Transverse ligament and posterior inferior tibiofibular ligament injuries have not been investigated till date because these are difficult to evaluate using standard magnetic resonance imaging. This study aimed to investigate the prevalence of transverse ligament and posterior inferior tibiofibular ligament injuries in syndesmosis-injured ankles using oblique axial magnetic resonance imaging.
The patients who were diagnosed with syndesmosis injury using magnetic resonance imaging (MRI) within 7 days of the trauma were included. Patients with concomitant fractures were excluded. A total of 34 patients (1 woman and 33 men) with an average age of 22 years (range, 14-64 years) were included. The anterior inferior tibiofibular, interosseous, transverse, and posterior inferior tibiofibular ligaments were classified as intact, partial tear, or complete tear using usual axial and oblique axial MRIs.
There were 8 (23.5%) ankles with an intact, 21 (61.8%) ankles with a partially torn, and 5 (14.7%) ankles with a complete tear of transverse ligament. There were 20 (58.8%) ankles with an intact, 12 (35.3%) ankles with a partially torn, and 2 (5.9%) ankles with a complete tear of posterior inferior tibiofibular ligament. Overall, 50% of the transverse ligament injuries occurred without posterior inferior tibiofibular ligament involvement.
The oblique axial magnetic resonance imaging scan revealed that the prevalence of transverse ligament and posterior inferior tibiofibular ligament injuries in syndesmosis-injured ankles were 76.5 and 41.2%, respectively.
由于横韧带和下胫腓后韧带损伤很难通过标准磁共振成像进行评估，因此至今尚未对此进行研究。本研究旨在通过斜矢状面磁共振成像来研究踝关节下胫腓联合损伤中横韧带和下胫腓后韧带损伤的发生率。
本研究纳入了在创伤后 7 天内通过磁共振成像（MRI）诊断为下胫腓联合损伤的患者。排除伴有骨折的患者。共纳入 34 例患者（1 名女性和 33 名男性），平均年龄为 22 岁（14-64 岁）。使用常规矢状面和斜矢状面 MRI 将前下胫腓、骨间、横韧带和下胫腓后韧带分为完整、部分撕裂或完全撕裂。
8 例（23.5%）踝关节横韧带完整，21 例（61.8%）踝关节横韧带部分撕裂，5 例（14.7%）踝关节横韧带完全撕裂。20 例（58.8%）踝关节后下胫腓韧带完整，12 例（35.3%）踝关节后下胫腓韧带部分撕裂，2 例（5.9%）踝关节后下胫腓韧带完全撕裂。总的来说，50%的横韧带损伤没有后下胫腓韧带的参与。
斜矢状面磁共振成像显示，下胫腓联合损伤踝关节中横韧带和后下胫腓韧带损伤的发生率分别为 76.5%和 41.2%。
