高频超声诊断急性踝内翻外侧副韧带损伤的临床价值

摘要

Objective To explore the effectiveness of application of thehigh-frequency ultrasonography in diagnosis of the acute ankle inversion sprain injury of the lateral collateral ligament.Methods Patients with clinical diagnosis of acute ankle inversion sprain were examined with the high frequency liner probe, and the appearances of lateral collateral ligament injury and avulsion fracture were emphatically observed. The ultrasonographic diagnosis of avulsion fracture was compared with X-Ray examination in all patients.Results Among 46 cases who were diagnosed of ATFL (Anterior taloifbular ligament) injuries with ultrasonography, 17 cases were Degree I injury, 20 cases were Degree II injury, 9 cases were Degree III injury, combined with 7 cases of CFL (Calcaneoifbular Ligament) contusion in Degree I injury and 5 cases in Degree II injury. Among 12 patients with ultrasound manifestations of tiny and avulsion fracture, 10 patients were positive and 2 were negative with X-Ray examination. Good consistency was seen between the results of ultrasound and X-Ray in diagnosis of fractures.Conclusion Thehigh-frequency ultrasonography demonstrates itself an imaging method with high-resolution and easy-to-operate features in evaluating soft tissue injuries and coexistent avulsion or tiny fractures for acute ankle sprain, which is worth wider clinical application.%目的：探讨高频超声诊断急性踝内翻外侧副韧带损伤的临床价值。方法对临床诊断为踝关节扭伤的患者，采用高频线阵探头探查其踝关节，重点观察外侧副韧带损伤情况及是否有撕脱性骨折。同时，对所有患者均行X线检查，将其中伴有撕脱性骨折的患者的超声诊断结果与X线检查结果进行比较。结果在46例经超声诊断为距腓前韧带损伤的患者中，17例为Ⅰ型损伤，20例为Ⅱ型损伤，9例为Ⅲ型损伤；合并跟腓韧带Ⅰ型损伤7例，Ⅱ型损伤5例；合并撕脱性或微小骨折12例，其中10例X线检查结果为阳性，2例为阴性。超声与X线对骨折的诊断结果具有良好的一致性。结论对于急性踝关节内翻扭伤所致的软组织损伤和可能合并的撕脱性或微小骨折，高频超声是一种分辨力高、操作简便的影像学检查方法，值得临床推广应用。
