【摘要】：目的:評估機械性踝關(guān)節(jié)不穩(wěn)患者中距腓前韌帶(anterior talofibular ligament,ATFL)和距腓后韌帶(posterior talofibular ligament,PTFL)之間的夾角,以提供一種診斷慢性ATFL損傷的新的間接診斷方法。方法:100名測試對象納入本研究,其中50名為機械性踝關(guān)節(jié)不穩(wěn)患者(A組),50名為因其他疾病至我院就診、非踝關(guān)節(jié)不穩(wěn)的患者(B組)。每名測試對象均在MRI橫斷面上測量ATFL與PTFL的夾角,并比較兩組患者的差異。結(jié)果:機械性踝關(guān)節(jié)不穩(wěn)組患者較對照人群ATFL和PTFL的夾角明顯增大(82.1°±8.0°vs 74.4°±5.9°,P0.01)。計算受試者工作特征曲線(receiver operating characteristiccurve,ROC)下面積為0.784,P0.01,有高度統(tǒng)計學(xué)意義,表明ATFL與PTFL的夾角對于慢性ATFL損傷的診斷有意義。利用其曲線坐標計算出當(dāng)ATFL與PTFL之間的夾角為79°時具有較高的靈敏度與特異度,分別為0.88和0.64。結(jié)論:機械性踝關(guān)節(jié)不穩(wěn)患者ATFL與PTFL的夾角明顯增大。當(dāng)ATFL與PTFL夾角大于79°時,慢性ATFL損傷的可能性升高。
[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 擄, 8.0 擄 vs 74.4 擄, 5.9 擄, 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 擄, 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 擄, the possibility of chronic ATFL injury is increased.
