The objective of this study was to elucidate the relationship between lateral collateral ligamentous injuries of the ankle (ankle sprain) and bone bruise (trabecular trauma) of the talus and/or malleoli in the patients with twisting injuries of the ankle.
Magnetic resonance studies of the ankle were retrospectively reviewed, focusing on the presence or absence of lateral collateral ligamentous injuries and the location of bone bruise in the talus and/or malleoli.
Thirty-five patients with acute twisting injuries of the ankle were studied.
Four patterns of bone bruise were found in 14 patients: (1) bone bruise in the talar dome equivalent to osteochondral fracture in two patients, (2) bone bruise in the posteromedial aspect of the talus and the medial malleolus singly or in combination in four, (3) bone bruise in the anteromedial aspect of the talus in six, and (4) bone bruise with a combination of the second and third patterns in two. The second pattern was associated with tear of the anterior talofibular (ATAF) ligament in all patients and injury of the calcaneofibular (CF) ligament in one out of four. The third and fourth patterns were associated with tears of both ATAF and CF ligaments in all patients. The identification of bone bruise was of value in indicating lateral collateral ligamentous injuries.
本研究的目的是阐明踝关节扭伤患者中，踝关节外侧副韧带损伤与距骨和/或踝关节骨折（小梁损伤）之间的关系。
对踝关节的磁共振研究进行回顾性分析，重点关注外侧副韧带损伤的有无以及距骨和/或踝关节骨折的位置。
对35例急性踝关节扭伤患者进行了研究。
14例患者发现了四种骨折模式：（1）两名患者距骨穹窿部骨折相当于骨软骨骨折；（2）四名患者距骨后内侧和内踝单独或合并出现骨折；（3）六名患者距骨前内侧出现骨折；（4）两名患者出现第二种和第三种模式合并的骨折。第二种模式在所有患者中均与距腓前韧带（ATAF）撕裂相关，四名患者中有一名同时合并跟腓韧带（CF）损伤。第三种和第四种模式在所有患者中均与ATAF和CF韧带撕裂相关。骨折的识别对于提示外侧副韧带损伤具有重要价值。
