OBJECTIVE
To evaluate the frequency of deltoid ligament injury in bimalleolar supination-external rotation type fractures and whether there is a correlation between the size of the fractured medial malleolus and deltoid ligament injury
METHODS
Twenty six consecutive patients underwent magnetic resonance exams after clinical and radiographic diagnosis of bimalleolar supination-external rotation type ankle fractures
RESULTS
Thirteen patients (50%) presented deltoid ligament injury associated to bimalleolar ankle fracture. Partial injury was present in seven (26.9%) patients and total injury in six (23.1%). Regarding medial fragment size, the average was 2.88 cm in the absence of deltoid ligament injury. Partial injuries presented 1.93 cm and total 2.1 cm on average
CONCLUSION
Deltoid ligament injury was present in 50% of bimalleolar ankle fractures. Smaller medial malleolus fragments, especially concerning the anterior colliculus, presented greater association with partial deltoid ligament injuries.
目的
评估双踝旋后-外旋型骨折中三角韧带损伤的发生率，以及内踝骨折大小与三角韧带损伤之间是否存在相关性。
方法
连续26例患者在临床及影像学诊断为双踝旋后-外旋型踝关节骨折后接受磁共振检查。
结果
13例（50%）患者出现与双踝骨折相关的三角韧带损伤。7例（26.9%）为部分损伤，6例（23.1%）为完全损伤。在内侧骨折块大小方面，无三角韧带损伤者平均为2.88 cm。部分损伤者平均为1.93 cm，完全损伤者平均为2.1 cm。
结论
50%的双踝踝关节骨折存在三角韧带损伤。较小的内踝骨折块，尤其是前丘部骨折块，与三角韧带部分损伤的相关性更大。
