What ligaments are involved in a syndesmosis sprain?
A syndesmotic, or ‘high’ ankle sprain is one that involves the ligaments binding the distal tibia and fibula at the Distal Tibiofibular Syndesmosis. Injuries can occur with any ankle motion, but the most common motions are extreme external rotation or dorsiflexion of the Talus.
What makes up the syndesmosis?
A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments. This definition also applies for the distal tibiofibular syndesmosis, which is a syndesmotic joint formed by two bones and four ligaments.
What is the function of the syndesmosis complex at the distal tibiofibular joint?
Function. The function of syndesmosis ligament complex: Provide strong stabilization and dynamic support to the ankle mortise. Maintain the integrity between the distal tibia and fibula.
Where is syndesmosis found?
The syndesmosis is a fibrous joint held together by ligaments. It’s located near the ankle joint, between the tibia, or shinbone, and the distal fibula, or outside leg bone.
What structures are in the distal tibiofibular syndesmosis?
Structure and Function The osseous portion of the distal tibiofibular syndesmosis consists of the tibia and fibula, and the four connecting ligaments include the anterior inferior tibiofibular ligament, posterior inferior tibiofibular ligament, inferior transverse ligament, and the interosseus ligament.
Is an interosseous membrane a syndesmosis?
An interosseous membrane is a thick dense fibrous sheet of connective tissue that spans the space between two bones forming a type of syndesmosis joint.
How does the syndesmosis work?
The syndesmosis ligament acts as a shock absorber, providing stability and support for your ankle. Its main job is to align the tibia and fibula and keep them from spreading too far apart.
