A comparative study of high frequency ultrasound and magnetic resonance imaging in the diagnosis of acute anterior talofibular ligament injury during military training
Objective To explore the diagnostic value of high-frequency ultrasound for acute anterior talofibular ligament injury in military training.Methods The study method was prospective analysis,and 90 patients with unilateral ankle sprain were selected.The continuity,thickness,texture,tension,and surrounding soft tissue of the bilateral anterior talofibular ligament were examined by high-frequency ultrasound,and the injury types were classified.Then the features were recorded by MRI.The result of ultrasound and MRI were compared and analyzed statistically.Results 80 cases of anterior talofibular ligament injury were diagnosed by ultrasound and MRI.There were 56 cases of grade I injury(contusion),17 cases of grade Ⅱ injury(incompletely torn),and 7 cases of grade Ⅲ injury(completely torn)of the anterior talofibular ligament diagnosed by ultrasound.MRI diagnosis of grade Ⅰinjury in 60 cases,grade Ⅱ injury in 13 cases,and grade Ⅲ injury in 7 cases,SPSS software was used for consistency analysis,and the consistency test result showed that the consistency coefficient between high-frequency ultrasound and MRI was Kappa=0.884(P<0.001),and there were significant differences between the two in grade Ⅰ injury and grade Ⅱ injury and grade Ⅲ injury had no significant difference(χ2=0.502,0.656,0.000,P>0.05).Taking MRI as the gold standard,the area under the curve(AUC)of high-frequency ultrasound in the diagnosis of the anterior talofibular ligament was 0.944.There were no significant differences between ultrasound and MRI measurements of peripheral effusion,tension,and peripheral soft tissue(χ2=0.102,0.129,0.592,P>0.05).Ultrasound was superior to MRI in the diagnosis of 16 cases of bone avulsion(χ2=17.778,P<0.001).The thickness of the anterior fibular ligament was(3.17±0.58)mm measured by ultrasound and(3.33±0.57)mm measured by MRI,with statistical significance(P<0.05).Conclusion High-frequency ultrasound is accurate,rapid,and simple in the diagnosis of anterior talofibular ligament injury,which has high clinical application value.
