3D Measurement of Anatomic Parameters and Development of a Digital Design to Improve the Outcome of Lower-Extremity Surgery

To overcome disadvantages of the older surgical model, we invented a new three-dimensional (3D) correction surgery design after studying computer-aided 3D model analysis. Three-dimensional reconstruction was carried out for computed tomographic (CT) scans of patients with normal bilateral lower extremities; an anatomical model was established; and the normal values of 3D anatomic parameters of the lower-extremity joints were measured with...
