Abstract 【Objective】To investigate the diagnostic and prognostic value of magnetic resonance imaging (MRI) and multi-slice spiral CT (MSCT) 3D examination in different body positions in the diagnosis and classification of complex ankle joint injuries. 【Methods】The clinical data of 215 patients with complex ankle injuries admitted to the hospital from April 2021 to March 2023 were retrospectively analyzed. All patients received conventional position MSCT 3D examination, optimized position MSCT 3D examination and MRI examination. Taking pathological diagnosis as the gold standard, the diagnostic value of MRI and different body positions' MSCT 3D in complex ankle joint injury, classification, type of cartilage injury and prognosis were analyzed. 【Results】Of 215 cases of complex ankle injuries, 46 cases of pronation-pronation type (PE), 38 cases of supination-external pronation type (SE), 49 cases of supination-adduction type (SA), 32 cases of vertical compression type (VC), 50 cases of pronation-abduction type (PA). There were 40 cases of stage Ⅰ, 59 cases of stage Ⅱ, 64 cases of stage Ⅲ, and 52 cases of stage Ⅳ. Anatomical reduction occurred in 186 cases and non-anatomical reduction in 29 cases. The diagnostic accuracy of optimized postural MSCT 3D and VC was higher than that of conventional position MSCT 3D and MRI (P<0.05), and the diagnostic rate of MSCT 3D in conventional position was higher than that of MRI (P<0.05). There was no difference in the accuracy of PE, SE, SA and PA among the three methods in the diagnosis of complex ankle injury classification (P>0.05). The accuracy of MRI in diagnosing anatomic reduction of different types of cartilage injury and complex ankle injury was higher than that of MSCT 3D in optimal position and MSCT 3D in conventional position (P<0.05), and the diagnostic accuracy of MSCT 3D in optimal position was higher than that of conventional position (P<0.05). 【Conclusion】Optimized postural MSCT 3D examination is more valuable than MRI and conventional postural MSCT 3D examination in diagnosing complex ankle injuries. The value of MRI in the diagnosis of cartilage injury type and prognosis is higher than that of MSCT 3D in different positions.
