Abstract:

Fluoroscopy is a dynamic video X-ray imaging technology widely used in the field of orthopedic biomechanics for assessing joint or implant motion in conjunction with object tracking techniques. While many biomechanical models are driven by surface-based motion capture systems, when assessing joint biomechanics these surface-based systems are inherently flawed since they measures the motion of the skin over the bone rather than the bone itself. Fluoroscopy overcomes this by visualizing the positions of radiopaque objects (such as bones or implants) inside the body in near real time. The locations of these objects as they move can be quantified postprocessing and reported in 2D or 3D coordinate systems. This chapter describes the methods and applications of fluoroscopy in orthopedic biomechanics and provides examples of its utility in assessing kinematics in the foot, knee, and spine.
