The purpose of the present study was to clarify the usefulness of the oblique axial scan parallel to the course of the anterior talofibular ligament in magnetic resonance imaging of the anterior talofibular ligament in patients with chronic ankle instability. We evaluated this anterior talofibular ligament view and routine axial magnetic resonance imaging planes of 115 ankles. We diagnosed the grade of the anterior talofibular ligament injury and confirmed full-length views of the anterior talofibular ligament. Associated lesions were also checked. The subjective diagnostic convenience of associated problems was determined. The full-length view of the anterior talofibular ligament was checked in 85 (73.9%) patients in the routine axial view and 112 (97.4%) patients in the anterior talofibular ligament view. The grade of injury increased in the anterior talofibular ligament view in 26 (22.6%) patients compared with the routine axial view. There were 64 associated injuries. The anterior inferior tibiofibular ligament, posterior inferior tibiofibular ligament, and posterior tibialis tendinitis were more easily diagnosed on the routine axial view than on the anterior talofibular ligament view. An additional anterior talofibular ligament view is useful in the evaluation of the anterior talofibular ligament in patients with chronic ankle instability.
本研究的目的是阐明在慢性踝关节不稳患者的距腓前韧带磁共振成像中，与距腓前韧带走行平行的斜轴位扫描的实用性。我们评估了115个踝关节的这种距腓前韧带视图和常规轴位磁共振成像平面。我们诊断距腓前韧带损伤的分级，并确认距腓前韧带的全长视图。还检查了相关病变。确定了相关问题的主观诊断便利性。在常规轴位视图中，85例（73.9%）患者的距腓前韧带获得了全长视图，在距腓前韧带视图中，112例（97.4%）患者获得了全长视图。与常规轴位视图相比，在距腓前韧带视图中，26例（22.6%）患者的损伤分级增加。共有64处相关损伤。胫腓前下韧带、胫腓后下韧带和胫后肌腱炎在常规轴位视图上比在距腓前韧带视图上更容易诊断。额外的距腓前韧带视图在评估慢性踝关节不稳患者的距腓前韧带方面是有用的。
