Claim One:
1. A method for generating a display of a tracked surgical object relative to a non-imaged scaled general model in plane view of a vertebra in computer-assisted surgery, the method comprising: receiving a general model of the vertebra comprising features and dimension parameters related to said features, the general model being non patient specific; obtaining at least a first plane view of the anatomical part; identifying said features in said at least first plane view; measuring values of said dimension parameters from said features identified in said at least first plane view; generating said non-imaged scaled general model in a transverse plane view of the vertebra by scaling said general model with said dimension parameters adjusted to said values; tracking a surgical object relative to said vertebra while a user manipulates said surgical object in space; and displaying on a display device of a computer-assisted surgery system by generating a representation of said surgical object to be overlaid in register on said transverse plane view of the vertebra, using the tracking of the surgical object.
