Description[edit | edit source]
A syndesmosis is a fibrous joint between two bones and linked by ligaments and a strong membrane. [1]
The distal tibiofibular syndesmosis is a syndesmotic joint. It is formed between the distal tibia and fibula and it is attached by the interosseous ligament (IOL)
and 3 major ligaments: the anterior-inferior tibiofibular ligament (ATIFL), the posterior-inferior tibiofibular ligament (PTIFL) and the transverse tibio-fibular ligament (TTFL). [1][2]

The superficial component originates at the posterior edge of the lateral malleolus and directs proximally and medially to insert in the posterior tibial tubercle. This component would be homologous to the anterior tibiofibular ligament. The term posterior or posteroinferior tibiofibular ligament is usually used to refer to the superficial component (Figs. 20, ,2121).
The deep component is cone shaped and originates in the proximal area of the malleolar fossa to insert in the posterior edge of the tibia. Its insertion is immediately posterior to the cartilaginous covering of the inferior tibial articular surface; the fibers may reach the medial malleolus (Fig. 21). This component is also known as the transverse ligament, forming a true labrum [36] to provide talocrural joint stability and to prevent posterior talar translation [37].
