摘　　要：目的评价磁共振在平片阴性的急性踝关节外伤中的临床应用价值。方法回顾分析21例X线平片阴性的急性踝关节外伤MRI图像,重点观察内外侧副韧带、骨与软骨,所有MRI检查均在48 h内完成。结果 15例MR发现踝关节周围骨挫伤,MR发现4例外侧副韧带,1例内侧副韧带断裂,5例关节软骨损伤,3例跟腱断裂。结论 MR在平片阴性的踝关节急性外伤的诊断中有重要价值。Objective To evaluate the value of MRI in acute ankle distortion without evidence of fracture. Methods The MRI appear-ances of 21 cases with acute trauma in the ankles were retrospectively analyzed,focusing on the presence or absence injuries of lateral collat-eral ligamentous complex,bone and osteochondral lesions,MRI was performed within 48 h of trauma. Results Bone bruise was observed in 15 patients. There were injuries of the lateral ligaments in 4 cases and the medial ligaments in 1 case. Injury of the osteochondral lesion was in 5 cases and Achilles tear was in 3 cases. Conclusion MRI have diagnostic value for acute ankle injury.
