Definition[Bearbeiten]
The term tibiofibular syndesmosis refers to the ligamentous attachment (syndesmosis) between the tibia (shin bone) and fibula (calf bone).
Anatomy[Bearbeiten]
In a broader sense, all ligaments between the tibia and fibula and the entire interosseous membrane are part of the tibiofibular syndesmosis. However, the articulatio tibiofibularis superior is an amphiarthrosis and therefore a true joint. For this reason, the term syndesmosis tibiofibularis is only used clinically and in the narrower anatomical sense to describe the distal ligament connections just above the ankle joint. These include:
- Ligamentum tibiofibulare anterius
- Ligamentum tibiofibulare posterius
- Ligamentum transversum inferius
Task[Bearbeiten]
The syndesmosis tibiofibularis stabilises the ankle joint fork. It can be injured, among other things, in the event of a pulled collateral ligament in a dorsiflexed upper ankle joint.
Clinic[Bearbeiten]
The syndesmosis tibiofibularis can rupture as part of an ankle sprain or an ankle fracture. This is the case, for example, with a Weber B or Weber C fracture.
A bony avulsion of the posterior tibiofibular ligament is part of the trimalleolar fracture.
