摘要
目的探讨前抽屉试验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患者40例,共42侧患踝;正常对照组40名,共80侧踝。拍摄前抽屉试验应力位片,测量距骨前移距离。结果患侧距骨前移距离(ATT)平均7.8mm,健侧5.4mm,对照组为6.1mm,患侧与健侧及对照组相比存在显著性差异(P<0.01),健侧与对照组相比,无显著性差异。患侧与健侧距骨前移距离差值穴△ATT雪平均2.4mm,对照组△ATT平均0.9mm(P<0.01)。结论前抽屉试验应力位片对于慢性外踝关节不稳诊断具有重要意义。ATT≥8mm,△ATT≥2mm可作为衡量踝关节不稳定的标准。
Objective To discuss the significance of anterior drawer stress radiograph in diagnosing of chronic instability of lateral ankle and bring forward the radiology diagnosis criteria.Methods The 40 patients with chronic instability of lateral ankle and 40 normal people （as controlled）were selected random.Bilateral ankles of each subject had been subjected to anterior drawer stress radiography.Anterior translation of talus （ATT）were measured.Results The average ATT of suffered ankles was 7.8mm,while the value of the opposite ankles was 5.4mm,the controlled group was 6.1mm.There was significant difference between the suffered ankles and normal ones （P〈0.01）.The average difference of ATT between the suffered ankles and uninjured ones was 2.4mm, compared with 0.9mm of controlled group （P〈0.01）. Conclusion Anterior drawer stress radiograph has significant meaning to the diagnosis of chronic ankle instability.ATT≥8mm,△ATT≥2mm on anterior drawer stress radiographs can be defined as the criteria to evaluate chronic ankle instability.
