providing a shaft of a surgical instrument configured to be positioned adjacent to a tissue cavity;
providing the shaft for delivery of bone graft through the shaft and into the tissue cavity;
providing a tracking device with the surgical instrument to communicate a signal representative of a position of distal end of the shaft of the surgical instrument relative to the tissue cavity;
operating a processor to:
display an image of the tissue cavity,
track the distal end of the shaft relative to the tissue cavity,
project overlapping projections from the distal end of the shaft of the shaft at the tracked position of the distal end of the shaft on the displayed image of the tissue to generate data for display of the projected overlapped projections relative to the image of the tissue cavity; and
comparing the projected overlapped projections relative to the image of the tissue cavity to determine a volume of the tissue cavity.
