1_9. ] A computer assisted surgery system with enhanced graphic capabilities for insertion of guide pins into a body part, the system comprising:

  • an x-ray imaging device for generating at least one 2-D image of a body part;

    means for displaying the at least one 2-D image of the body part;

    a surgical instrument with a physical feature defining a real trajectory;

    a localizing device for measuring the pose of the surgical instrument;

    means for generating a graphic representation of the real trajectory;

    means for determining the location of one or more virtual trajectories relative to the real trajectory; and

    means for superimposing graphic representations of the real and virtual trajectories over the at least one 2-D image of the body part;

    wherein the virtual trajectories may be used for assisting the surgeon in aligning the drill guide relative to the body part or guide pins and said virtual trajectories need not represent a real feature of the surgical instrument.
