenerated portion. The method may further include employing the computerized bone model representative of the at least a portion of the patient bone in the pre-degenerated state in defining manufacturing instructions for the manufacture of a customized arthroplasty jig.
