Treatment of supination external rotation type IV (SER-IV) ankle injuries has focused on reduction and fixation of the fibula and syndesmosis (ORIF), not repair of the deltoid ligament.
Twenty-one ankles were analyzed with a motion capture system. Uninjured ankles were stressed and compared to ankles with SER-IV injuries, then with ORIF, and finally ORIF and deltoid repair.
After deltoid ligament repair, talar coronal and axial rotation normalized to the uninjured state and were significantly reduced compared to ORIF alone.
Deltoid ligament repair after an SER-IV ankle injury can help directly reduce and stabilize the tibiotalar joint.
旋后外旋IV型（SER-IV）踝关节损伤的治疗重点在于腓骨和下胫腓联合的复位与固定（切开复位内固定术，ORIF），而非三角韧带的修复。
使用运动捕捉系统对21个踝关节进行分析。对未受伤的踝关节施加应力，并与患有SER-IV损伤的踝关节进行比较，然后与接受ORIF治疗的踝关节进行比较，最后与接受ORIF和三角韧带修复的踝关节进行比较。
三角韧带修复后，距骨的冠状面和轴向旋转恢复至未受伤状态，与单纯ORIF相比明显减少。
SER-IV踝关节损伤后进行三角韧带修复有助于直接复位并稳定胫距关节。
