Demonstration of the design of the three-dimensional (3D) model of the pectus bar. (A) Measurement indices using computed tomography. The maximum transverse chest diameter (a) was divided by the most posterior sternal compression sternovertebral (SV) distance (b). (B) Coronal view of the designed 3D printed model with two possible pectus bar implantation regions. (C) Axial view of the original chest contour (green) and prediction of the postoperative chest contour (yellow) model. The computer-aided design anteriorly moves the location of the original sternum. The length of the original SV is measured as (c), and the length of the predicted SV is measured as (d). (D) Clinical applications of the 3D model of the pectus bar used for surgical simulation.

3. Fig 2
Haller index measurement from chest radiographs after the Nuss operation. The point of the most posterior projection of the sternum was identified, and the sternovertebral distance (b) was measured. The transverse diameter (a) was measured from the anteroposterior view at the same vertebral level as the lateral view.
