目的 比较多层螺旋CT三维重建 与X线在急性踝关节损伤诊断中的应用价 值。方法 2016年6月-2018年6月我院收治 的86例急性踝关节损伤患者，均于伤后 24h内接受多层螺旋CT三维重建与X线检 查，比较两种检查方法的诊断准确率。结 果 86例急性踝关节损伤患者中，三角韧 带拉伤12例，下胫腓分离18例，骨间膜损 伤12例，外踝腓距前韧带损伤19例，下胫 腓前韧带损伤25例；多层螺旋CT三维重 建检查诊断准确率93.02%(80/86)显著高 于X线检查诊断75.58%(65/86)，差异有统 计学意义(χ2 =9.885，P<0.05)。结论 多 层螺旋CT三维重建可从多方位、多角度清 晰显示急性踝关节损伤类型，避免影像重 叠，应用价值明显高于X线诊断，可为患 者临床治疗方案的制定提供重要依据。

Objective To compare the value of multi-slice spiral CT three-dimensional reconstruction and X-ray in the diagnosis of acute ankle injury. Methods A total of 86 patients with acute ankle injury who were admitted to the hospital from June 2016 to June 2018 were selected. All patients underwent multi-slice spiral CT three-dimensional reconstruction and X-ray examination within 24 hours after injury. The diagnostic accuracy was compared between the two methods. Results Of the 86 patients with acute ankle injury, 12 cases were deltoid ligament injury, 18 cases were inferior tibiofibular syndesmotic disruption, 12 cases were interosseous membrane injury, 19cases were anterior ligament injury of lateral malleolus fibulae, and 25 cases were anterior inferior tibiofibular ligament injury. The diagnostic accuracy of multi-slicespiral CT threedimensional reconstruction [93.02% (80/86)] was significantly higher than that of X-ray examination [75.58% (65/86)] (χ2 =9.885, P<0.05). Conclusion Multi-slice spiral CT three-dimensional reconstruction can clearly show the type of acute ankle injury from multiple directions and multiple angles, avoiding image overlap. The application value is significantly higher than X-ray and it can provide important basis for the development of clinical treatment plan.
