Preoperative Simulation and Three-Dimensional Model for the Operative Treatment of Tibiofibular Diaphyseal Fracture: A Randomized Controlled Clinical Trial.

研究概要

Sixty patients with closed tibiofibular diaphyseal fractures were randomized to receive either preoperative simulation with a 3D-printed model (n=30) or conventional preoperative planning (n=30). The primary outcome of interest was operative time. Secondary outcomes included intraoperative blood loss, frequency of fluoroscopy, pain (VAS), and functional recovery (Johner-Wruhs scale). Outcomes were assessed preoperatively and at 6 and 12 months postoperatively. Overall, the results of the study revealed that the 3D printing group had significantly shorter operative time, less blood loss, and fewer fluoroscopy uses. However, functional outcomes were comparable between groups at one year. The findings suggest that 3D-printed models can improve surgical efficiency without compromising outcomes.
