Original ResearchRepair of the Acute Deltoid Ligament Complex Rupture Associated With Ankle Fractures: A Multicenter Clinical Study
Section snippets
Setting and Location of Data Collection
The institutional review board approved the present multicenter, retrospective, trial involving 4 cities (Shanghai, Dalian, Wuhan, and Hangzhou) in the east, north, and west of China separately. From January 2006 to December 2011, 1533 operatively treated ankle fractures were identified. Of these, a ruptured deltoid ligament was identified in 131. All the authors collected the data from the 4 centers, and 2 of us (Z.M.Z. and Y.G.R.) completed the data analysis.

Results
Most of the patients were male and had sustained their ankle injury in falls, traffic accidents, collision sports, or bicycling or motorcycling accidents (Table). No significant differences were found in the demographic features or injury patterns between the 2 groups.
A total of 106 patients (81%) were followed up for an average of 27 (range 12 to 72) months. The mean interval to fracture healing was 14.5 (range 9 to 16) weeks according to the radiographic findings. The initial reduction of the
Biomechanical Characters of Deltoid Ligament
The deltoid ligament is the primary restraint to posterior translation of the talar, with a relative contribution ranging from 50% to 80%. The contribution of the deltoid ligament was significantly greater in plantar flexion than in dorsiflexion (7). The deltoid ligament controls external and internal rotation of the talus, in conjunction with the anterior talofibular ligament. Rupture of the deep deltoid ligament will lead to increased external rotation. The studies by Rasmussen et al (8)

2022, Foot and Ankle SurgeryCitation Excerpt :Radiographs were accessed through the Picture Archiving Communication System (PACS). The deep deltoid ligament was assumed to be ruptured if the MCS was ≥ 5 mm [2,4,15,18] on the preoperative mortise view. Patient demographics, mechanism of injury, fracture pattern, syndesmotic fixation, and performance of deltoid ligament repair were recorded.
