Objective To evaluate the digital design of acetabular fractures and the feasibility of the implementation, then using the 3D printing technique to verify the results. Methods Fifty-two patients with acetabular fractures were enrolled in this study. Data of lamellar CT scanning were imported into Mimics14.0 software for 3D anatomical modeling and virtual fracture reduction. Then the default embedded steel plate location was optimized , the screw path evaluated，and the screw length measured. 3D printing technique was used to print the bone. Plates were bended based on the printing bones. Internal fixation implants were simulated based on all the printed bones and bended plates. Finally, the real operation was compared with virtual preoperative design in terms of the fixation position of plates, the direction and the length of screws. Results In the study, 61 plates and 424 screws were planted. The position of plates and the direction of screws were in high accordance with the digital design. The length of screws are compared with Paired-samples t Test and P=0.325. Conclusion Firstly, the combination of the digital design and 3D printing technique have a good application in the bending of the plates and surgery simulation before operation. The real operation is quite consistent with the simulated results. Secondly, plate bending before the real operation has a certain value in the guidance of fracture reduction.
