Patent ID: 7383164

Claim:
A computer system that generates a set of artificial implant model data used to fabricate an artificial implant that provides a set of ranges of motions for a joint depicted in joint motion image data for a plurality of corresponding joints in a plurality of subjects comprising: an anthropometric data analyzer executing on a computer for receiving joint motion image data representative of the plurality of corresponding joints in the plurality of subjects, and the received data being displayed by the anthropometric analyzer on a display to enable an operator to select points that identify a plurality of geometric dimensions and ranges of values for the identified geometric dimensions; an implant model generator executing on the computer, the implant model generator receiving the identified geometric dimensions and the ranges of values for the identified geometric dimensions that were generated by the anthropometric data analyzer and generating a set of artificial implant model data for fabricating the artificial implant that corresponds to the identified geometric dimensions and a set of discrete values for the identified geometric dimensions for the artificial implant from the identified geometric dimensions and the ranges of values for the identified geometric dimensions; a kinematic model simulator executing on the computer, the kinematic model simulator incorporating the set of artificial implant model data generated by the implant model generator in a kinematic model of the joint, and simulating movement of the joint with the kinematic model to generate motion versus time data; a motion data analyzer executing on the computer that compares the motion versus time data generated by the kinematic model simulator with motion versus time data from the joint motion image data used to identify the geometric dimensions and the ranges of values for the identified geometric dimensions that were used to generate the set of artificial implant model data to determine whether the artificial implant corresponding to the set of artificial implant model data provides the set of ranges of motions for the joint depicted in the joint motion image data; and a database coupled to the computer executing the motion data analyzer to receive and store the set of artificial implant model data in a database file, in response to the motion data analyzer determining the artificial implant corresponding to the set of artificial implant model data provides the set of ranges of motions for the joint depicted in the joint motion image data to enable the artificial implant model data to be retrieved for fabricating the artificial implant.
