Syndesmotic injuries involve disruption of the distal tibiofibular ligament complex and may occur as isolated high ankle sprains or in association with ankle fractures. The key clinical distinction is between stable and unstable injuries, using clinical examination, radiographs, advanced imaging, and dynamic or intra-operative testing when required. Accurate restoration of fibular length, rotation, and position within the tibial incisura is fundamental before syndesmotic fixation. Unstable injuries can be stabilized using traditional syndesmotic screws or dynamic suture-button devices, with each technique offering specific advantages and limitations. Contemporary evidence also supports on-demand rather than routine syndesmotic screw removal, emphasizing patient symptoms, maintained reduction, and functional recovery.
