Syndesmosis Joints

In a "syndesmosis joint," the bones are bound together by long fibers of connective tissue that form the "interosseous ligament." Since this ligament is flexible and may be twisted, the joint may allow some slight movement. An example of a syndesmosis is found at the distal ends of the tibia and fibula (lower leg bones), where these bones are joined to form the tibiofibular articulation. The "interosseous membrane" is a layer of tissue that separates the space between the joints. The "interosseous talocalcaneal ligament" joins the talus (one of the ankle bones) to the calcaneous (heel bone).
