Comparison of Magnetic Resonance Imaging and Stress Radiography in Diagnosing Chronic Anterior Talofibular Ligament Injury / 中国运动医学杂志

ABSTRACT

Objective To compare Magnetic Resonance Imaging(MRI) and stress radiography in diagnosing chronic anterior talofibular ligament (ATFL) injury.Methods Among 45 patients undergoing ankle arthroseopy between October 2016 and December 2016,39 patients were included in this study.The ankle arthroscopy was used as the gold standard for diagnosing the chronic ATFL injury.The sensitivity,speciality and accuary of MRI and stress radiography were calculated according to the arthroscopic findings.Results The ankle arthroscopy revealed ATFL injury in 30 cases and intact ATFL in 9 cases,while MRI results found ATFL injury in 28 cases and intact ATFL in 11 cases with thesensitivity,speciality and accuary of 90.0％,88.9％ and 89.7％ respectively.The stress radiography results revealed ATFL injury in 21 cases and intact ATFL in 18 cases,with the sensitivity,speciality and accuary of 63.3％,77.8％ and 66.7％.Conclusion MRI was more reliable in diagnosing chronic ATFL injury compared with the stress radiography.
