Total joint arthroplasty system

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