Abstract. Syndesmosis injuries occur when there is a disruption of the distal attachment of the tibia and fibula. These injuries occur commonly (up to 18% of ankle sprains), and the incidence increases in the setting of athletic activity. Recognition of these injuries is key to preventing long-term morbidity.
A high ankle sprain, also called a syndesmotic injury, occurs when there is tearing and damage to the high ankle ligaments. These injuries are much less common than a traditional ankle sprain.
What is Syndesmotic Instability? A syndesmosis injury, 'high ankle sprain' occurs usually when the foot is twisted and rotated outwards. The ankle is formed by the Tibia and Fibula bones, held by ligaments termed the Anterior Inferior Tibiofibular Ligament AITFL, and the Posterior Inferior tibiofibular ligamen PITFL.
A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments.
A syndesmosis is a slightly mobile fibrous joint in which bones such as the tibia and fibula are joined together by connective tissue. An example is the distal tibiofibular joint. Injuries to the ankle syndesmosis are commonly known as a "high ankle sprain".
The distal tibiofibular syndesmosis, between the fibula and tibia, is formed by three major ligaments: the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), and the interosseous tibiofibular ligament (ITFL).
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. That's why it's also called the distal tibiofibular syndesmosis.
Most joints in the body are synovial joints. Synovial joints are enclosed by a ligament capsule and contain a fluid, called synovium, that lubricates the joint. The ankle syndesmosis sits next to the ankle synovial joint, where the tibia meets the talus bone.
CAUSES: Injuries of the syndesmosis are commonly associated with ankle fractures. One or more of these four ligaments can be partially or completely ruptured (torn). Without fractures, sprains can occur when the foot is in an up position relative to the ankle and the leg (tibia) externally rotates.

The tibiofibular syndesmosis is a fibrous joint essential for ankle stability, whence the classical comparison with a mortise. Syndesmosis lesions are quite frequent in ankle trauma. This is a key element in ankle stability and lesions may cause pain or instability and, in the longer term, osteoarthritis.
