Abstract:
1. A system for tracking the progress of insertion of a rod in a bone including: a plurality of sensors including a first sensor attached to a reducing rod and a second sensor adapted to be attached to a first bone fragment, at least one of said first and second sensors configured to determine a position of said first sensor relative to said second sensor; and a computer configured to display a location of said rod based on at least a pose of a central canal of said first bone fragment relative to said second sensor, dimensional data of said rod relative to said first sensor, and said position of said first sensor relative to said second sensor and determine the trajectory of said rod after it has passed through the first bone fragment and is moving toward a second bone fragment and compare the trajectory of said rod with a central canal of the second bone fragment and provide a warning if the trajectory of the rod is not aligned with the canal of the second bone fragment.
