GENERATION OF A COMPUTERIZED BONE MODEL REPRESENTATIVE OF A PRE-DEGENERATED STATE AND USEABLE IN THE DESIGN AND MANUFACTURE OF ARTHROPLASTY DEVICES
First Claim
1. A method of generating a restored bone model representative of at least a portion of a patient bone in a pre-degenerated state, the method comprising:
- determining reference information from a reference portion of a degenerated bone model representative of the at least a portion of the patient bone in a degenerated state; and
using the reference information to restore a degenerated portion of the degenerated bone model into a restored portion representative of the degenerated portion in the pre-degenerated state.

Abstract
Disclosed herein is 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. Also disclosed herein is a customized arthroplasty jig manufactured according to the above-described method. The customized arthroplasty jig is configured to facilitate a prosthetic implant restoring a patient joint to a natural alignment. The prosthetic implant may be for a total joint replacement or partial joint replacement. The patient joint may be a variety of joints, including, but not limited to, a knee joint.

38. A method of generating a computerized bone model representative of at least a portion of a first patient bone in a pre-degenerated state, the method comprising:
-
generating at least one image of the first patient bone in a degenerated state; identifying a reference portion associated with a generally non-degenerated portion of a second patient bone; identifying a degenerated portion associated with a generally degenerated portion of the first 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. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)

59. A method of generating a computerized bone model representative of at least a portion of a first patient bone in a pre-degenerated state, wherein the first patient bone is part of a first patient joint, the method comprising:
-
identifying a second patient bone of a second joint, wherein the second bone is a generally symmetrical mirror image of the first patient bone; generating a plurality of images of the second patient bone when the second patient bone is in a generally non-degenerated state; mirroring the plurality of images to reverse the order of the plurality images; and compiling the plurality of images in the reversed order to form the computerized bone model representative of the at least a portion of the first patient bone. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66)
