    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： Disclosed herein are unicompartmental femoral and tibial arthroplasty jigs for respectively assisting in the performance of unicompartmental femoral and tibial arthroplasty procedures on femoral and tibial arthroplasty target regions. The jigs each include a mating surface. The mating surface of the femoral jig is configured to matingly receive and contact a generally planar area of an anterior side of a femoral shaft generally proximal of the patellar facet border and generally distal an articularis genu. The mating surface of the tibial jig is configured to matingly receive and contact a generally planar area of an anterior side of a tibial shaft distal of the tibial plateau edge and generally proximal of the tibial tuberosity.

    摘要： A method and system for performing a total joint arthroplasty procedure on a patient's damaged bone region. A CT image or other suitable image is formed of the damaged bone surfaces, and location coordinate values (xn,yn,zn) are determined for a selected sequence of bone surface locations using the CT image data. A mathematical model z=f(x,y) of a surface that accurately matches the bone surface coordinates at the selected bone splice locations, or matches surface normal vector components at selected bone surface locations, is determined. The model provides a production file from which a cutting jig and an implant device (optional), each patient-specific and having controllable alignment, are fabricated for the damaged bone by automated processing. At this point, the patient is cut open (once), the cutting jig and a cutting instrument are used to remove a selected portion of the bone and to provide an exposed planar surface, the implant device is optionally secured to and aligned with the remainder of the bone, and the patient's incision is promptly repaired.

    摘要： Disclosed herein are unicompartmental femoral and tibial arthroplasty jigs for respectively assisting in the performance of unicompartmental femoral and tibial arthroplasty procedures on femoral and tibial arthroplasty target regions. The femoral and tibial unicompartmental arthroplasty jigs each include a first side, a second side and a mating surface. Each second side is generally opposite its respective first side. For the femoral jig, the mating surface is in the first side of the femoral jig and configured to matingly receive and contact a generally planar area of an anterior side of a femoral shaft generally proximal of the patellar facet boarder and generally distal an articularis genu. The first side of the femoral jig is configured to be oriented towards the femoral arthroplasty target region surface when the mating surface of the femoral jig matingly receives and contacts the planar area. For the tibial jig, the mating surface of the tibial jig is in the first side and configured to matingly receive and contact a generally planar area of an anterior side of a tibial shaft distal of the tibial plateau edge and generally proximal of the tibial tuberosity. The first side of the tibial jig is configured to be oriented towards the tibial arthroplasty target region surface when the mating surface of the tibial jig matingly receives and contacts the planar area.
