An intraoperative stereovision system has a stereo imager configured to provide stereo images at first and second time (iSV0, iSV(n)) to an image processor configured with a computerized mechanical model of a spinal column, the computerized mechanical model configured to model vertebrae as rigid, displaceable, bodies. The image processor is configured to extract an iSV0 surface model from iSV0 and an iSV(n) surface model from the iSV(n); to register these surfaces, and identify differences therefrom. The image processor is configured to adjust the computerized mechanical model according to the identified differences thereby causing the adjusted computerized mechanical model to track the iSV(n) surface model at each of multiple timepoints.
