Patent number: 10363052Abstract: A 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 slice 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.Type: GrantFiled: January 8, 2019Date of Patent: July 30, 2019Assignee: Howmedica Osteonics CorporationInventors: Ilwhan Park, Lacerial Pearson, Stephen M.
