ABSTRACT:
A fixture is attached to the bones using external fixation techniques to trace a representation of the polycentric motion of a joint. The fixture has two plates attached to bones on respective sides of the joint. The plates are unconnected to each other and free to move relative to each other. The motion may be recorded using a stylus that traces a track in a deformable medium.
