Physical examination findings that are often positive include the squeeze test and the external rotation test. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. 6- 32), interosseous membranes of the fore – arm and leg, ligamenta flava. These types of joints lack a joint cavity and involve bones that are joined together by either hyaline cartilage or fibrocartilage Figure 9.3.1). The bones are bound together by Sharpey's fibres. "Syndesmosis sprains of the ankle". It comes from the Greek σύν, syn (meaning "with") and δεσμός, desmos (meaning "a band"). At a syndesmosis joint, the bones are more widely separated but are held together by a narrow band of fibrous connective tissue called a ligament or a wide sheet of connective tissue called an interosseous membrane. Fibrous Joints. A syndesmosis is a "fibrous joint in which there is greater distance between the articulatingbones and fibrous connective tissue.
