Among them, the changes of thickness, echo, continuity, tension of anterior talofibular ligament, passive varus ligament of plantar flexion, changes of joint space, and energy Doppler during compression were mainly observed. Results: 16 cases of type III acute injury of anterior talofibular ligament, 19 cases of type II acute injury of anterior talofibular ligament and 33 cases of type I acute injury of anterior talofibular ligament were diagnosed by high-frequency two-dimensional ultrasound, among which 5 cases of type III acute injury were misdiagnosed as type II injury, 13 cases of type III acute injury of anterior talofibular ligament were diagnosed by energy Doppler under pressure, 20 cases of type III acute injury of anterior talofibular ligament, 15 cases of type II acute injury of anterior talofibular ligament and 33 cases of type I acute injury of anterior talofibular ligament were diagnosed by high-frequency two-dimensional ultrasound combined with energy Doppler under pressure, among which 1 case of type III acute injury was misdiagnosed as type II injury. Conclusion: High frequency ultrasound can diagnose and classify the acute injury of anterior talofibular ligament. High frequency ultrasound combined with pressurized energy Doppler can improve the diagnostic efficiency of type III acute injury of anterior talofibular ligament.展开更多
