【摘要】：目的:评估机械性踝关节不稳患者中距腓前韧带(anterior talofibular ligament,ATFL)和距腓后韧带(posterior talofibular ligament,PTFL)之间的夹角,以提供一种诊断慢性ATFL损伤的新的间接诊断方法。方法:100名测试对象纳入本研究,其中50名为机械性踝关节不稳患者(A组),50名为因其他疾病至我院就诊、非踝关节不稳的患者(B组)。每名测试对象均在MRI横断面上测量ATFL与PTFL的夹角,并比较两组患者的差异。结果:机械性踝关节不稳组患者较对照人群ATFL和PTFL的夹角明显增大(82.1°±8.0°vs 74.4°±5.9°,P0.01)。计算受试者工作特征曲线(receiver operating characteristiccurve,ROC)下面积为0.784,P0.01,有高度统计学意义,表明ATFL与PTFL的夹角对于慢性ATFL损伤的诊断有意义。利用其曲线坐标计算出当ATFL与PTFL之间的夹角为79°时具有较高的灵敏度与特异度,分别为0.88和0.64。结论:机械性踝关节不稳患者ATFL与PTFL的夹角明显增大。当ATFL与PTFL夹角大于79°时,慢性ATFL损伤的可能性升高。
[Abstract]:Objective: To evaluate the angle between anterior and posterior ligament (ATFL) and postural ligament (PTFL) in patients with mechanical ankle instability, in order to provide a new indirect diagnostic method for the diagnosis of chronic ATFL injury. Methods:100 patients with mechanical ankle instability (group A) and 50 patients with unstable ankle instability (group B) were included in the study. The included angle between the ATFL and the PTFL was measured on the MRI cross-section for each test subject and the difference between the two groups was compared. Results: The included angle of ATFL and PTFL in the patients with mechanical ankle instability increased significantly (82.1 掳, 8.0 掳 vs 74.4 掳, 5.9 掳, P 0.01). The area of the working characteristic curve (ROC) of the subject was 0.784, P 0.01, and there was a high statistical significance, indicating that the included angle between the ATFL and the PFL was of great significance to the diagnosis of the chronic ATFL injury. When the included angle between the ATFL and the PTFL was 79 掳, the sensitivity and specificity were calculated with the curve coordinates of 0.88 and 0.64, respectively. Conclusion: The angle of ATFL and PTFL in patients with mechanical ankle instability increased significantly. When the included angle of ATFL and PTFL is greater than 79 掳, the possibility of chronic ATFL injury is increased.
