GENERATION OF A COMPUTERIZED BONE MODEL REPRESENTATIVE OF A PRE-DEGENERATED STATE AND USEABLE IN THE DESIGN AND MANUFACTURE OF ARTHROPLASTY DEVICES

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, including 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 model in defining manufacturing instructions for the manufacture of a customized arthroplasty jig. A customized arthroplasty jig may be manufactured according to the above-described method and is configured to facilitate a prosthetic implant restoring a patient joint to a natural alignment.
