Syndesmosis
Encyclopedia
A syndesmosis is 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").
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. The screw inhibits normal movement of the bones and, thereby, the corresponding joint(s). When the natural articulation is healed, the screw is removed.

Inferior tibiofibular articulation
The distal tibiofibular joint is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia.Below, to the extent of about 4 mm...

Syndesmotic screw
A syndesmotic screw is a metal screw designed to replace the syndesmosis of the human body, usually temporarily. If the syndosmosis is torn apart as result of bone fracture, surgeons will sometimes fix the relevant bones together with a syndesmotic screw, temporarily replacing the normal...
