肌骨超声对儿童急性踝关节扭伤韧带损伤分级及其他合并损伤的诊断价值
Diagnostic Value of Musculoskeletal Ultrasound in Grading Ligament Injuries and Detecting Other Combined Injuries in Children with Acute Ankle Sprain
摘要
Abstract
Objective To investigate the diagnostic value of musculoskeletal ultrasound(MSUS)in grading ligament injuries and detecting other combined injuries in children with acute ankle sprain.Methods A total of 100 children with acute ankle sprain who were treated in our hospital from April 2023 to August 2025 were retrospectively selected as the research objects.All children underwent both MSUS and magnetic resonance imaging(MRI)examinations.Taking MRI findings as the diagnostic standard,the diagnostic performance of MSUS in grading ligament injuries and identifying other combined injuries in children with acute ankle sprain was evaluated.Results All 100 children had anterior talofibular ligament(ATFL)injury.MRI showed 46 cases of grade Ⅰ injury,51 cases of grade Ⅱ injury,and 3 cases of grade Ⅲ injury;MSUS showed 42 cases of grade Ⅰ injury,56 cases of grade Ⅱ injury,and 2 cases of grade Ⅲ injury.Consistency analysis revealed good agreement between MSUS and MRI in grading ATFL injury(Kappa=0.712).Receiver operating characteristic(ROC)curve analysis showed that MSUS had a sensitivity of 94.44%,specificity of 84.78%,accuracy of 90.00%,and an area under the curve(AUC)of 0.930(95%CI:0.839～0.930,P<0.001)for diagnosing grade≥Ⅱ ATFL injury.For joint effusion,tendon injury,epiphyseal injury,and avulsion fracture of the lateral malleolar epiphysis,the detection rates were 100.00%,30.00%,75.00%,and 48.00%by MRI,and 98.00%,26.00%,68.00%,and 60.00%by MSUS,respectively,with no statistically significant difference between the two methods(P>0.05).Conclusions MSUS can accurately assess the severity of ATFL injury in children with acute ankle sprain,with good consistency with MRI results in injury grading.Meanwhile,MSUS can effectively detect accompanying lesions such as joint effusion,tendon injury,epiphyseal injury,and avulsion fracture of the lateral malleolar epiphysis,with no significant statistical difference compared to MRI findings.Therefore,MSUS can be used as an effective diagnostic tool for acute ankle sprain in children.关键词
