Claim:
1. A method of intraoperatively verifying the position and orientation of an intraoperatively inserted orthopedic insert, comprising: generating a preoperative three dimensional image data set showing at least a bone in which said insert is to be inserted; generating a plurality of intraoperative two-dimensional fluoroscope images showing said insert and said bone, each image taken at a known orientation and position relative to said bone; reconstructing from said plurality of intraoperative two-dimensional fluoroscope images, an intraoperative three dimensional image data set including the three dimensional position and orientation of said insert; registering said intraoperative three dimensional image data set with said preoperative three dimensional image data set; using said previously determined registration to modify said preoperative three dimensional image data set by insertion therein of the three dimensional position and orientation of said insert; and generating at least one two dimensional image from said modified preoperative three dimensional image data set, with a virtual image of said intraoperatively inserted orthopedic insert implanted therein, such that the position and orientation of said intraoperatively inserted orthopedic insert may be verified intraoperatively on an image having the characteristics of a preoperatively generated image.
