Abstract

The present study aims to demonstrate how biomodels can be used as teaching tools for surgical techniques and training in a medical residency service. A case series was carried out in our orthopedics and traumatology outpatient facility using three-dimensional (3D) printing for surgical planning to contribute to the surgical teaching and training of resident physicians. Two cases were selected as examples in the present article. Biomodels enable a better understanding of the surgery by the surgical team and residents, reducing the surgical time and the risks for the patients. These models can be a good teaching method to plan reconstructions of total hip arthroplasties, evaluate and predict surgical difficulties, and optimize procedures.

Keywords: arthroplasty, replacement, hip; hip/surgery; models, anatomic; printing, three-dimensional.
