Figure 2

Intraoperative operations. (a, b) Medial and lateral incisions. (c) The anchor was placed in the talus at the talar insertion of the deep deltoid ligament. (d) Bone fragments in the distal tibiofibular joint were cleared, and the reduction was performed through a small anterior incision. (e) Intraoperative fluoroscopy showed an unsatisfactory medial mortise after fixation of the distal tibiofibular joint and repair of the deep deltoid ligament. (f) Intraoperative fluoroscopy revealed satisfactory medial mortise after the additional repair of the superficial deltoid ligament.
