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

[edit | edit source]
| 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 |
Primary stabiliser.
|
|
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. |
Primary stabiliser. Limits excessive:
|
|
Transverse ligament or the Transverse tibio-fibular ligament (TTFL)
|
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) |

constraining excessive distal fibular motion relative to the tibia and excessive external rotation of the foot on the leg.4
Muscles
[edit | edit source]
Function[edit | edit source]
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 seperate the two bones [2][4]
Motions Available
[edit | edit source]
Range of Motion[edit | edit source]
- 2° fibula external rotation relative to the tibia
- As the ankle joint moves from end range plantar flexion to end range dorsiflexion the ankle mortise widens only about 1mm. [2]
Closed Packed Position[edit | edit source]
Open Packed Position[edit | edit source]
Osteokinematics[edit | edit source]
Arthrokinematics[edit | edit source]
Pathology/Injury[edit | edit source]
{Although the syndesmosis is a joint, in the literature the term syndesmotic injury is used to describe injury of the syndesmotic ligaments.[1]}link
Clinical conditions
high ankle sprain & syndesmosis injury
ankle fracture
