Claim 6:
7. A system for computer-assisted navigation during surgery, the system comprising:
a robotic navigation system including a computer, a display coupled to the computer, and a camera coupled to the computer and configured to detect tracking markers;
a first dynamic reference base including a first reference array having a plurality of tracking markers trackable by the camera, the first dynamic reference base configured to attach to and track a first bone;
a second dynamic reference base including a second reference array with a plurality of tracking markers trackable by the camera, the second dynamic reference base configured to attach to and track a second bone; and
a navigable stylus including:
an elongate body defining a longitudinal axis;
a third reference array disposed at a proximal portion of the elongate body and having a plurality of tracking markers trackable by the camera, the third reference array including an array frame and a shaft extending distally from the array frame, wherein three of the third reference array tracking markers are attached to the array frame and one of the third reference array tracking markers is distally spaced from the three third reference array tracking markers and attached to the shaft; and
wherein the robotic navigation system is adapted to determine a position of the surgical instrument attached to the stylus using only the third reference array regardless of which surgical instrument is attached to the navigable stylus

wherein a plurality of surgical instruments configured to connect to the stylus, wherein the stylus includes a plane checker,
wherein the plane checker includes a collar and a foot, wherein the collar includes a longitudinal opening configured to receive the universal quick-connect attachment tip, and the foot includes a U-shaped plate with a flat bottom surface configured to be placed on a resection plane to return an angulation and/or cut depth to the robotic navigation system.
