Our goal was to evaluate the visibility and incidence of traumatic abnormalities of the sinus tarsi in patients with acute ankle sprain injuries and compare these findings with the extent of lateral ankle ligament injuries on MRI.
Sixty athletically active patients (aged 18-45 years) with recent inversion trauma (< or = 7 days) underwent MRI. Replacement of fat tissue in the sinus tarsi was recorded. Inter/intraobserver agreement was calculated (kappa-statistics). Injuries of the three lateral ligaments, evaluated by MRI, were graded according to partial (1 point) or complete (2 points) tears for each of three lateral ligaments (together 0-6 points) and were compared with sinus tarsi abnormalities.
In 26 patients (43%), replacement of sinus tarsi fat tissue was depicted by MRI. Inter/intraobserver agreement for MR changes of the sinus tarsi was good to moderate (kappa = 0.675/0.584). Grade of lateral ankle ligament injury showed a statistically significant difference (p = 0.033) between the two sinus tarsi groups (normal/abnormal).
Acute ankle sprain injuries, evaluated by MRI, are associated with acute abnormalities of the sinus tarsi in 43% of patients and correlate with the extent of lateral ankle ligament tears.
我们的目标是评估急性踝关节扭伤患者距骨窦创伤性异常的可视性和发生率，并将这些结果与MRI上外侧踝关节韧带损伤的程度进行比较。
60名近期发生内翻创伤（≤7天）、年龄在18 - 45岁的活跃运动员接受了MRI检查。记录距骨窦内脂肪组织的替代情况。计算观察者间/观察者内一致性（kappa统计量）。通过MRI评估的三条外侧韧带损伤，根据每条外侧韧带的部分（1分）或完全（2分）撕裂进行分级（总分0 - 6分），并与距骨窦异常情况进行比较。
26例患者（43%）的MRI显示距骨窦脂肪组织被替代。距骨窦MRI变化的观察者间/观察者内一致性为中等至良好（kappa = 0.675/0.584）。两组距骨窦（正常/异常）之间的外侧踝关节韧带损伤分级存在统计学显著差异（p = 0.033）。
通过MRI评估，43%的急性踝关节扭伤患者伴有距骨窦急性异常，且与外侧踝关节韧带撕裂程度相关。
