Biplane Fluoroscopic Analysis of the Hindfoot Using Model-Based Tracking Techniques: A Static Phantom Study

Year: 2013

Type: article

Abstract: Dynamic assessment of skeletal kinematics is necessary for understanding normal joint function, in addition to effects of injury or disease [1, 2]. Conventional methods of motion analysis track skin-mounted optical markers with cameras to determine joint motion of the underlying bones. While these methods are simple, easy to implement and appropriate for various clinical and research related applications, they have been found to suffer from error due to movement (artifact) of the skin on which the markers are placed [3]. Due to the numerous bones and articulating surfaces within the foot and ankle, several rigid body assumptions are made to divide the foot into multiple segments for motion analysis. This method does not allow for obtaining inter-tarsal kinematics or kinetics of the hindfoot. A technique that locates the talus during gait analysis would allow for more advanced subtalar motion assessment and a more accurate estimate of hindfoot kinetics.
