The three dimensional (3D) in vivo kinematic behavior of the ankle joi
nt was evaluated using spiral volumetric CT scanning of a normal adult
foot. The CT data were reconstructed and interpolated to create an is
otropic 3D data volume. These data were rendered, visualized, segmente
d into their bony elements, labeled, and exported to disk using Mayo A
nalyze(TM) software. The labeled 3D CT datasets were analyzed to deter
mine relative orientation, translation, and rotation of the tibia-talu
s, tibia-calcaneus and calcaneus-talus. Using these results, the 3D mo
tion characteristics during normal adult foot flexion/extension were d
escribed quantitatively.
