Comparative Study
Comparison of screw fixation with elastic fixation methods in the treatment of syndesmosis injuries in ankle fractures.
17 patients with ankle syndesmosic injury were treated with a 4.5mm single cortical screw fixation (passage of screw 4 cortices) and 15 patients were treated with single-level elastic fixation material. All patients were evaluated according to the AOFAS ankle and posterior foot scale at the third, sixth and twelfth months after the fixation. The ankle range of movement was recorded together with the healthy side. ⋯ The range of dorsiflexion and plantar flexion motion of the elastic fixation group at the 6th and 12th months were significantly better compared to the screw fixation group (p<0.01). Elastic fixation is as functional as screw fixation in the treatment of ankle syndesmosis injuries. The unnecessary need of a second surgical intervention for removal of the fixation material is another advantageous aspect of this method of fixation.

Comparative Study
Biomechanical comparison of syndesmotic injury fixation methods using a cadaveric model.
There is growing interest in suture-button devices for syndesmosis injury, which are intended to offer less rigid fixation than screw fixation. ⋯ Suture-button devices provided torsional strength below that of screw fixation. However, all devices may provide failure torques well above 20 Nm, exceeding likely torques applied in casts during healing.(1,2,4) CLINICAL RELEVANCE: Suture-button devices appear to have provided adequate fixation strength for syndesmosis injuries.
