Abstract Objective To compare X-ray, three-dimensional CT reconstruction and MRI in the diagnosis of complex tibial plateau fractures. Methods From January 2012 to December 2016, in People′s Hospital of Ruian City, 70 patients with complex tibial plateau fracturesours were select, all the patients were given the conventional X-ray examination, three-dimensional CT reconstruction and MRI, of diagnosis of joint damage of the surface subsidence and rest of the soft structure, diagnostic coincidence rate and classification accuracy were compared. Results Compared with X-ray and MRI, three-dimensional CT reconstruction had a higher diagnosis rate of articular surface subsidence, the differences were statistically significant (P < 0.05). Compared with X ray film and three-dimensional CT reconstruction, MRI had a higher diagnosis rate of the rest of the soft structure damage, the differences were statistically significant (P < 0.05). Compared with X-ray and MRI, three-dimensional CT reconstruction had higher diagnosis accordance rate and classification accuracy rate, the differences were statistically significant (P < 0.05). Conclusion Three-dimensional CT reconstruction can be intuitive and stereo display tibial fracture morphology, for the diagnosis of complex fractures of tibial plateau, helping found around the knee joint and joint of occult injury, improving the accuracy of diagnosis, it has important clinical effect.
