Three-dimensional reconstruction (3D) and rapid prototyping (RPT), starting from computed tomographic (CT) examinations, is a promising technology in traumatology. It facilitates the planning and surgical results of complex fractures. Here, we used it ina complex bilateral acetabulum fracture for the assessment of the injury type and for improving knowledge of the fracture fragments. The patient was a forty-five year old male, with no accompanying fractures. The solid model allowed an accurate preoperative and intraoperative planning. The 3D printed model improved the understanding of anatomy of the fractures, in order to facilitate the surgical approach and the creation of dedicated pre-shaped plates. The useof the 3D model reduced surgical time, intraoperative soft tissues damage and blood loss as well as the risk of infections. Fluoroscoping imaging was also minimized. This case highlights the importance of 3D model in the management of complex fractures.
