Anatomical terminology

A syndesmosis is a slightly movable articulation where the contiguous bony surfaces are united by an interosseous ligament, as in the inferior tibiofibular articulation. It comes from the Greek σύν, syn (meaning "with") and δεσμός, desmos (meaning "a band").[1]

If the syndesmosis is torn apart as result of bone fracture, surgeons will sometimes fix the relevant bones together with a syndesmotic screw, temporarily replacing the syndesmosis, or with a tightrope fixation , which is called Syndesmosis Procedure.[2][3] The screw inhibits normal movement of the bones and, thereby, the corresponding joint(s). When the natural articulation is healed, the screw may be removed. The tightrope fixation with elastic fiberwire suture on the other hand allows physiologic motion of the ankle and may be permanent.
