【摘要】：目的探讨应力位片在慢性外踝关节不稳定诊断中的意义,提出影像学的定量诊断方法。方法随机选择慢性外踝关节不稳的陆军士兵40人共42侧患踝,正常对照组40人共80侧踝。拍摄前抽屉试验侧位片及内翻应力正位片,分别测量距骨前移距离(ATT)及距骨斜角(TT)。结果患侧ATT平均7.8mm,TT平均9.1°,而健侧分别为5.4mm及5.4°,对照组为6.1mm及4.9°,患侧与健侧及对照组比较均有显著性差异(P0.01),健侧与对照组比较差异无显著性。患侧与健侧距骨前移距离差值(△ATT)平均2.4mm,距骨斜角差值(△TT)平均3.7°,而对照组分别为0.9mm及1.1°,与慢性外踝关节不稳的40例比较差异显著(P0.01)。118例正常踝关节ATT、TT的P95分别为8mm及9°。结论前抽屉试验侧位片及内翻应力正位片对于慢性外踝不稳诊断具有重要意义。前抽屉试验侧位片中ATT≥8mm、△ATT≥2mm,内翻应力正位片中TT≥9°、△ATT≥3°可作为衡量踝关节不稳定的标准。
[Abstract]:Objective to explore the significance of stress position film in the diagnosis of chronic lateral ankle instability and to put forward a quantitative imaging diagnostic method. Methods Forty army soldiers with chronic lateral ankle instability were randomly selected from 42 affected ankles. In the control group, 80 malleolus were obtained from 40 normal subjects. The lateral films and inverted stress films were taken in the anterior drawer test. Results the average ATT of the affected side was 9.1 掳, while that of the healthy side was 5.4 掳and 6.1mm and 4.9 掳, respectively. There was significant difference between the affected side and the healthy side and the control group (P 0.01). There was a significant difference between the affected side and the healthy side and the control group (P < 0.01). There was no significant difference between the two sides. The average ATT was 2.4 mm, and the average gradient of talus was 3.7 掳, compared with 0.9 mm and 1.1 掳in the control group. There was a significant difference between the patients with chronic lateral ankle instability (40 cases) and the patients with chronic lateral ankle instability (P 0.01). 118 cases were positive. The P95 of ATTTTTTT in normal ankle joint is 8mm and 9 掳respectively. Conclusion it is important to diagnose chronic lateral malleolus instability by anterior drawer test lateral film and varus stress positive film. The ATT 鈮，
