A syndesmosis is a type of fibrous joint where two bones are connected by a ligament or an interosseous membrane. This joint allows for limited movement, providing stability while still permitting some flexibility. An example of a syndesmosis is the connection between the tibia and fibula in the lower leg. Syndesmoses are classified as amphiarthroses, meaning they allow slight movement. Unlike other joints, such as synovial joints, syndesmoses do not have a joint cavity. They play a crucial role in maintaining the integrity and function of the skeletal system while allowing for necessary movement.
