The digital simulation of fracture reduction and fixation of complicated acetabular fractures
Objective To investigate the fracture reduction and implant simulation of complicated acetabular fractures using digital medical technologies. Methods CT image of one case of complicated acetabular fractures was obtained and imported into software Mimics. Geometry models of pelvis were three-dimensionally (3D) reconstructed. Fracture Reduction and implant simulation were performed in software Geomagic, which served as a surgical guidance. The CT images of the same patient were obtained again 3 months after the operation. The postoperative models were also reconstructed for comparison and evaluation. Results According to the Tile classification, the case was type C2-3. By using Mimics software, the 3D model accurately reflected the structure of pelvis with complicated acetabular fractures. With bone fragments being moved and rotated in Geomagic, fracture reduction and implant simulation were performed. The post-operation effect was good after following-up. The positions of plates and screws in pre- and post-operation stages were very close. Conclusions The digital medical technologies are very useful for fracture reduction and implant simulation, which can improve the accuracy of the surgery.
