摘要： A system and method for pre-operatively optimizing a fit of an orthopedic implant relative to a particular individuals anatomy is provided. The method includes: receiving information including a three-dimensional anatomic model of the individuals anatomy; computing a periphery of a simulated resection portion of the anatomic model without reference to any abnormal morphology; identifying a preliminary size for an orthopedic implant component for use on the simulated resection surface; initially positioning the orthopedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopedic implant model; utilizing a position optimizer to determine whether the position of the orthopedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopedic implant model results in overhang; and verifying the position of the orthopedic implant and/or the size of the orthopedic implant.

摘要： A system and method for pre-operatively optimizing a fit of an orthopaedic implant relative to a particular individuals anatomy is provided. The method includes: receiving information including a three-dimensional anatomic model of the individuals anatomy; computing a periphery of a simulated resection portion of the anatomic model without reference to any abnormal morphology; identifying a preliminary size for an orthopaedic implant component for use on the simulated resection surface; initially positioning the orthopaedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopaedic implant model; utilizing a position optimizer to determine whether the position of the orthopaedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopaedic implant model results in overhang; and verifying the position of the orthopaedic implant and/or the size of the orthopaedic implant.
