Abstract
Rapid prototyping technology, known as three-dimensional (3D) printing, and its use
in the medical field are advancing. Studies on severe bone deformity treatment with
3D printing showed benefits in postoperative outcomes thanks to this technology. Even
so, preoperative planning guidance for surgeons is lacking. This technical note describes
a practical step-by-step guide to help surgeons use this technology to optimize the
therapeutic plan with free license software and an intuitive interface. This study
aims to organize the 3D modeling process using a preoperative computed tomography
(CT) scan. This technology allows a deeper understanding of the case and its particularities,
such as the direction, planes, and dimensions of the deformity. Planning considering
these topics may reduce the surgical time and result in better functional outcomes
by understanding the deformity and how to correct it. Associating planning via software
with 3D printing can further enhance this therapeutic method.
