Abstract：Objective: To compare the value of 64 slice spiral CT three dimensional reconstruction in Tile classification of pelvic fractures. Methods: From January 2017 to June 2018, 51 patients with pelvic fractures were selected as subjects. All patients were examined by X-ray, two-dimensional CT and CT three-dimensional reconstruction. The diagnostic results of the three methods were compared according to the gold standard of surgical diagnosis. Results: According to the gold standard, there were 9 cases of Tile A type, 30 cases of B type and 12 cases of C type in 51 patients. The diagnostic accuracy of three-dimensional CT reconstruction for Tile classification was 100.00%, significantly higher than that of X-ray scanning (74.51%) and two-dimensional CT (88.34%), the difference was statistically significant (P<0.05). Both X-ray scan and two-dimensional CT were in good agreement with the gold standard (к = 0.696, 0.859, P<0.001). CT three-dimensional reconstruction is fully consistent with the gold standard test results. Conclusion: CT three-dimensional reconstruction is superior to two-dimensional CT and X-ray scan in judging Tile classification of pelvic fracture.
