Abstract: Surgical systems and methods involve a first and second trackers with trackable elements and which are independently secured to a bone and separated by a distance. A localizer tracks the trackable elements. Controller(s) define a tracking arrangement based on a combination of the trackable elements from the trackers. The controller(s) register a geometry of the tracking arrangement relative to the bone and track the bone by detection of the registered geometry. The controller(s) detect a condition wherein at least one trackable element has been displaced relative to the registered geometry. The controller(s) register a position of an anatomical landmark of the bone and use the landmark to identify the at least one trackable element that has been displaced.

Abstract: A tracker for a navigation system. A tracker body defines an opening, and a lens is positionable to seal the opening. A plug is configured to be coupled to the tracker body to secure the lens. A tracking element may be disposed between the lens and the plug so as to be visible through the lens. The tracking element may be disposed within a sealed enclosure defined by the lens and the plug. The plug may define a counterbore in fluid communication with the opening, and the plug may be at least partially disposed within the counterbore. The plug may further define a groove, and the tracker may include a sealing element disposed within the groove. The plug may include a shoulder configured to in sealing engagement with the tracker body. Methods of assembling the tracker for use with the navigation system are also disclosed.

Abstract: A navigation system is disclosed which comprises a tracker having a trackable feature, a localizer configured to track states of the trackable feature within a field of view, an illumination assembly operable to direct light within the field of view, and a controller coupled to the localizer and to the illumination assembly. The controller is configured to receive the tracked states from the localizer, to determine a status condition of the tracker based on the tracked states received from the localizer, and to control the illumination assembly to direct light at the tracker such that light reflected by the tracker from the illumination assembly is visible to a user of the navigation system to communicate the status condition of the tracker.
