Preoperative image studies including plain film radiography, computed tomography<span><span>, and magnetic resonance imaging provide only two-dimensional (2D) images and limited information about these severe deformities. In addition, these studies cannot directly offer visual or tactile feedback for surgeons and patients. On the contrary, the rapid prototyping (RP) technique provides surgeons with full-scale, 3D models, which make more accurate and more direct </span>morphometric<span><span> information of the complex spinal deformity obtainable. In this study, we intend to share our experience with the RP technique in pediatric spine deformity cases and to provide a literature review. In our study, two patients with severe spinal deformity were included. A real-size spinal model was produced for each patient on the basis of contiguous computer tomography with a slice thickness of 1 mm. All models were used to plan the resection and to identify the anatomic landmarks<span><span> during the operation. With the aid of these full-scale spinal models, all surgical procedures were performed exactly according to the preoperative plan. A 16-year-old girl with congenital scoliosis with a Cobb angle greater than 90° received staged surgery, including </span>vertebral column resection, correction, and posteriolateral </span></span>spinal fusion.
