For measuring the in-vivo range-of-motion of the ankle joints, a semi-automated Computer Tomography based bone contour method (CT/BCM) was developed to determine the three-dimensional position and orientation of the bones. To validate this technique, we hypothesized that the range of motion in the ankle is at least equally accurately measured by Roentgen Stereophotogrammetric Analysis (RSA) as by the CT/BCM technique.
