Generally result from combined external rotation and dorsiflexion stress.
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.Aug 5, 2014
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. Resist forces (axial, rotational, and translational) that attempt to separate the two bones.
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.

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.
Abstract. The distal tibiofibular syndesmosis (DTFS) is frequently injured during ankle trauma. The sequelae can be significant, including chronic instability, early osteoarthritis and residual pain. The aim of this study is to summarize the current state knowledge about these injuries by answering four questions.
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.
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.Apr 25, 2013
Syndesmosis. A syndesmosis is a non-movable 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".
A syndesmosis injury occurs when the foot twists outwards relative to the leg, a so-called external rotation injury. 2 This type of injury can occur when the ankle is forcefully twisted outwards, or when the foot is planted, and the leg twists inwards.Jul 26, 2020
The tibiofibular syndesmosis is a complex fibrous joint composed of multiple ligaments and a broad fibrous interosseous membrane that spans between the tibia and fibula throughout the length of both bones.May 4, 2021
