SYSTEM AND METHOD FOR DETERMINING TIBIAL ROTATION

摘要

A system and method for determining tibial rotation is disclosed. The system includes a first fiducial, a second fiducial, a position and orientation sensor, a computer, and a monitor. The first fiducial is connected to a first part, and the second fiducial is connected to a second part. The position and orientation sensor tracks the first fiducial and the second fiducial. The computer has a memory, a processor, and an input/output device. The input/output device receives data from the position and orientation sensor. The processor processes the data to identify a first axis of the first part and a second axis of the second part. The processor constructs a reference plane through the second axis and orthogonal to the first axis. The monitor is connected to the input/output device and displays a rendering of the reference plane.
