Abstract: This article explored the application of MRI in the preoperative examination and postoperative management of sports-induced ankle fractures. 98 patients with ankle fractures caused by sports were selected as research objects, and used MRI to scan the ankle joints in different body positions, and then scored the ankle function according to the AOFAS scoring system. The results showed that MRI multi-planar, multi-sequence scan can clearly show the anatomical structure around the ankle ligament, significantly improve the accuracy of clinical diagnosis. The single factors related to ankle fractures include: diabetes, smoking, trauma, violence, whether the syndesmosis of the tibia and fibula was fixed during the operation, fracture reduction, fracture classification. Multi-factor analysis of ankle fracture functional recovery was related to fracture reduction and fracture classification. In short, MRI could significantly improve the accuracy of preoperative examination of sports-induced ankle fractures, and in postoperative management, the classification of ankle fractures and the reduction of fractures need to be fully evaluated.

Key words: magnetic resonance imaging(MRI), ankle fracture, preoperative examination, postoperative management
