Biplane fluoroscopy can directly track the motion of bones and therefore measure joint kinematics. Our prior marker-based work has demonstrated the ability of our system to accurately and precisely track the motion of known objects (i.e., tantalum beads) . In this study, we present the preliminary bone-based validation of our system by tracking the bones of the foot from cadaveric specimens.
Individual bone accuracy and precision values, along with grand values for the six bone set.
These translational accuracy and precision values match well with other similar dual fluoroscopy systems studying areas of the body such as the spine  and knee . Further, these values are an order of magnitude improvement over optical motion capture systems and have the ability to measure kinematics which are traditionally difficult to capture in the foot, such as talar motion. The full model-based validation of this system (which includes rotational and dynamic trials) is currently underway.
The work was funded by VA RR&D Grant F7468R.
