The Clinical Application Of MRI In The Evaluation Of Lateralankle Ligament Injury

Objective:To explore the clinical application of MRI in the evaluation of lateral ankle ligament injury.Materials and Methods:Selection in June 2019-January 2021 jilin university fellowship between China and Japan’s hospitals clinical diagnosis of ankle talofibular ligament damage before and only for the conservative treatment of 61 patients,the routine MRI sequences of ankle scanned,by two high qualification doctor diagnose,according to the damage degree Ⅰ ligament injury--Ⅲ level,respectively by MRI imaging score,The scoring factors included the grade of ligament injury,ligament thickness,peripheral effusion,synovitis,diffuse hypersignal of ligament,morphological flexion and other factors.Then,the imaging score was compared with the AOFAS score of ankle joint function obtained by the patients 1-1.5 years later to observe whether the two were correlated.The pain relief and stability time of patients were collected,and the difference between the mild and severe anterior talofibular ligament injury groups was compared.Patients were divided into groups according to BMI index or age,and the differences in clinical AOFAS score,pain stabilization time and pain relief time among all groups were compared.Result:There was a correlation between MRI image score and AOFAS score（P<0.05）.There were statistically significant differences in AOFAS score,pain stabilization time and pain relief time between mild and moderate group and severe group（P<0.05）.At the same time,there were statistically significant differences in AOFAS score and pain relief time between the young group and the elderly group（P<0.05）,but there were no statistically significant differences in pain stabilization time between the young group and the elderly group（P>0.05）.The AOFAS score of patients with mild,normal and partial reorganization was significantly different from that of obese group（P<0.05）.Conclusion:1.MRI findings of patients with anterior talofibular ligament injury during acute ankle sprain can predict the prognosis of ankle injury,and the imaging findings are correlated with AOFAS score,suggesting that severe ligament injury is an important factor affecting long-term prognosis.2.The severity of anterior talofibular ligament injury was statistically different from the patient’s pain relief time and pain stabilization time,indicating the prognosis of the patient.3.Age and BMI are important factors affecting the prognosis of patients,and the combination of patient’s MRI findings can provide patients’ prognosis information for the clinic and help the formulation of treatment plans.
