Abstract: An intramedullary (“IM”) nail and surgical technique or method. The IM nail includes a body including an opening for receiving a lag screw and a compression screw. The body further including one or more screw openings for receiving a bone screw. The surgical technique enables a surgeon to selectively prevent or allow movement (e.g., medialization) of the IM nail within the patient's intramedullary canal. The position of the IM nail can be selectively secured within the patient's intramedullary canal depending on surgeon preference and/or depending on the fracture pattern being treated. In use, the surgeon can elect to either secure the position of the IM nail within the patient's intramedullary canal thereby preventing movement (e.g., medialization) of the IM nail within the patient's intramedullary canal, or the surgeon can allow the IM nail to move (e.g., medialize) within the patient's intramedullary canal.

Abstract: An augmented reality system and method for assisting surgical staff during an arthroplasty procedure includes a camera system configured to capture images of a surgical scene and a processor configured to determine from the images location and orientation information about one or more patient anatomical features and to maintain a three-dimensional model of these anatomical features within the surgical scene.

Abstract: Methods, non-transitory computer readable media, tracker devices, central processor devices, and optical tracking systems that facilitate improved optical tracking in surgical environments are disclosed. With this technology, background images are captured within an acquisition sequence.
