Abstract:
1. A non-transitory computer readable storage medium storing computer executable instructions which, when executed on a computer, form a method comprising: choosing a desired subject bone type having a naturally occurring void volume associated therewith; obtaining a plurality of three dimensional reference bone models, each reference bone model corresponding to a sample reference bone of the desired subject bone type, and each sample reference bone having substantially non-pathologic native anatomy; merging the plurality of reference bone models to define an average void shape based upon the plurality of reference bone models; using the average void shape to create a three-dimensional reference anatomic model, the reference anatomic model representing an average shape of void volumes in the plurality of reference bone models; employing the reference anatomic model in a comparison of pathologic native anatomy of a patient bone of the desired subject bone type to non-pathologic native anatomy; creating a three-dimensional patient bone model of a patient bone that mates with the patient bone of the desired subject bone type; identifying at least one structural difference between the patient bone model and the reference anatomic model; and modifying the created patient bone model based on the identified structural difference between the patient bone model and the reference anatomic model for use in creating prosthetic bone component.
