摘要： The present application provides an apparatus and method for determining a position of a joint prosthesis using a computer assisted orthopedic surgery system in support of an arthroplasty surgery. The apparatus and method includes attaching a first locatable element to a first bone on one side of a joint, providing a sensor having a second locatable element and moving the sensor in proximity of the joint to locate a plurality of positions of the sensor relative to the first locatable element using a tracking devise. The apparatus and method further includes selecting a generic model of a joint, determining the generic model in response to the plurality of positions located using the tracking device to generate a deformed model, determining a position for a joint prosthesis on the deformed model, and outputting on a display the determined position upon the deformed model.

摘要： A computer-assisted orthopedic surgery system includes a device for generating a three dimensional geometrical surface model of a first bone and a database containing three 3 dimensional implant models of a plurality of available implants. The system includes a computer that is configured to permit a user to select from the database a first implant and display on a screen the three dimensional implant model of the first implant. The computer superimposes on the screen the implant model on top of the model of the first bone such that the two models are visually identifiable from one another.
