Systems and methods of tensioning a joint are disclosed herein. Trackers are affixed to the anatomy of the joint and the joint is adjusted into a fixed pose. In the fixed pose, a force is applied to the joint using a joint tensioner. The force is measured by the joint tensioner while a tracking system simultaneous captures the displacement of the joint generated by the force. A force-displacement relationship is generated based on the measured force and the captured displacement. The force-displacement relationship is used to determine a patient-specific tensioning force and to perform surgical planning.

The impactor includes an electromagnetic component that has a stationary electromagnetic housing and a moving magnet actuator, a striker, and one or more strike plates. The striker is coupled to an object. The stationary electromagnetic housing includes a coil that receives an electric current. The moving magnet actuator includes one or more magnets. The magnets generate a high potential magnetic field that interacts with the electric current applied to the coil disposed within the stationary electromagnetic housing and trigger translation movement of the moving magnet actuator. The electromagnetic field, generated as a result of application of the electric current to the coil, forces the moving magnet actuator to translate. Translation of the moving magnet actuator causes the moving magnet actuator to strike at least one of the strike plates to thereby translate the striker.

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.
