Patent Images

1. A method of creating a customized arthroplasty jig, the method comprising:

  • generating two-dimensional MRI images of a patient'"'"'s joint area to undergo arthroplasty, wherein the MRI images are between approximately 128×

    128 to approximately 1024×

    1024 resolution and between approximately 1 mm and approximately 4 mm slice spacing;

    generating a three-dimensional bone image of at least a portion of a bone of the patient'"'"'s joint area from the generated two-dimensional MRI images;

    using the three-dimensional bone image to generate data pertaining to the customized arthroplasty jig, wherein the data includes bone surface information;

    providing the data to at least one manufacturing device; and

    employing the bone surface information to cause the at least one manufacturing device to create a surface on the arthroplasty jig configured to matingly receive a surface of the bone.
