@@@@BACKGROUND: The hip fractures are difficult to treat because of its complexity. Clinicians select appropriate treatment options and surgical approaches according to imaging studies, which are difficult to accurately determine the spatial three-dimensional relationship. @@@@OBJECTIVE: To study the feasible and clinical value of computer-assisted preoperative design for hip fractures based on 64-slice spiral CT scanning data. @@@@METHODS: CT data in .dicom format from the patients with hip fractures were imported into Mimics. In segmentation process, the three-dimensional model of fracture was built to perform simulated reduction. The reduced model in .stl format was transferred into Imageware 12.0 to determine an appropriate dynamic hip screw in a suitable place and fixed with screw. And then using rapid prototyping, the entity and navigation template were formed. @@@@RESULTS AND CONCLUSION: The three-dimensional reconstructed visualization model could reflect the features of fractures, and the direction and degree of fracture displacement. And the fracture models could be rotated in any direction and space for observation which could simulate the internal fixation surgery. Preoperative computer-assisted virtual reality surgery can help to make a reasonable individualized surgical option, which has good clinical value.
