INTRODUCTION: Preoperative 3D modeling allows more effective diagnosis and simulates the surgical procedure. Objectives: Our goal for this study was to show a new methodology for applying 3D technology thru Do It Yourself processing.
METHODS: We report 10 cases of acetabular fractures with preoperative planning performed by pre-molding synthesis plates on a 3D printed mold obtained from the CT scan. After obtaining the printed hemipelvis, plate precontouring was performed using the templates available, adapting their shape to the anatomical contours.
RESULTS: Templates were contoured over the plastic model; then reproducing these plate models in the final plates with the aid of standard plate-benders during 25 minutes (mean). The plastic consumption for printing the model was 295 g of ABS, so we printed our model for less than 12 euros. No intraoperative modifications were required. The postoperative CT scan showed an anatomical reduction and no gaps were observed between the plates and the acetabular surface after rendering the images.
CONCLUSIONS: The use of preoperative planning, by printing 3D mirror imaging models of the opposite hemipelvis and precontouring plates over the mold, lead to effectively achieve a predefined surgical objective and to reduce the inherent risks.
