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),the anterior-inferior tibiofibular ligament (ATIFL), the posterior-inferior tibiofibular ligament (PTIFL) and the transverse tibio-fibular ligament (TTFL). [1][2]
Anatomy[edit | edit source]
Articulating Surfaces[edit | edit source]
- Distal fibula (rough medial convex surface)
- Distal tibia (the triangular notch of the lateral surface)
This forms a mortise for the trochlea of the

| LIGAMENT | DESCRIPTION | PROXIMAL ATTACHMENT | DISTAL ATTACHMENT | ROLE / FUNCTION |
| Distal anterior tibiofibular ligament (ATIFL) |
Trapezoid shape (the tibial insertion is wider). The ligament runs obliquely. |
Anterior tubercle of the distal tibia | Anterior surface of the distal fibula at the lateral malleolus | |
| Posterior or posterior-inferior tibiofibular ligament (PTIFL) |
Strong compact ligament. Known as the Superficial component of the PTIFL. |
Posterior edge of the lateral malleolus |
Posterior tibial tubercle. | |
|
Transverse ligament or the Transverse tibio-fibular ligament (TTFL)[3]
|
Cone shaped. Also known as the Deep component of the PTIFL.
|
Proximal area of the malleolar fossa | Posterior edge of the tibia -- directly posterior to the cartilaginous covering of the inferior tibial articular surface and may extent up to the medial malleolus. | Forms a true labrum. Provides talocrural joint stability. Prevents Posterior translation |

Interosseus ligament (IOL) |

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].

The syndesmosis ligament complex function:
maintains the integrity between the distal tibia and fibula
resist forces (axial, rotational and translational) that attempt to seperate the two bones
